MTU Size	Current MTU size. This value is blank if set to Auto.
DNS 1,2,3	IP addresses of the DNS servers, if configured.
VLAN Encapsulation	If enabled, a IEEE 802.1q VLAN header is added to outbound traffic, allowing some Service Providers to control quality of service based on associated IEEE 802.1p priority values.
VLAN ID	VLAN ID used if VLAN Encapsulation is enabled.

Adding a Subinterface

Use the WAN Interface List page from the Internet Setup window to add a subinterface to the SRP. These options are the same as those for configuring a main WAN interface except you cannot configure an Ethernet subinterface for PPTP or L2TP.

The SRP supports multiple logical interfaces per physical port. For Ethernet ports, VLAN interfaces are created as part of an IEEE 802.1p trunk. Multiple PVCs may be created on ADSL interfaces.

The SRP supports up to 5 VLANS which can be used as either Local Area VLANs or WAN subinterfaces. Up to four PVCs can be configured on an ADSL interface.

STEP 1 To add a new logical Internet connection, select the top level WAN from the Internet Setup page and click the Add (page) icon. The Internet Setup window for the new Internet connection opens.

STEP 2 Choose the connection type required by your Internet Service Provide (ISP) as defined in the Ethernet WAN Interface Settings table.

STEP 3 Choose an MTU option from the drop-down list. Unless a change is required by your ISP, we recommend that you set the MTU method to Auto, which allows the voice system to automatically choose the size. The default size is 1500 bytes.

To specify another MTU size, choose Custom from the drop-down list and enter the size in bytes. The standard size for Ethernet networks is 1500 bytes. For PPPoE connections, the standard size is 1492 bytes.

STEP 4 Click Submit to save your changes.

The new connection is added to the WAN Interface List on the Internet Setup page.

Ethernet WAN Interface Settings
Field Description
WAN WAN1 is the interface identity for the SRP's WAN port. This value cannot be changed.
VLAN ID VLAN identity for the interface or subinterface. This value cannot be changed after the interface is first created.
Connection Type Type of Internet connection that your ISP provides.
	Automatic Configuration/DCHPConnection type often used with cable modems. Choose this option if your ISP dynamically assigns an IP address on connection. No other information is required for this connection type.
	Static IPChoose this option if your ISP provides you with a static (permanent) IP address and does not assign it dynamically. Enter the assigned IP Address, Subnet Mask, and Default Gateway IP address.PPPoEChoose this option if your ISP uses PPPoE (Point-to-Point Protocol over Ethernet).Enter the User Name and Password for your ISP account and the Service Name if required by your ISP. Select either the Connect on Demand or Keep Alive option.Connect on DemandOpens a connection only when a user attempts to connect to the Internet. The connection automatically terminates if there is a period of inactivity longer than the specified Max Idle Time (in minutes). We recommend this option if your billing is based on the time that you are connected.NOTE PCs often send information to the Internet even if email or a web browser is not being used. This may keep the session connected for longer than expected.Keep AliveKeeps you connected to the Internet indefinitely, even when your connection sits idle.
	PPTPSelect this option if your ISP uses PPTP (Point to Point Tunneling Protocol).Enter the PPTP Server IP address and the User Name and Password for your account.If your service provider does not dynamically assign an IP address, disable DHCP and enter the address, mask and gateway details provided for your account.Select either the Connect on Demand or Keep Alive option.L2TPSelect this option if your ISP uses L2TP (Layer 2 Tunneling Protocol) and has provided you with a static IP address.Enter the L2TP Server IP address and the User Name and Password for your account.If your service provider does not dynamically assign an IP address, disable DHCP and enter the address, mask and gateway details provided for your account.Select either theConnect on Demand or Keep Alive option.
Maximum Transmission Unit (MTU)	Size, in bytes, of the largest packet that can be sent through the network. This value is typically 1500 bytes but might need to be lower for some broadband services. Check with your service provider for specific requirements.
Static DNS 1-3 (Optional)	Enter the IP addresses of up to three Domain Name System (DNS) servers, or leave the fields blank to allow a DNS server to be assigned dynamically.

Encapsulation Settings

This section describes the ADSL Encapsulation Settings that you can choose from in the Internet Setup page under VC settings.

Encapsulation is the protocol used between your broadband gateway and your ISP's servers. Most of the encapsulations are defined in Internet standards called Requests for Comments (RFCs). Two are derived from the Point-to-Point Protocol (PPP): PPP over Ethernet (PPPoE) and PPP over ATM (PPPoA).

IPoA Settings

Choose IPoA for direct encapsulation of IP traffic over the DSL ATM virtual circuit. Enter the required information as provided by your ISP: Internet IP Address, Subnet Mask, and Default Gateway IP address. Optionally, you can enter the IP addresses of the primary and secondary DNS servers.

IPoA Settings
Field Description
Internet IP Address and Subnet Mask	The SRP's IP Address and Subnet Mask as seen by external users on the Internet (including your ISP). Your ISP provides you with this information.
Default Gateway Your	ISP provides you with the Gateway IP Address.
Primary/Secondary DNS	Use to define one or two DNS servers. The SRP uses these to resolve domain names for locally configured features and may also pass these on to local clients through DHCP.

PPPoE Settings

Choose PPPoE to run Ethernet encapsulated PPP over the DSL ATM virtual circuit. Enter the user name and password provided to you by your ISP. Optionally, you can also specify a PPP service name, if one is provided by your service provider.

PPPoE Settings
Field Description
Username and Password	Strings that your ISP has instructed you to use. The user name can be called a “username,” “login name,” or “login.”
Service Name String required by some ISPs. Fill this in only if your ISP requires it.
Connect on Demand	Connects the broadband gateway to your ISP when a connection is needed and disconnects it when the line to your ISP is idle for a given amount of timeYou can also adjust the maximum idle time; the default setting is 20 minutes. The alternative to Connect on Demand is Keep Alive (see next). In most cases you can choose either option without consulting your ISP.

Failover and Recovery

An Internet connection can be established through the WAN port or a wireless modem plugged into the USB port. See www.cisco.com/go/srp500 for more details on compatible USB modem devices.

While both Ethernet and a USB modem may be connected, only one can be used to establish a link at a time. Whenever the Internet connection fails, the SRP automatically attempts to bring up another connection on another interface. This feature is called Failover. When the original Internet connection is restored, reverts to using this path and drops the backup connection. This feature is called Recovery.

STEP 1 Click Interface Setup > Failover & Recovery. The Failover & Recovery window opens.

STEP 2 Click Enabled to enable Connection Recovery.

When enabled, the SRP sets the Ethernet interface to the highest priority and also enables Interface Connection Failover. If the Internet connection fails, the SRP automatically attempts to bring up the mobile network connection on the USB interface (if available). Whenever the Internet connection recovers, the SRP automatically reverts to using this instead of the backup interface.

NOTE Mobile Connection Mode must be set to Auto to use Ethernet Connection Recovery.

STEP 3 Enter a failover timeout value.

WAN Interface	Choose the WAN Interface from which the related DHCP information, specifically DNS, is obtained.
Option 66 Provides provisioning server address information to hosts requesting this option. Server information can be defined in one of three ways:Local TFTP Server: The SRP uses its own TFTP server to source provisioning files so it returns its own local IP address to the client.Remote TFTP Server: If the SRP was configured by using this method, it uses the server information it received through option 66 on its WAN interface in response to local client requests.Manual TFTP Server: Allows the manual configuration of a configuration server address. While this option is typically used to provide either an IP address or a fully qualified hostname, the SRP will also accept and offer a full URL including protocol, path and filename to meet the requirements of specific clients.
Option 67 Provides a	configuration/bootstrap filename to hosts requesting this option. This is used in conjunction with option 66 to allow the client to form an appropriate TFTP request for the file.
DNS Proxy	If DNS proxy is enabled, local clients are offered the SRP Local IP Address to use for DNS requests. The SRP then proxies these requests to the DNS servers it was configured with. See the note about DNS in Internet Setup, page 26.If DNS proxy is disabled, then DHCP clients will be offered DNS server information based on the following:If the Static DNS field is configured, then that server alone will be offered to clients.If the Static DNS field is not configured up to three servers are offered, first from the global Internet Options static configuration and then from the WAN interface nominated above.
Starting IP Address IP address of the first address in this pool.
Maximum DHCP Users	Maximum number of devices that you want the DHCP server to assign IP addresses to. This number is affected by the subnet mask and starting IP address. It cannot be greater than 1024. The default is 50.

CTS Protection Mode	The SRP automatically uses CTS (Clear-To-Send) Protection Mode when your Wireless-N and Wireless-G products are experiencing severe problems and are not able to transmit to the SRP in an environment with heavy 802.11b traffic. This function boosts the SRP's ability to catch all Wireless-N and Wireless-G transmissions but can impact performance. The default is Auto.
DTIM Interval This value, between 1 and 255, indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the SRP has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 1.
Fragmentation Threshold	This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.
Beacon Interval Enter	a value between 40 and 3500 milliseconds. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the SRP to synchronize the wireless network. The default value is 100.
Power Control Choose	high, middle, or low to specify the range of the wireless network. The default is high, which is a normal power level.

Configuring Voice Services

This section describes how to configure your SRP to meet the customer's requirements for voice services. It includes the following topics:

• Understanding Voice Port Operations
• Managing Caller ID Services
• Silence Suppression and Comfort Noise Generation
• Configuring Dial Plans
• Secure Call Implementation

Understanding Voice Port Operations

The SRP520 has a number of voice ports that allow calls to be made from locally connected analog handsets or fax machines by using SIP based Internet phone services. In addition to the four handset (FXS) ports, the SRP also has a single line (FXO) port that can be used to place calls to the telephone network in the event of broadband or even SRP failure.

Note: The SRP520 line port is a passive interface that connects the PSTN line with FXS port 1 during failure conditions. Calls cannot be routed dynamically to this interface under normal operating conditions.

The SRP maintains the state of each call made through the FXS interface and makes the proper reaction to user input events (such as on/off hook or hook flash). Because the SRP uses the Session Initiation Protocol (SIP), it is compatible with most Internet Telephony Service Provider offerings.

SRP Voice Features

The SRP is equipped with fully featured, programmable voice ports that can be custom provisioned within a wide range of configuration parameters. The following sections describe the factors that contribute to voice quality:

• Supported Codecs
• SIP Proxy Redundancy
• Other SRP Voice Features

Supported Codecs

The SRP voice ports support the following codecs:

Codec Description
G.711 (A-law and mu-law)	Very low complexity codecs that support uncompressed 64 kbps digitized voice transmissions at one through ten 5 ms voice frames per packet. These codecs provide the highest narrow-band voice quality and uses the most bandwidth of any of the available codecs.
G.726-32 Low complexity	codec that supports compressed32 kbps digitized voice transmission at one through ten 10 ms voice frames per packet. This codec provides high voice quality.
G.729a ITU G.729 voice coding algorithm used to compress digitized speech. G.729a is a reduced complexity version of G.729 requiring about half the processing power of G.729. The G.729 and G.729a bit streams are compatible and interoperable, but not identical.

The administrator can select the preferred codecs to be used for each line. See Audio Configuration, page 171.

In addition, negotiation of the optimal voice codec sometimes depends on the ability of a device to match a codec name with the codec used by the far-end device. You can individually name the various codecs so that the SRP can successfully negotiate the codec with the far-end equipment. For more information, see Audio Configuration, page 171.

SIP Proxy Redundancy

In typical commercial IP Telephony deployments, all calls are established through a SIP proxy server. A typical SIP proxy server can handle thousands of subscribers. It is important that a backup server be available so that an active server can be temporarily switched out for maintenance. The SRP supports the use of backup SIP proxy servers (through DNS SRV) so that service disruption is minimized.

An easy way to support proxy redundancy is to configure your DNS server with a list of SIP proxy addresses. The SRP can be instructed to contact a SIP proxy server in a domain named in the SIP message. The SRP consults the DNS server to get a list of hosts in the given domain that provides SIP services. If an entry exists, the DNS server returns an SRV record that contains a list of SIP proxy servers for the domain, with their host names, priority, listening ports, and so on. The SRP tries to contact the list of hosts in the order of their stated priority.

If the SRP is currently using a lower priority proxy server, it periodically probes the higher priority proxy to see whether it is back on line, and switches back to the higher priority proxy when possible. SIP Proxy Redundancy is configured in the Line pages (1–4) in the Services Ready Platform Configuration Utility. See Line Pages (1–2), page 156.

Other SRP Voice Features

The following table summarizes other voice features provided by the SRP.

Feature Description
Silence Suppression Voice	Activity Detection (VAD) with SilenceSuppression is a means of increasing the number of calls supported by the network by reducing the average bandwidth required for a single call. VAD uses a sophisticated algorithm to distinguish between speech and non-speech signals. Based on the current and past statistics, the VAD algorithm decides whether or not speech is present. If the VAD algorithm decides speech is not present, the silence suppression and comfort noise generation is activated. This is accomplished by removing and not transmitting the natural silence that occurs in normal two-way connection. The IP bandwidth is used only when someone is speaking. During the silent periods of a telephone call, additional bandwidth is available for other voice calls or data traffic because the silence packets are not being transmitted across the network.Comfort Noise Generation provides artificially-generated background white noise (sounds), designed to reassure callers that their calls are still connected during silent periods. If Comfort Noise Generation is not used, the caller may think the call has been disconnected because of the “dead silence” periods created by the VAD and Silence Suppression feature.
Modem and Fax Pass-Through	·Modem pass-through mode can be triggered only by predialing the number set in the Modem Line Toggle Code. See Regional Page, page 136.·FAX pass-through mode is triggered by the detection of a CED/CNG tone or an NSE event.·Echo canceller is automatically disabled for Modem passthrough mode.·Echo canceller is disabled for FAX pass-through if the parameter FAX Disable ECAN (Line 1 or 2 tab) is set to “yes” for that line (in that case FAX pass-through is the same as Modem pass-through).·Call waiting and silence suppression is automatically disabled for both FAX and Modem pass-through. In addition, out-of-band DTMF transmission is disabled during modem or fax passthrough.
Adaptive Jitter Buffer The SRP can buffer incoming voice packets to minimize the impact of variable network delays. This process is known as jitter buffering. The size of the jitter buffer adapts reactively to suit changing network conditions.The SRP has a Network Jitter Level control setting for each line of service. The jitter level determines how aggressively the SRP tries to shrink the jitter buffer over time to achieve a lower overall delay. If the jitter level is higher, it shrinks more gradually. If jitter level is lower, it shrinks more quickly.Adaptive Jitter Buffer is configured in the Line pages. See Line Pages (1–2), page 156.
Secure Calls A user (if enabled by service provider or administrator) has the option to make an outbound call secure in the sense that the audio packets in both directions are encrypted.
Adjustable Audio Frames Per Packet	This feature allows the user to set the number of audio frames contained in one RTP packet. Packets can be adjusted to contain from 1–10 audio frames. Increasing the number of packets decreases the bandwidth utilized, but it also increases delay and may affect voice quality. RTP packets are configured in the SIP page. See SIP Page, page 120.
DTMF Relay The SRP may relay DTMF digits as out-of-band events to preserve the fidelity of the digits. This can enhance the reliability of DTMF transmission required by many IVR applications such as dial-up banking and airline information. DTMF Relay is configured in the DTMF Tx Mode parameter in the Line pages. See Line Pages (1–2), page 156.
Call Progress Tones The SRP has configurable call progress tones. Call progress tones are generated locally on the SRP so that an end user is advised of status (such as ringback). Parameters for each type of tone (for instance a dial tone played back to an end user) may include frequency and amplitude of each component, and cadence information. The Call Progress tones are configured in the Regional page, See Regional Page, page 136.
Call Progress Tone Pass Through	This feature allows the user to hear the call progress tones (such as ringing) that are generated from the far-end network.
Echo Cancellation Impedance mismatch between the telephone and the IP Telephony gateway phone port can lead to near-end echo. The SRP has a near-end echo canceller that compensates for impedance match. The SRP also implements an echo suppressor with Comfort Noise Generator (CNG) so that any residual echo is not noticeable. Echo Cancellation is configured from the Line pages. See Line Pages (1–2), page 156.
Signaling Hook Flash Event	The SRP can signal hook flash events to the proxy during a connected call. This feature can be used to provide advanced mid-call services with third-party-call control.Depending on the features that the service provider offers using third-party-call-control, the following ATA features may be disabled to correctly signal a hookflash event to the softswitch:Call Waiting Service:Refers to the call waiting serv parameter in the Line pages.Three Way Conference Service:Refers to the three-way conf serv parameter in the Line pages.Three Way Call Service:Refers to the three-way call serv parameter in the Line pages.You can configure the length of time allowed for detection of a hook flash using the Hook Flash Timer parameter on the Regional page. SeeRegional Page, page 136.
Configurable Dial Plan with Interdigit Timers	The SRP has three configurable interdigit timers:Initial timeout (T)—Signals that the handset is off the hook and that no digit has been pressed yet.Long timeout (L)—Signals the end of a dial string; that is, no more digits are expected.Short timeout (S)—Used between digits; that is after a digit is pressed a short timeout prevents the digit from being recognized a second time.SeeConfiguring Dial Plans, page 102for more information.
Polarity Control The SRP allows the polarity to be set when a call is connected and when a call is disconnected. This feature is required to support some pay phone system and answering machines.Polarity Control is configured in the Line pages.See Line Pages (1-2), page 156.
Calling Party Control Calling	Party Control (CPC) signals to the called party equipment that the calling party has hung up during a connected call by removing the voltage between the tip and ring momentarily. This feature is useful for auto answer equipment, which then knows when to disengage.CPC is configured in the Regional page. SeeRegional Page, page 136.
Report Generation and Event Logging	The SRP reports a variety of status and error reports to assist service providers to diagnose problems and evaluate the performance of their services. The information can be queried by an authorized agent, using HTTP with digest authentication, for instance. The information may be organized as an XML page or HTML page.Report Generation and Event Logging are configured from the System page. SeeSystemPage, page 119.
Syslog and Debug Server Records	Syslog and Debug Sever Records list more details than Report Generation and Event Logging. Using the configuration parameters, the SRP allows you to select which type of activity/events should be logged.Syslog and Debug Server allow the information captured to be sent to a Syslog Server. Syslog and Debug Server Records are configured from the System page. SeeSystem Page, page 119.
SIP Over TLS The SRP allows the use of SIP over TransportLayer Security (TLS). SIP over TLS is designed to eliminate the possibility of malicious activity by encrypting the SIP messages between the service provider and the end user. SIP over TLS relies on the widely-deployed and standardized TLS protocol. SIP Over TLS encrypts only the signaling messages and not the media. A separate secure protocol such as Secure Real-Time Transport Protocol (SRTP) can be used to encrypt voice packets. SIP over TLS is configured in the SIP Transport parameter configured in the Line pages. SeeLine Pages(1–2),page 156.

Registering to the Service Provider

To use an Internet phone service, you must register your SRP to the Internet Telephony Service Provider (ITSP).

NOTE Each line tab must be configured separately. Each line tab can be configured for a different ITSP.

STEP 1 Log in to the Configuration Utility. If prompted, enter the administrative logon provided by the Service Provider. The default username and password are both admin.

STEP 2 Under the Voice menu, click the Line (Line 1-2) to choose the line interface that you want to modify.

STEP 3 In the Proxy and Registration section, enter the Proxy.

STEP 4 In the Subscriber Information section, enter the User ID and Password.

Proxy and Registration Proxy: Outbound Proxy: Use Outbound Proxy: Register: Register Expires: Use DNS SRV: Proxy Fallback Intl: Voice Mail Server: Subscriber Information Display Name: Password: Auth ID: Mini Certificates: SRTP Private Key: User OB Proxy In Dialog: yes Make Call Without Reg: no Ams Call Without Reg: no DNS SRV Auto Prefix: no Proxy Redundancy Method: Normal Matrix Subscription Express: 2147483647 User ID: Use Auth ID: no Directory Number:

NOTE These are the minimum settings for most ITSP connections. Enter the account information as required by your ITSP.

STEP 5 Click Submit to save your settings. The voice service will restart.

STEP 6 To verify your progress, perform the following tasks:

a. From the Voice navigation pane, click Info. Scroll down to the Line section of the page for the line you configured. Verify that the line is registered.
b. Use an external phone to place an inbound call to the telephone number that was assigned by your ITSP. Assuming that you have left the default settings in place, the phone should ring and you can pick up the phone to get two-way audio.
c. If the line is not registered, you may need to refresh the browser several times because it can take a few seconds for the registration to complete. Also verify that DNS is configured properly.

Managing Caller ID Services

The choice of Caller ID (CID) method is dependent on your area/region. This option is located on the Voice > Regional page under the Miscellaneous area. To configure CID, use the following parameters.

Caller ID Method

Bellcore (N.Amer,China)—CID, CIDCW, and VMWI. FSK sent after first ring (same as ETSI FSK sent after first ring) (no polarity reversal or DTAS). This is the default setting.

DTMF (Finland, Sweden)—CID only. DTMF sent after polarity reversal (and no DTAS) and before first ring

DTMF (Denmark)—CID only. DTMF sent before first ring with no polarity reversal and no DTAS.

ETSI DTMF—CID only. DTMF sent after DTAS (and no polarity reversal) and before first ring.

ETSI DTMF With PR—CID only. DTMF sent after polarity reversal and DTAS and before first ring.

ETSI DTMF After Ring—CID only. DTMF sent after first ring (no polarity reversal or DTAS).

ETSI FSK—CID, CIDCW, and VMWI. FSK sent after DTAS (but no polarity reversal) and before first ring. Waits for ACK from CPE after DTAS for CIDCW.

ETSI FSK With PR (UK)—CID, CIDCW, and VMWI. FSK is sent after polarity reversal and DTAS and before first ring. Waits for ACK from CPE after DTAS for CIDCW. Polarity reversal is applied only if equipment is on hook.

DTMF (Denmark) With PR—CID only. DTMF sent after polarity reversal (and no DTAS) and before first ring.

Caller ID FSK Standard

The SRP supports bell 202 and v.23 standards for caller ID generation. Select the FSK standard you want to use, bell 202 or v.23. The default is bell 202.

There are three types of Caller IDs:

• On Hook Caller ID Associated with Ringing—Type of Caller ID is used for incoming calls when the attached phone is on hook. See the following figure (a) – (c). All CID methods can be applied for this type of CID.
• On Hook Caller ID Not Associated with Ringing—Used to send VMWI signal to the phone to turn the message waiting light on and off (see Figure 1 (d) and (e). This is available only for FSK-based CID methods: (Bellcore, ETSI FSK, and ETSI FSK With PR).
• Off Hook Caller ID—Used to deliver caller-id on incoming calls when the attached phone is off hook (see the following figure). This can be call waiting caller ID (CIDCW) or to notify the user that the far end party identity has changed or been updated (such as due to a call transfer). This is available only for FSK-based CID methods: (Bellcore, ETSI FSK, and ETSI FSK With PR).

Optimizing Fax Completion Rates

Issues can occur with fax transmissions over IP networks, even with the T.38 standard, which is supported by the SRP. You can adjust several settings on your SRP to optimize your fax completion rates.

STEP 1 Ensure that you have enough bandwidth for the uplink and the downlink.

• For G.711 fallback, it is recommend to have approximately 100 kbps.
• For T.38, allocate at least 50 kbps.

STEP 2 To optimize G.711 fallback fax completion rates, set the following on the Line tab of your SRP:

■ Network Jitter Buffer: very high
- Jitter buffer adjustment: disable
- Call Waiting: no

- 3 Way Calling: no

- Echo Canceller: no

- Silence suppression: no

- Preferred Codec: G.711

- Use pref. codec only: yes

If you are using a Cisco media gateway for PSTN termination, disable T.38 (fax relay) and enable fax using modem passthrough. For example:

modem passthrough nse payload-type 110 codec g711ulaw fax rate disable fax protocol pass-through g711ulaw

STEP 3 Enable T.38 fax on the SRP by configuring the following parameter on the Line tab for the FXS port to which the FAX machine is connected:

FAX_Passthru_Method: ReINVITE

NOTE If a T.38 call cannot be set-up, then the call automatically reverts to G.711 fallback.

STEP 4 If you are using a Cisco media gateway use the following settings:

Make sure the Cisco gateway is correctly configured for T.38 with the SPA dialpeer. For example:

fax protocol T38
fax rate voice
fax-relay ecm disable
fax nsf 000000
no vad 

Fax Troubleshooting

If you have problems sending or receiving faxes, complete the following steps:

STEP 1 Verify that your fax machine is set to a speed between 7200 and 14400.

STEP 2 Send a test fax in a controlled environment between two ATAs.

STEP 3 Determine the success rate.

STEP 4 Monitor the network and record the statistics for Jitter, Loss, and Delay.

STEP 5 If faxes fail consistently, capture a copy of the SRP configuration by downloading the following file. You can then send this file to Technical Support.

http:///admin/config.xml&xuser=admin&xpassword=

If you are using a web browser, choose the option to view source for the resulting page and save this file locally.

STEP 6 Enable and capture the debug list.

NOTE You can also capture data using a sniffer trace.

STEP 7 Identify the type of fax machine connected to the device.

STEP 8 Contact technical support:

• If you are an end user of VoIP products, contact the reseller or Internet telephony service provider (ITSP) that supplied the equipment.
• If you are an authorized Cisco partner, contact Cisco technical support at: www.cisco.com/support.

Silence Suppression and Comfort Noise Generation

Voice Activity Detection (VAD) with Silence Suppression is a means of increasing the number of calls supported by the network by reducing the required bandwidth for a single call. VAD uses a sophisticated algorithm to distinguish between speech and non-speech signals. Based on current and past statistics, the VAD algorithm decides whether or not speech is present. If the VAD algorithm decides speech is not present, the silence suppression and comfort noise generation is activated. This is accomplished by suppressing the transmission of the natural silence that occurs in normal two-way connection. The IP bandwidth is therefore used only when someone is speaking. During the silent periods of a telephone call, additional bandwidth is available for other voice calls or data traffic because the silence packets are not being transmitted across the network.

Comfort Noise Generation provides artificially-generated background white noise (sounds), designed to reassure callers that their calls are still connected during silent periods. If Comfort Noise Generation is not used, the caller may think the call has been disconnected because of the “dead silence” periods created by the VAD and Silence Suppression feature.

Silence suppression is configured from the Line (1-2) pages. tabs. See Line Pages (1–2), page 156.

Configuring Dial Plans

Dial plans determine how dialed digits are interpreted and transmitted. They also determine whether the dialed number is accepted or rejected. You can use a dial plan to facilitate dialing or to block certain types of calls such as long distance or international. This section includes information that you need to understand dial plans, as well as procedures for configuring your own dial plans. This section includes the following topics:

• About Dial Plans
• Editing Dial Plans

About Dial Plans

This section provides information to help you understand how dial plans are implemented. See the following topics:

• Digit Sequences
• Digit Sequence Examples
• Acceptance and Transmission the Dialed Digits
• Dial Plan Timer (Off-Hook Timer)
• Interdigit Long Timer (Incomplete Entry Timer)
• Interdigit Short Timer (Complete Entry Timer)

Digit Sequences

A dial plan contains a series of digit sequences, separated by the “I” character. The entire collection of sequences is enclosed within parentheses. Each digit sequence within the dial plan includes a series of elements, which are individually matched to the keys that the user presses.

NOTE White space is ignored, but may be used for readability.

Digit Sequence Function
0 1 2 3 4 5 6 7 8 9 0* #	Enter any of these characters to represent a key that the user must press on the phone keypad.
x	Enter x to represent any character on the phone keypad.
[sequence]	Enter characters within square brackets to create a list of accepted key presses. The user can press any one of the keys in the list.Numeric range: For example, you would enter [2-9] to allow the user to press any one digit from 2 through 9.Numeric range with other characters: For example, you would enter [35-8*] to allow the user to press 3, 5, 6, 7, 8, or *.
.(period)	Enter a period for element repetition. The dial plan accepts zero or more entries of the digit. For example, 01. allows users to enter 0, 01, 011, 0111, and so on.
<dialed:substituted> Use this format to indicate that certain dialed digits are replaced by other characters when the sequence is transmitted. The dialed digits can be zero or more characters.EXAMPLE 1:<8:1650>xxxxxxxWhen the user presses 8 followed by a seven digit number, the system automatically replaces the dialed 8 with 1650. If the user dials 85550112, the system transmits 16505550112.EXAMPLE 2:<:1>xxxxxxxxxIn this example, no digits are replaced. When the user enters a 10-digit string of numbers, the number 1 is added at the beginning of the sequence. If the user dials 9725550112, the system transmits 19725550112.
, (comma)	Enter a comma between digits to play an “outside line” dial tone after a user-entered sequence. EXAMPLE: 9, 1xxxxxxxxxxx An “outside line” dial tone is sounded after the user presses 9, and the tone continues until the user presses 1.
! (exclamation point)	Enter an exclamation point to prohibit a dial sequence pattern. EXAMPLE: 1900xxxxxxxxx! The system rejects any 11-digit sequence that begins with 1900.
*xx Enter an asterisk to allow	the user to enter a 2-digit star code.
S0 or L0 Enter S0 to reduce	the short inter-digit timer to 0 seconds, or enter L0 to reduce the long inter-digit timer to 0 seconds.

Digit Sequence Examples

The following examples show digit sequences that you can enter in a dial plan.

In a complete dial plan entry, sequences are separated by a pipe character (I), and the entire set of sequences is enclosed within parentheses.

EXAMPLE: ([1-8]xx | 9, xxxxxxxx | 9, <:1>[2-9]xxxxxxxxxx | 8, <:1212>xxxxxxxxx | 9, 1 [2-9] xxxxxxxxxxxx | 9, 1 900 xxxxxxxx ! | 9, 011xxxxxxxx. | 0 | [49]11) 

Extensions on your system

EXAMPLE: ( [1-8]xx | 9, xxxxxxxx | 9, <:1>[2-9]xxxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxxxxx | 9, 1 900 xxxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 ) 

[1-8] xx Allows a user dial any three-digit number that starts with the digits 1 through 8. If your system uses four-digit extensions, you would instead enter the following string: [1-8]xxx

Local dialing with seven-digit number

EXAMPLE: ( [1-8]xx | 9, xxxxxxxx | 9, <:1>[2-9]xxxxxxxxxx | 8, <:1212>xxxxxxxxx | 9, 1 [2-9] xxxxxxxxxxxxx | 9, 1 900 xxxxxxxx ! | 9, 011xxxxxx. | 0 | [49]111) 

9, xxxxxxx After a user presses 9, an external dial tone sounds. The user can then dial any seven-digit number, as in a local call.

Local dialing with 3-digit area code and a 7-digit local number

EXAMPLE: ( [1-8]xx | 9, xxxxxxxx | 9, <:1>[2-9]xxxxxxxxxx | 8, <:1212>xxxxxxxxx | 9, 1 [2-9] xxxxxxxxxxxx | 9, 1 900 xxxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 ) 

9, <:1> [2-9]xxxxxxxxx This example is useful where a local area code is required. After a user presses 9, an external dial tone sounds. The user must enter a 10-digit number that begins with a digit 2 through 9. The system automatically inserts the 1 prefix before transmitting the number to the carrier.

Local dialing with an automatically inserted 3-digit area code

EXAMPLE: ( [1-8]xx | 9, xxxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxxxxx | 9, 1 900 xxxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 ) 

8, <:1212>xxxxxxxx This is example is useful where a local area code is required by the carrier but the majority of calls go to one area code. After the user presses 8, an external dial tone sounds. The user can enter any seven-digit number. The system automatically inserts the 1 prefix and the 212 area code before transmitting the number to the carrier.

U.S. long distance dialing

EXAMPLE: ( [1-8]xx | 9, xxxxxxxx | 9, <:1>[2-9]xxxxxxxxx |
8, <:1212>xxxxxxxxx | 9, 1 [2-9] xxxxxxxxxxxx | 9, 1 900 xxxxxxxx ! | 9,
011xxxxxx. | 0 | [49]11 ) 

9, 1 [2-9] xxxxxxxxxxx After the user presses 9, an external dial tone sounds. The user can enter any 11-digit number that starts with 1 and is followed by a digit 2 through 9.

Blocked number

EXAMPLE: ( [1-8]xx | 9, xxxxxxxx | 9, <:1>[2-9]xxxxxxxxx |
8, <:1212>xxxxxxxxx | 9, 1 [2-9] xxxxxxxxxxxx | 9, 1 900 xxxxxxxx ! |
9, 011xxxxxx. | 0 | [49]11 ) 

9, 1 900 xxxxxxxx ! This digit sequence is useful if you want to prevent users from dialing numbers that are associated with high tolls or inappropriate content, such as 1-900 numbers in the U.S. After the user press 9, an external dial tone sounds. If the user enters an 11-digit number that starts with the digits 1900, the call is rejected.

U.S. international dialing

EXAMPLE: ( [1-8]xx | 9, xxxxxxxx | 9, <:1>[2-9]xxxxxxxxxx | 8, <:1212>xxxxxxxxx | 9, 1 [2-9] xxxxxxxxxxxx | 9, 1 900 xxxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 ) 

9, 011xxxxxx. After the user presses 9, an external dial tone sounds. The user can enter any number that starts with 011, as in an international call from the U.S.

Informational numbers

EXAMPLE: ([1-8]xx | 9, xxxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9] xxxxxxxxxx | 9, 1 900 xxxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11) 

0 | [49]11 This example includes two digit sequences, separated by the pipe character. The first sequence allows a user to dial 0 for an operator. The second sequence allows the user to enter 411 for local information or 911 for emergency services.

Acceptance and Transmission the Dialed Digits

When a user dials a series of digits, each sequence in the dial plan is tested as a possible match. The matching sequences form a set of candidate digit sequences. As more digits are entered by the user, the set of candidates diminishes until only one or none are valid. When a terminating event occurs, the SRP either accepts the user-dialed sequence and initiates a call, or else rejects the sequence as invalid. The user hears the reorder (fast busy) tone if the dialed sequence is invalid.

The following table explains how terminating events are processed.

Terminating Event Processing
The dialed digits do not match any sequence in the dial plan.	The number is rejected.
The dialed digits exactly match one sequence in the dial plan.	·If the sequence is allowed by the dial plan, the number is accepted and is transmitted according to the dial plan.·If the sequence is blocked by the dial plan, the number is rejected.
A timeout occurs. The number is rejected if the dialed digits are not matched to a digit sequence in the dial plan within the time specified by the applicable interdigit timer.·The Interdigit Long Timer applies when the dialed digits do not match any digit sequence in the dial plan. The default value is 10 seconds.·The Interdigit Short Timer applies when the dialed digits match one or more candidate sequences in the dial plan. The default value is 3 seconds.
The user presses the # key.	·If the sequence is complete and is allowed by the dial plan, the number is accepted and is transmitted according to the dial plan.·If the sequence is incomplete or is blocked by the dial plan, the number is rejected.

Dial Plan Timer (Off-Hook Timer)

You can think of the Dial Plan Timer as “the off-hook timer.” This timer starts counting when the phone goes off hook. If no digits are dialed within the specified number of seconds, the timer expires and the null entry is evaluated. Unless you have a special dial plan string to allow a null entry, the call is rejected. The default value is 5.

Syntax for the Dial Plan Timer

SYNTAX: (Ps<:n> | dial plan )

• s: The number of seconds; if no number is entered after B, the default timer of 5 seconds applies.
• n: (optional): The number to transmit automatically when the timer expires; you can enter a valid number. No wildcard characters are allowed because the number will be transmitted as shown. If you omit the number

substitution, <:n>, then the user hears a reorder (fast busy) tone after the specified number of seconds.

Examples for the Dial Plan Timer

- Allow more time for users to start dialing after taking a phone off hook.

EXAMPLE: (P9 | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2 9]xxxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx) 

P9 After taking a phone off hook, a user has 9 seconds to begin dialing. If no digits are pressed within 9 seconds, the user hears a reorder (fast busy) tone. By setting a longer timer, you allow more time for users to enter the digits.

- Create a hotline for all sequences on the System Dial Plan

EXAMPLE: (P9<:23> | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxxx | 9,8,011xx. | 9,8,xx. | [1-8] xx) 

P9<:23> After taking the phone off hook, a user has 9 seconds to begin dialing. If no digits are pressed within 9 seconds, the call is transmitted automatically to extension 23.

- Create a hotline on a line button for an extension

EXAMPLE: (P0 <:1000>) 

With the timer set to 0 seconds, the call is transmitted automatically to the specified extension when the phone goes off hook.

Interdigit Long Timer (Incomplete Entry Timer)

You can think of this timer as the “incomplete entry” timer. This timer measures the interval between dialed digits. It applies as long as the dialed digits do not match any digit sequences in the dial plan. Unless the user enters another digit within the specified number of seconds, the entry is evaluated as incomplete, and the call is rejected. The default value is 10 seconds.

NOTE This section explains how to edit a timer as part of a dial plan. Alternatively, you can modify the Control Timer that controls the default interdigit timers for all calls. See Resetting the Control Timers, page 110.

Syntax for the Interdigit Long Timer

SYNTAX: L:S, ( dial plan )

s: The number of seconds; if no number is entered after L:, the default timer of 5 seconds applies. The timer sequence appears to the left of the initial parenthesis for the dial plan.

Example for the Interdigit Long Timer

EXAMPLE: L:15, (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxxx | 9,8,011xx. | 9,8,xx. | [1-8]xx)

L:15, This dial plan allows the user to pause for up to 15 seconds between digits before the Interdigit Long Timer expires.

Interdigit Short Timer (Complete Entry Timer)

You can think of this timer as the “complete entry” timer. This timer measures the interval between dialed digits. It applies when the dialed digits match at least one digit sequence in the dial plan. Unless the user enters another digit within the specified number of seconds, the entry is evaluated. If it is valid, the call proceeds. If it is invalid, the call is rejected. The default value is 3 seconds.

Syntax for the Interdigit Short Timer

SYNTAX 1: S:S, ( dial plan )

Use this syntax to apply the new setting to the entire dial plan within the parentheses.

• SYNTAX 2: sequence Ss

Use this syntax to apply the new setting to a particular dialing sequence.

s: The number of seconds; if no number is entered after S, the default timer of 5 seconds applies.

Examples for the Interdigit Short Timer

- Set the timer for the entire dial plan.

EXAMPLE: S:6, (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)

s:6, While entering a number with the phone off hook, a user can pause for up to 15 seconds between digits before the Interdigit Short Timer expires.

- Set an instant timer for a particular sequence within the dial plan.

EXAMPLE: (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxxS0 | 9,8,011xx. | 9,8,xx. | [1-8] xx)

9, 8, 1 [2-9]xxxxxxxxxxS0 With the timer set to 0, the call is transmitted automatically when the user dials the final digit in the sequence.

Secure Call Implementation

This section describes secure call implementation with the SRP. It includes the following sections:

• Enabling Secure Calls
• Secure Call Details
• Using a Mini-Certificate
• Generating a Mini Certificate

NOTE This is an advanced topic only meant for experienced installers.

Enabling Secure Calls

A secure call is established in two stages. The first stage is no different from normal call setup. The second stage starts after the call is established in the normal way with both sides ready to stream RTP packets.

In the second stage, the two parties exchange information to determine if the current call can switch over to the secure mode. The information is transported by base64 encoding embedded in the message body of SIP INFO requests, and responses using a proprietary format. If the second stage is successful, the SRP plays a special Secure Call Indication Tone for a short time to indicate to both parties that the call is secured and that RTP traffic in both directions is being encrypted.

If the user has a phone that supports Call Waiting Caller ID (CIDCW) and that service is enabled, the CID will be updated with the information extracted from the Mini-Certificate received from the remote party. The Name field of the CID will be prepended with a \$' symbol. Both parties can verify the name and number to ensure the identity of the remote party.

The signing agent is implicit and must be the same for all devices that communicate securely with each other. The public key of the signing agent is pre-configured into the SRP by the administrator and is used by the SRP to verify the Mini-Certificate of its peer. The Mini-Certificate is valid if it has not expired, and it has a valid signature.

The SRP can be configured so that, by default, all outbound calls are either secure or not secure. If secure by default, the user has the option to disable security when making a call by dialing *19 before dialing the target number. If not secure by default, the user can make a secure outbound call by dialing *18 before dialing the target number. However, the user cannot force inbound calls to be secure or not secure; that depends on whether the caller has security enabled or not.

The SRP will not switch to secure mode if the CID of the called party from its Mini-Certificate does not agree with the user-id used in making the outbound call. The SRP performs this check after receiving the Mini-Certificate of the called party.

Secure Call Details

Looking at the second stage of setting up a secure call in greater detail, this stage can be further divided into two steps.

STEP 1 The caller sends a "Caller Hello" message (base64 encoded and embedded in the message body of a SIP INFO request) to the called party with the following information:

• Message ID (4B)
• Version and flags (4B)
• SSRC of the encrypted stream (4B)
• Mini-Certificate (252B)

Upon receiving the Caller Hello, the called party responds with a Callee Hello message (base64 encoded and embedded in the message body of a SIP response to the caller's INFO request) with similar information, if the Caller Hello message is valid. The caller then examines the Callee Hello and proceeds to the next step if the message is valid.

STEP 2 The caller sends the "Caller Final" message to the called party with the following information:

• Message ID (4B)
• Encrypted Master Key (16B or 128b)

- Encrypted Master Salt (16B or 128b)

Using a Mini-Certificate

The Master Key and Master Salt are encrypted with the public key from the called party mini-certificate. The Master Key and Master Salt are used by both ends for deriving session keys to encrypt subsequent RTP packets. The called party then responds with a Callee Final message (which is an empty message).

The Mini-Certificate (MC) contains the following information:

• User Name (32B)
• User ID or Phone Number (16B)
• Expiration Date (12B)
• Public Key (512b or 64B)
• Signature (1024b or 512B)

The MC has a 512-bit public key used for establishing secure calls. The administrator must provision each subscriber of the secure call service with an MC and the corresponding 512-bit private key. The MC is signed with a 1024-bit private key of the service provider, which acts as the Certificate Authority (CA) of the MC. The 1024-bit public key of the CA signing the MC must also be provisioned for each subscriber.

The CA public key is used to verify the MC received from the other end. If the MC is invalid, the call will not switch to secure mode. The MC and the 1024-bit CA public key are concatenated and base64 encoded into the single parameter Mini Certificate. The 512-bit private key is base64 encoded into the SRTP Private Key parameter, which should be kept secret, like a password. (Mini Certificate and SRTP Private Key are configured in the Line pages (1-4).

Because the secure call establishment relies on exchange of information embedded in message bodies of SIP INFO requests/responses, the service provider must ensure that the network infrastructure allows the SIP INFO messages to pass through with the message body unmodified.

Generating a Mini Certificate

Cisco provides a Mini Certificate Generator for the generation of mini certificates and private keys. Contact your Cisco representative to access this tool.

The Mini Certificate Generator uses the following syntax:

gen_mc ca-key user-name user-id expire-date

Where:

- ca-key is a text file with the base64 encoded 1024-bit CA private/public key pairs for signing/verifying the MC, such as the following:

9CC9aYU1X51JuU+EBZmi3AmcqE9U1LxEOGwopaGyGOn3VyhKgi6JaVtQZt87PiJINKW8XQj3B9Qqe3VgYxWCQNa335YCnDsenASeBxuMIEaBCYd1l1fVEodJZOGwXwfAde0MhcbD0kj7LVlzcsTyk2TZYTccnZ75TuTjj13qvYs=5nEtOrkCa84/mEwl3D9tSvVLyliwQ+u/

• user-name is the name of the subscriber, such as "Joe Smith". Maximum length is 32 characters.
• user-id is the User ID of the subscriber, which must match exactly the userid used in the INVITE when making the call, such as “14083331234”. The maximum length is 16 characters.
• expire-date is the expiration date of the MC, such as "00:00:00 1/1/34" 34=2034). Internally the date is encoded as a fixed 12B string: 000000010134

The tool generates the Mini Certificate and SRTP Private Key parameters that can be provisioned.

Example:

gen_mc ca_key "Joe Smith" 14085551234 "00:00:00 1/1/34" 

This example produces the following Mini Certificate and SRTP Private Key:

Reg Retry Intvl Interval to wait before the SRP retries registration after failing during the last registration.The default is 30.
Reg Retry Long Intvl When registration fails with a SIP response code that does not match Retry Reg RSC, the SRP waits for the specified length of time before retrying. If this interval is 0, the SRP stops trying. This value should be much larger than the Reg Retry Intvl value, which should not be 0.The default is 1200

Response Status Code Handling

Voice > SIP > Response Status Code Handling

SIT1 RSC SIP response status code for the appropriateSpecial Information Tone (SIT). For example, if you set the SIT1 RSC to 404, when the user makes a call and a failure code of 404 is returned, the SIT1 tone is played. Reorder or Busy tone is played by default for all unsuccessful response status code for SIT 1 RSC through SIT 4 RSC.

SIT2 RSC SIP response status code to INVITE on which to play the SIT2 Tone.

SIT3 RSC SIP response status code to INVITE on which to play the SIT3 Tone.

SIT4 RSC SIP response status code to INVITE on which to play the SIT4 Tone.

Try Backup RSC SIP response code that retries a backup server for the current request

Retry Reg RSC Interval to wait before the SRP retries registration after failing during the last registration.

RTP Parameters

Voice > SIP > RTP Parameters

RTP Port Min Minimum port	number for RTP transmission and reception.The RTP Port Min and RTP Port Max parameters should define a range that contains at least 4 even number ports, such as 100 –106.The default is 16384.
RTP Port Max Maximum port	number for RTP transmission and reception.The default is 16482.
RTP Packet Size Packet size in seconds, which can range from 0.01 to 0.16. Valid values must be a multiple of 0.01 seconds. The default is 0.030.
Max RTP ICMP Err Number of successive ICMP errors allowed when transmitting RTP packets to the peer before the SRP terminates the call. If value is set to 0, the SRP ignores the limit on ICMP errors. The default is 0.
RTCP Tx Interval Interval for sending out RTCP sender reports on an active connection. It can range from 0 to 255 seconds. During an active connection, the SRP can be programmed to send out compound RTCP packet on the connection. Each compound RTP packet except the last one contains a SR (Sender Report) and a SDES.(Source Description). The last RTCP packet contains an additional BYE packet. Each SR except the last one contains exactly 1 RR (Receiver Report); the last SR carries no RR. The SDES contains CNAME, NAME, and TOOL identifiers. The CNAME is set to@<Proxy>, NAME is set to <Display Name> (or Anonymous if user blocks caller ID), and TOOL is set to the Vendor/Hardware-platform-software-version (such as Cisco/srp5201.0.31(b)). The NTP timestamp used in the SR is a snapshot of the SRP's local time, not the time reported by an NTP server. If the SRP receives a RR from the peer, it attempts to compute the round trip delay and show it as thevalue (ms) on the Voice > Info page. The default is 0.
No UDP Checksum Select yes if you want the SRP to calculate the UDP header checksum for SIP messages. Otherwise, select no. The default is no.
Stats In BYE Determines wh	ether the SRP includes the P-RTP-Stat header or response in a BYE message. The header contains the RTP statistics of the current call. Select yes or no from the drop-down list. The format of the P-RTP-Stat header is:P-RTP-State: PS=,OS=,PR=,OR=,PL=,JL=,LA=,DU=,EN=,DE=.The default is yes.

Insert VIA received Inserts the received parameter into the VIA header of SIP responses if the received-from IP and VIA sent-by IP values differ. Select yes or no from the drop-down menu.The default is no.

Insert VIA rport Inserts the parameter into the VIA header of SIP responses if the received-from IP and VIA sent-by IP values differ. Select yes or no from the drop-down menu.The default is no.

Substitute VIA Addr Lets you use NAT-mapped IP:port values in the VIA header. Select yes or no from the drop-down menu.The default is no.

Send Resp To Src Port Sends responses to the request source port instead of the VIA sent-by port. Select yes or no from the drop-down menu.The default is no.

STUN Enable Enables the use of STUN to discover NAT mapping. Select yes or no from the drop-down menu.The default is no.

STUN Test Enable If the STUN Enable feature is enabled and a valid STUN server is available, the SRP can perform a NAT-type discovery operation when it powers on. It contacts the configured STUN server, and the result of the discovery is reported in a Warning header in all subsequent REGISTER requests. If the SRP detects symmetric NAT or a symmetric firewall, NAT mapping is disabled.The default is no.

STUN Server IP address	or fully-qualified domain name of the STUN server to contact for NAT mapping discovery.
EXT IP External IP address	to substitute for the actual IPaddress of the SRP in all outgoing SIP messages. If 0.0.0.0 is specified, no IP address substitution is performed.If this parameter is specified, the SRP assumes this IP address when generating SIP messages and SDP (if NAT Mapping is enabled for that line). However, the results of STUN and VIA received parameter processing, if available, supersede this statically configured value.NOTE: This option requires that you have (1) a static IP address from your Internet Service Provider and (2) an edge device with a symmetric NAT mechanism. If the SRP is the edge device, the second requirement is met.The default is 0.0.0.0.
EXT RTP Port Min External	port mapping number of the RTP Port Min.number. If this value is not zero, the RTP port number in all outgoing SIP messages is substituted for the corresponding port value in the external RTP port range.There is no default value.
NAT Keep Alive Intvl Interval	between NAT-mapping keep alive messages.The default is 15.

Provisioning Page

Use the Provisioning page to configure various profiles and parameters. This page includes the following sections:

• Configuration Profile
• Firmware Upgrade
• General Purpose Parameters

Configuration Profile

Voice > Provisioning > Configuration Profile

Provision Enable Controls all resync actions independently of firmware upgrade actions. Set to Yes to enable remote provisioning.The default is Yes.
Resync On Reset Triggers a resync after every reboot except for reboots caused by parameter updates and firmware upgrades.The default is Yes.
Resync Random Delay	The maximum value for a random time interval that the device waits before making its initial contact with the provisioning server. This delay is effective only on the initial configuration attempt following device power-on or reset. The delay is a pseudo-random number between zero and this value.This parameter is in units of 20 seconds; the default value of 2 represents 40 seconds. This feature is disabled when this parameter is set to zero.This feature can be used to prevent an overload of the provisioning server when a large number of devices power-on simultaneously.The default is 2 (40 seconds).
Resync Periodic The	time interval between periodic resyncs with the provisioning server. The associated resync timer is active only after the first successful sync with the server. Set this parameter to zero to disable periodic resyncing. The default is 3600 seconds.
Resync Error Retry Delay	Resync retry interval (in seconds) applied in case of resync failure.The device has an error retry timer that activates if the previous attempt to sync with the provisioning server fails. The device waits to contact the server again until the timer counts down to zero.This parameter is the value that is initially loaded into the error retry timer. If this parameter is set to zero, the device immediately retries to sync with the provisioning server following a failed attempt.The default is 3600 seconds.
Forced Resync Delay	Maximum delay (in seconds) the SPA waits before performing a resync.The device does not resync while one of its phone lines is active. Because a resync can take several seconds, it is desirable to wait until the device has been idle for an extended period before resyncing. This allows a user to make calls in succession without interruption.The device has a timer that begins counting down when all of its lines become idle. This parameter is the initial value of the counter. Resync events are delayed until this counter decrements to zero.The default is 14,400 seconds.
Resync From SIP Enables a resync to be triggered via a SIP NOTIFY message.The default is Yes.
Resync After Upgrade Attempt	Triggers a resync after every firmware upgrade attempt. The default is Yes.
Resync Trigger 1Resync Trigger 2	Configurable resync trigger conditions. A resync is triggered when the logic equation in these parameters evaluates to TRUE.The default is (empty).
Resync Fails On FNF	Determines whether a file-not-found response from the provisioning server constitutes a successful or a failed resync. A failed resync activates the error resync timer.The default is Yes.
Profile Rule This parameter is a profile script that evaluates to the provisioning resync command. The command is a TCP/IP operation and an associated URL. The TCP/IP operation can be TFTP, HTTP, or HTTPS.If the command is not specified, TFTP is assumed, and the address of the TFTP server is obtained through DHCP option 66. In the URL, either the IP address or the FQDN of the server can be specified. The file name can have macros, such as MA, which expands to the device MAC address.The default is /srpPSN.cfg.
Profile Rule B:Profile Rule C:Profile Rule D:	Defines second, third, and fourth resync commands and associated profile URLs. These profile scripts are executed sequentially after the primary Profile Rule resync operation has completed. If a resync is triggered and Profile Rule is blank, Profile Rule B, C, and D are still evaluated and executed.The default is (empty).
Profile Name and Profile Region	A provisioning server can store string data in this parameter, and subsequently read this data back when querying the device. It performs no other internal function.
Log Resync Request Msg	This parameter contains the message that is sent to the Syslog server at the start of a resync attempt.The default is PNMAC – Requesting resync SCHEME://SERVIP:PORTPATH.
Log ResyncSuccess Msg	Syslog message issued upon successful completion of a resync attempt.The default is PNMAC – Successful resyncSCHEME://SERVIP:PORTPATH -- ERR.
Log Resync FailureMsg	Syslog message issued after a failed resync attempt.The default isPN MAC – Resync failed:ERR.
Report Rule The target	URL to which configuration reports are sent.This parameter has the same syntax as the Profile_Rule parameter, and resolves to a TCP/IP command with an associated URL.A configuration report is generated in response to an authenticated SIP NOTIFY message, with Event: report.The report is an XML file containing the name and value of all the device parameters.This parameter may optionally contain an encryption key.For example:[ --key K ] tftp://ps.callhome.net/MA/rep.xml.encThe default is (empty).

Firmware Upgrade

Voice > Provisioning > Firmware Upgrade

Upgrade Enable Enables firmware upgrade operations independently of resync actions.The default is Yes.
Upgrade Error Retry Delay	The upgrade retry interval (in seconds) applied in case of upgrade failure. The device has a firmware upgrade error timer that activates after a failed firmware upgrade attempt. The timer is initialized with the value in this parameter. The next firmware upgrade attempt occurs when this timer counts down to zero.The default is 3600 seconds.
Downgrade Rev Limit	Enforces a lower limit on the acceptable version number during a firmware upgrade or downgrade. The device does not complete a firmware upgrade operation unless the firmware version is greater than or equal to this parameter.The default is (empty).
Upgrade Rule This pa	parameter is a firmware upgrade script with the same syntax as Profile_Rule. Defines upgrade conditions and associated firmware URLs.The default is (empty).
Log Upgrade Request Msg	Syslog message issued at the start of a firmware upgrade attempt.The default is PNMAC -- Requesting upgrade SCHEME://SERVIP:PORTPATH.
Log Upgrade Success Msg	Syslog message issued after a firmware upgrade attempt completes successfully.The default is PNMAC -- Successful upgrade SCHEME://SERVIP:PORTPATH -- ERR.
Log Upgrade Failure Msg	Syslog message issued after a failed firmware upgrade attempt.The default isPN MAC -- Upgrade failed:ERR.
License Keys This field	is not currently used by the SRP500.

Defining Ring and Cadence and Tone Scripts

To define ring and tone patterns, the SRP uses the concept of scripts. The following defines how to create Cadence Scripts (CadScripts), Frequency Scripts (FreqScripts) and Tone Scripts (ToneScripts).

CadScript

A mini-script of up to 127 characters that specifies the cadence parameters of a signal.

Syntax: S_1 ; S_2 ], where:

S_i=D_i(on_i,1/off_i,1[,on_i,2/off_i,2[,on_i,3/off_i,3[,on_i,4/off_i,4[,on_i,5/off_i,5,on_i,6/off_i,6]]]) and is known as a section, on_i,j and off_i,j are the on/off duration in seconds of a segment and i=1 or 2, and j=1 to 6. D_i is the total duration of the section in seconds. All durations can have up to three decimal places to provide 1 ms resolution. The wildcard character “*” represents infinite duration. The segments within a section are played in order and repeated until the total duration is played.

Example 1: 60(2/4)

Number of Cadence Sections = 1 Cadence Section 1: Section Length = 60 s Number of Segments = 1

Segment 1: On=2s, Off=4s
Total Ring Length = 60s 

Example 2—Distinctive ring (short, short, short, long): 60(.2/.2,.2/.2,.2/.2,1/4)

Number of Cadence Sections = 1
Cadence Section 1: Section Length = 60s
Number of Segments = 4
Segment 1: On=0.2s, Off=0.2s
Segment 2: On=0.2s, Off=0.2s
Segment 3: On=0.2s, Off=0.2s
Segment 4: On=1.0s, Off=4.0s
Total Ring Length = 60s 

FreqScript

A mini-script of up to 127 characters that specifics the frequency and level parameters of a tone.

Syntax: F_1@L_1[,F_2@L_2[,F_3@L_3[,F_4@L_4[,F_5@L_5[,F_6@L_6]]]]

Where F_1-F_6 are frequency in Hz (unsigned integers only) and L_1-L_6 are corresponding levels in dBm (with up to 1 decimal places). White spaces before and after the comma are allowed (but not recommended).

Example 1—Call Waiting Tone: 440@-10

Number of Frequencies = 1
Frequency 1 = 440 Hz at -10 dBm 

Example 2—Dial Tone: 350@-19,440@-19

Number of Frequencies = 2
Frequency 1 = 350 Hz at -19 dBm
Frequency 2 = 440 Hz at -19 dBm 

ToneScript

A mini-script of up to 127 characters that specifies the frequency, level and cadence parameters of a call progress tone. May contain up to 127 characters.

Syntax: FreqScript;Z 1 ;Z 2 ].

The section Z_1 is similar to the S_1 section in a CadScript except that each on/off segment is followed by a frequency components parameter: Z_1 = D_1(on_i,1/off_i,1/f_i,1[on_i,2/off_i,2/f_i,2[on_i,3/off_i,3/f_i,3[on_i,4/off_i,4/f_i,4[on_i,5/off_i,5/f_i,5[on_i,6/off_i,6/f_i,6]]]) , where fi,j = n_1[+n_2] + n_3[+n_4[+n_5[+n_6]] and 1 < n_k < 6 indicates which of the frequency components given in the FreqScript are used in that segment; if more than one frequency component is used in a segment, the components are summed together.

Example 1—Dial tone: 350@-19,440@-19;10(*/0/1+2)

Number of Frequencies = 2
Frequency 1 = 350 Hz at -19 dBm
Frequency 2 = 440 Hz at -19 dBm
Number of Cadence Sections = 1
Cadence Section 1: Section Length = 10 s
Number of Segments = 1
Segment 1: On=forever, with Frequencies 1 and 2
Total Tone Length = 10s 

Example 2—Stutter tone: 350@-19,440@-19;2(.1/.1/1+2);10(*/0/1+2)

Number of Frequencies = 2
Frequency 1 = 350 Hz at -19 dBm
Frequency 2 = 440 Hz at -19 dBm
Number of Cadence Sections = 2
Cadence Section 1: Section Length = 2s
Number of Segments = 1
Segment 1: On=0.1s, Off=0.1s with Frequencies 1 and 2
Cadence Section 2: Section Length = 10s
Number of Segments = 1
Segment 1: On=forever, with Frequencies 1 and 2
Total Tone Length = 12s

Ring and Call Waiting Tone Spec

IMPORTANT: Ring and Call Waiting tones do not work the same way on all phones. When setting ring tones, consider the following recommendations:

• Begin with the default Ring Waveform, Ring Frequency, and Ring Voltage.
• If your ring cadence doesn't sound right, or your phone doesn't ring, change your Ring Waveform, Ring Frequency, and Ring Voltage to the following:

- Ring Waveform: Sinusoid

- Ring Frequency: 25

- Ring Voltage: 80Vc

Ring Waveform	Waveform for the ringing signal. Choices are Sinusoid or Trapezoid.The default is Trapezoid.
Ring Frequency F	frequency of the ringing signal. Valid values are 10–100 (Hz). The default is 20.
Ring Voltage Ringing voltage. Choices are 60–90 (V).The default is 85.
CWT Frequency F	frequency script of the call waiting tone. All distinctive CWTs are based on this tone.The default is 440@-10.
Synchronized Ring	If this is set to Yes, when the SRP is called, all lines ring at the same time (similar to a regular PSTN line). After one line answers, the others stop ringing.The default is no.

Control Timer Values (sec)

Voice > Regional > Control Timer Values (sec)

Hook Flash Timer Min	Minimum on-hook time before off-hook qualifies as hookflash. Less than this the on-hook event is ignored. Range: 0.1–0.4 seconds.The default is 0.1.
Hook Flash Timer Max	Maximum on-hook time before off-hook qualifies as hookflash. More than this the on-hook event is treated as onhook (no hook-flash event). Range: 0.4–1.6 seconds.The default is 0.9.
Callee On Hook Delay	Phone must be on-hook for at this time in sec. before the SRP will tear down the current inbound call. It does not apply to outbound calls. Range: 0–255 seconds.The default is 0.
Reorder Delay Delay after far end hangs up before reorder tone is played. 0 = plays immediately, inf = never plays. Range: 0–255 seconds.The default is 5.
Call Back Expires Expiration time in seconds of a call back activation.Range: 0–65535 seconds.The default is 1800.
Call Back Retry Intvl Call back retry interval in seconds. Range: 0–255 seconds.The default is 30.
Call Back Delay Delay after receiving the first SIP 18x response before declaring the remote end is ringing. If a busy response is received during this time, the SRP still considers the call as failed and keeps on retrying.The default is 0.5.
VMWI Refresh Intvl Interval between VMWI refresh to the CPE.The default is 0.
Interdigit Long Timer Long timeout between entering digits when dialing. The interdigit timer values are used as defaults when dialing. The Interdigit_Long_Timer is used after any one digit, if all valid matching sequences in the dial plan are incomplete as dialed. Range: 0–64 seconds.The default is 10.
Interdigit Short Timer	Short timeout between entering digits when dialing. The Interdigit_Short_Timer is used after any one digit, if at least one matching sequence is complete as dialed, but more dialed digits would match other as yet incomplete sequences. Range: 0–64 seconds.The default is 3.
CPC Delay Delay in sec	conds after caller hangs up when the SRP starts removing the tip-and-ring voltage to the attached equipment of the called party. The range is : 0–255 seconds. This feature is generally used for answer supervision on the caller side to signal to the attached equipment when the call has been connected (remote end has answered) or disconnected (remote end has hung up). This feature should be disabled for the called party (in other words, by using the same polarity for connected and idle state) and the CPC feature should be used instead.Without CPC enabled, reorder tone will is played after a configurable delay. If CPC is enabled, dial tone will be played when tip-to-ring voltage is restored. Resolution is 1 second.The default range is 2.
CPC Duration Duration	in seconds for which the tip-to-ring voltage is removed after the caller hangs up. After that, tip-to-ring voltage is restored and dial tone applies if the attached equipment is still off-hook. CPC is disabled if this value is set to 0. Range: 0 to 1.000 second. Resolution is 0.001 second.The default is 0 (CPC disabled).

Secure One Call Deact Code	Makes the next outbound call not secure. (It is redundant if all outbound calls are not secure by default.)The default is *19.
Conference Act Code	If this code is specified, the user must enter it before dialing the third party for a conference call. Enter the code for a conference call.
Attn-Xfer Act Code If the code is specified, the user must enter it before dialing the third party for a call transfer. Enter the code for a call transfer.
Modem Line Toggle Code	Toggles the line to a modem. The default is *99. Modem pass-through mode can be triggered only by pre-dialing this code.
FAX Line Toggle Code	Toggles the line to a fax machine.The default is #99.
Media Loopback Code	Use for media loopback.The default is *03.
Referral Services Codes	These codes tell the SRP what to do when the user places the current call on hold and is listening to the second dial tone.One or more *code can be configured into this parameter, such as *98, or *97l*98l*123, etc. Max total length is 79 chars. This parameter applies when the user places the current call on hold (by Hook Flash) and is listening to second dial tone. Each *code (and the following valid target number according to current dial plan) entered on the second dial-tone triggers the SRP to perform a blind transfer to a target number that is prepended by the service *code.For example, after the user dials *98, the SRP plays a special dial tone called the Prompt Tone while waiting for the user the enter a target number (which is checked according to dial plan as in normal dialing). When a complete number is entered, the SRP sends a blind REFER to the holding party with the Refer-To target equals to *98 target_number. This feature allows the SRP to hand off a call to an application server to perform further processing, such as call park.The *codes should not conflict with any of the other vertical service codes internally processed by the SRP. You can empty the corresponding *code that you do not want the SRP to process.
Feature DialServices Codes	These codes tell the SRP what to do when the user is listening to the first or second dial tone.One or more *code can be configured into this parameter, such as *72, or *72|*74|*67|*82, etc. Max total length is 79 chars. This parameter applies when the user has a dial tone (first or second dial tone). Enter *code (and the following target number according to current dial plan) entered at the dial tone triggers the SRP to call the target number prepended by the *code. For example, after user dials *72, the SRP plays a special tone called a Prompt tone while awaiting the user to enter a valid target number. When a complete number is entered, the SRP sends a INVITE to *72 target_number as in a normal call. This feature allows the proxy to process features like call forward (*72) or Block Caller ID (*67).The *codes should not conflict with any of the other vertical service codes internally processed by the SRP. You can empty the corresponding *code that you do not want to the SRP to process.You can add a parameter to each *code in Features Dial Services Codes to indicate what tone to play after the *code is entered, such as *72'c'l*67'p'. Below are a list of allowed tone parameters (note the use of open quotes surrounding the parameter w/o spaces)'c' =
	'd' =
	'm' =
	'o' =
	'p' =
	's' =
	'x' = No tones are place, x is any digit not used aboveIf no tone parameter is specified, the SRP plays Prompt tone by default. If the *code is not to be followed by a phone number, such as *73 to cancel call forwarding, do not include it in this parameter. In that case, simply add that *code in the dial plan and the SRP send INVITE *73@..... as usual when user dials *73.

• Line Enable
• Streaming Audio Server (SAS)
• NAT Settings
• Network Settings
• SIP Settings
• Call Feature Settings
• Proxy and Registration
• Outbound Proxy SIP
  • Supplementary Service Subscription
• Audio Configuration
• Dial Plan

In a configuration profile, the Line parameters must be appended with the appropriate numeral (for example, [1] or [2]) to identify the line to which the setting applies.

Line Enable

Voice > Line 1-2 > Line Enable

Line Enable To enable this line for service, select yes. Otherwise, select no.The default is yes.

Streaming Audio Server (SAS)

Voice > Line 1-2 > Streaming Audio Server (SAS)

SAS Enable To enable the use of the line as a streaming audio source, select yes. Otherwise, select no. If enabled, the line cannot be used for outgoing calls. Instead, it auto-answers incoming calls and streams audio RTP packets to the caller.The default is no.

SAS DLG Refresh Intvl If this value is not zero, it is the interval at which the streaming audio server sends out session refresh (SIP re-INVITE) messages to determine whether the connection to the caller is still active. If the caller does not respond to the refresh message, the SRP ends this call with a SIP BYE message. The range is 0 to 255 seconds (0 means that the session refresh is disabled).The default is 30.

SAS Inbound RTP Sink This

setting works around devices that do not play inbound RTP if the streaming audio server line declares itself as a send-only device and tells the client not to stream out audio. Enter a Fully Qualified Domain Name (FQDN) or IP address of an RTP sink; this value is used by the streaming audio server line in the SDP of its 200 response to an inbound INVITE message from a client.The purpose of this parameter is to work around devices that do not play inbound RTP if the SAS line declares itself as a send-only device and tells the client not to stream out audio. This parameter is a FQDN or IP address of a RTP sink to be used by the SAS line in the SDP of its 200 response to inbound INVITE from a client. It will appear in the c = line and the port number and, if specified, in the m = line of the SDP. If this value is not specified or equal to 0, then c = 0.0.0.0 and a=sendonly will be used in the SDP to tell the SAS client to not to send any RTP to this SAS line. If a non-zero value is specified, then a=sendrecv and the SAS client will stream audio to the given address. Special case: If the value is $IP, then the SAS line's own IP address is used in the c = line and a=sendrecv. In that case the SAS client will stream RTP packets to the SAS line.The default value is empty.

The minimum jitter buffer size is 30 milliseconds or (10 milliseconds + current RTP frame size), whichever is larger, for all jitter level settings. However, the starting jitter buffer size value is larger for higher jitter levels. This setting controls the rate at which the jitter buffer size is adjusted to reach the minimum. Select the appropriate setting: low, medium, high, very high, or extremely high.The default is high.
Jitter Buffer Adjustment Controls how the jitter buffer should be adjusted. Select the appropriate setting: up and down, up only, down only, or disable.The default is up and down.

SIP Settings

Voice > Line 1-2 > SIP Settings

SIP Transport The TCP choice provides “guaranteed delivery”, which assures that lost packets are retransmitted. TCP also guarantees that the SIP packages are received in the same order that they were sent. As a result, TCP overcomes the main disadvantages of UDP. In addition, for security reasons, most corporate firewalls block UDP ports. With TCP, new ports do not need to be opened or packets dropped, because TCP is already in use for basic activities such as Internet browsing or e-commerce. Options are: UDP, TCP, TLS.The default is UDP.

SIP GUID The Global Unique ID is generated for each line for each device. When it is enabled, the SRP adds a GUID header in the SIP request. The GUID is generated the first time the unit boots up and stays with the unit through rebooting and even factory reset. This feature was requested by Bell Canada (Nortel) to limit the registration of SIP accounts.The default is no.
SIP Debug Option SIP messages are received at or sent from the proxy listen port. This feature controls which SIP messages to log.Choices are as follows:none—No logging.1-line—Logs the start-line only for all messages.1-line excl. OPT—Logs the start-line only for all messages except OPTIONS requests/responses.1-line excl. NTFY—Logs the start-line only for all messages except NOTIFY requests/responses.1-line excl.

IKE Policy Settings
Field Description
General
Policy Name Enter a unique name for the VPN policy.
Exchange Mode	Choose the exchange mode based on your requirements for security and speed.Main: Choose this mode if you want higher security, but with a slower connection. Main Mode relies upon two-way key exchanges between the initiator and the receiver. The key-exchange process slows down the connection but increases security.Aggressive: Choose this mode if you want a faster connection, but with lowered security. In Aggressive Mode there are fewer key exchanges between the initiator and the receiver. Both sides exchange information even before there is a secure channel.
IKE SA Parameters
Encryption Algorithm	Choose an encryption mode. Select from DES, 3DES, AES128, AES192, and AES256.
Authentication Algorithm	Choose an authentication algorithm for the IKA SA. Select from MD5 and SHA1.
