To finish the call, press o ⑤ the handset in the base or the charger unit.

Note:

• You can switch off the ringer temporarily by pressing Silent Soft key.
• When you receive a call the Handset will automatically sync up the date and time from the base station.
  Due to the channel limitation, DP715 can support at most 4 simutianous calls at the same time. If using PBX ring group function to ring 5 different accounts for 5 handsets, the 5^th handset will not ring. Please use DP715 hunting group function instead.

INTERNAL CALLS

In some cases a user may want to make phone calls between the handsets registered to the same DP715 Base Station when it is used as a standalone unit, without the use of a SIP server. This feature will also be applicable when the DP715 Base Station is used with Hunting Groups and is registered to SIP server only with one master number. In such cases users still will be able to make internal calls by following these steps:

1. Press INT.
2. Internal appears in the display.
3. Select the number of the handset (keys 1-5) you wish to call.
4. When you have completed your call, press 5 up.

Note: Both Handsets should be registered to the same DP715 Base station.

DIRECT IP CALLS

Direct IP calling allows two parties, that is, a Handset and another VoIP Device, to talk to each other in an ad hoc fashion without a SIP proxy.

Elements necessary to complete a Direct IP Call:

1. Both DP715 and other VoIP Device, have public IP addresses, or
2. Both DP715 and other VoIP Device are on the same LAN using private IP addresses, or
3. Both DP715 and other VoIP Device can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ).

DP715 supports two ways to make Direct IP Calling:

Using IVR

1. Pick up the Handset and press (11) then access the voice menu prompt by dial “***”
2. Dial "47" to access the direct IP call menu
3. Enter the IP address after the dial tone and voice prompt "Direct IP Calling"

Using Star Code

1. Pick up the Handset and press t (11) al "*47"
2. Enter the target IP address.

Note: NO dial tone will be played between step 1 and 2.

Examples of Direct IP Calls:

a) If the target IP address is 192.168.0.160, the dialing convention is *47 or Voice Prompt with option 47, then 192*168*0*160. followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case, the default destination port 5060 is used if no port is specified.
b) If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be: *47 or Voice Prompt with option 47, then 192*168*0*160*5062 followed by pressing the “#” key if it is configured as a send key or wait for 4 seconds.

Note: When completing direct IP call, the "Use Random Port" should set to "NO".

CALL HOLD

Place a call on hold by pressing the "Recall" button on the Handset. Press the "Recall" button again to release the previously held Caller and resume conversation.

CALL WAITING

Call waiting tone (3 short beeps) indicates an incoming call, if the call waiting feature is enabled. Toggle between incoming call and current call by pressing the "Recall" button. First call is placed on hold. Press the "Recall" button to toggle between two active calls.

CALL TRANSFER

Blind Transfer

This function is applicable using the Handset for VoIP calls only. Assume that parties A and B are in conversation. PartyA wants to Blind TransferB to C:

1. A presses RECALL on the Handset to hear the dial tone.
2. A dials *87 then dials caller C's number, and then # (or wait for 4 seconds)
3. A will hear the confirmation tone. Then, A can hang up.

Note: "Enable Call Feature" must be set to "Yes" in web configuration page.

Threesituations can follow the transfer:

a. A quick confirmation tone (similar to call waiting tone) followed by a dial-tone: This indicates the transfer is successful (transferee has received a 200 OK from transfer target). At this point, Caller A can either hang up or make another call.

b. A quick busy tone followed by a restored call (on supported platforms only): This means the transferee has received a 4xx response for the INVITE and we will try to recover the call. The busy tone is just to indicate to the transferor that the transfer has failed.

c. Continuous busy tone: The phone has timed out.

Note: continuous busy tone does not indicate the transfer has been successful, nor does it indicate the transfer has failed. It often means there was a failure to receive second NOTIFY – check firmware for most recent release.

Attended Transfer

This function is applicable using the Handset for VoIP calls only. Assume that parties A and B are in conversation. PartyA wants to Attend TransferB to C:

1. A presses RECALL on the Handset for dial tone.
2. A then dials Caller C's number followed by # (or wait for 4 seconds).
3. If C answers the call, A and C are in conversation. Then A can hang up to complete transfer.
4. If C does not answer the call, A can press "flash" to resume call with Caller B.

Note: When Attended Transfer fails and A hangs up, the DP715 will ring back user A to remind A that B is still on the call. A can pick up the phone to resume conversation with B.

3-WAY CONFERENCING

The DP715 supports Bellcore style 3-way Conference.

Instructions for 3-way conference:

Assume that partiesA and B are in conversation. PartyA wants to bring C into a 3-way conference:

1. A presses RECALL (on the Handset) to get a dial tone.
2. A dials C's number then # (or wait for 4 seconds).
3. If C answers the call, then A presses RECALL to bring B. C in the conference.
4. If C does not answer the call. A can press RECALL back to talk to B.
5. If A presses RECALL during conference, C will be dropped out.
6. If A hangs up, the conference will be terminated for all three parties when configuration "Transfer on Conference Hang up" is set to "No". If the configuration is set to "Yes", A will transfer B to C so that B and C can continue the conversation.

FIRMWARE UPGRADE MODE

Select voice menu option 17 to choose firmware upgrade mode among the following three options: 1) Always check, 2) check when pre/suffix changes, and 3) never upgrade.

CONFIGURING THE BASE STATION VIA WEB BROWSER

DP715 Base Station has an embedded Web server that will respond to HTTP GET/POST requests. It also has embedded HTML pages that allow users to configure the DP715 through a web browser such as Microsoft's IE, AOL's Netscape or Mozilla Firefox installed on Windows or Unix OS. (Macintosh OS is not included).

Access the Web Configuration Menu

1. Find the IP address of the Base Station using voice prompt menu option 02.
2. Open a web browser, type in the IP address. You will see the login page of the device.

Once the HTTP request is entered and sent from a web browser, the user will see a login screen. There are two default passwords for the login page:

User Level:	Password:	Web pages allowed:
End User Level	123	Only Status and Basic Settings
Administrator Level	admin	Browse all pages

The password is case sensitive with maximum length of 25 characters. The factory default password for End User and administrator is "123" and "admin" respectively. Only an administrator can access the "ADVANCED SETTINGS", "HANDSET SETTINGS" and "PROFILE SETTINGS" configuration pages.

Please refer to the GUI pages using the following link: http://www.grandstream.com/products/dp_series/dp71x/documents/dp715_gui.zip.

Note: If you cannot log into the configuration page by using the default password, please check with the VoIP service provider. It is most likely the VoIP service provider has provisioned the device and configured for you therefore the password has already been changed.

IMPORTANT SETTINGS

The end-user must configure the following settings according to the local environment. Note: Most settings on the web configuration pages are set to the default values.

NAT Settings

If you plan to keep the DP715 Base Station within a private network behind a firewall, we recommend using STUN Server. The following three (3) settings are useful in the STUN Server scenario:

1. STUN Server (under Advanced Settings webpage) Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the internet and enter it on this field. If using Public IP, keep this field blank.

2. Use Random Port (under Profile Settings webpage) This setting depends on your network settings. Generally if you have multiple IP devices under the same network, it should be set to Yes. If using a Public IP address, set this parameter to No.

3. NAT Traversal (under the Profile web page) Set this to Yes when gateway is behind firewall on a private network.

DTMF Methods

DTMF Settings are in ProfileX page.

• DTMF in-audio
  • DTMF via RTP (RFC2833)
• DTMF via SIP INFO

Set priority of DTMF methods according to your preference. This setting should be based on your server DTMF setting.

Preferred VOCODER (Codec)

The DP715 supports a broad range of voice codecs. Under Profile web pages, choose your preferred order of different codecs:

G711a/u
G729AB
G723.1
iLBC

Basic Configuration
Profile Active	When set to Yes the Profile is activated.
Primary SIP Server	SIP Server's IP address or Domain name provided by VoIP service provider.
Failover SIP Server	Failover SIP Server's IP address or Domain name in case primary server does not respond.
Prefer Primary SIP Server	Default is No. If set to yes, it will register to Primary Server if registration with Failover server expires
Outbound Proxy	IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border Controller. Used by DP715 for firewall or NAT penetration in different network environments. If symmetric NAT is detected, STUN will not work and ONLY outbound proxy can correct the problem.
SIP transport	User can select UDP or TCP or TLS. Default is UDP.
NAT Traversal (STUN)	This parameter defines whether or not the DP715 NAT traversal mechanism is activated.If activated (by choosing "Yes") and a STUN server is also specified, then the DP715 performs according to the STUN client specification. Using this mode, the embedded STUN client will detect if and what type of firewall/NAT. If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the DP715 will use its mapped public IP address and port in all of its SIP and SDP messages.If the NAT Traversal field is set to "Yes" with no specified STUN server, the DP715 will periodically (every 20 seconds or so) send a blank UDP packet (with no payload data) to the SIP server to keep the "hole" on the NAT open.
Advance Configuration
DNS Mode	One from the 3 modes are available for "DNS Mode" configuration:-A Record (for resolving IP Address of target according to domain name)-SRV (DNS SRV resource records indicates how to find services for various protocols)-NAPTR/SRV (Naming Authority Pointer according to RFC 2915)One mode can be chosen for the client to look up server.The default value is "A Record"
Tel URI	The default setting is "Disabled". If the phone has an assigned PSTN Number, this field should be set to "User=Phone" then a "User=Phone" parameter will be attached to the "From header" in the SIPrequest to indicate the E.164 number. If server supports TEL URI format, then this option needs to be selected.

Use Random Port	Default is No. This parameter forces the random generation of both the local SIP and RTP ports when set to Yes. This is usually necessary when multiple DP715 are behind the same NAT.
Refer-To Use Target Contact	Default is No. If set to YES, then for Attended Transfer, the "Refer-To" header uses the transferred target's Contact header information.
Transfer on Conference Hang up	Default is No. In which case if the conference originator hangs up the conference will be terminated. When option YES is chosen, originator will transfer other parties to each other so that B and C can choose to either continue the conversation or hang up.
Disable Bellcore Style 3-Way Conference	Default is No. you can make a Conference by pressing 'Flash' key. If set to Yes, you need to dial *23 + second callee number.
Remove OBP from Route Header	Default is No. When option YES is chosen, the Out Bound Proxy will be removed from Route header.
Support SIP Instance ID	Default is Yes. If set to Yes, the contact header in REGISTER request will contain SIP Instance ID as defined in IETF SIP Outbound draft.
Validate incoming SIP	Default is No. If set to yes all incoming SIP messages will be strictly validated according to
message	RFC rules. If message will not pass validation process, call will be rejected.
Check SIP User ID for incoming INVITE	Default is No. Check the incoming SIP User ID in Request URI. If they don't match, the call will be rejected. If this option is enabled, the device will not be able to make direct IP calls.
Authenticate incoming INVITE	After enable, unit will challenge any incoming INVITE with the SIP account password.
Allow Incoming SIP Messages from SIP Proxy Only	Default is No. Check the incoming SIP messages. If they don't come from the SIP proxy, they will be rejected. If this option is enabled, the device will not be able to make direct IP calls.
SIP T1 Timeout	T1 is an estimate of the round-trip time between the client and server transactions. If the network latency is high, select larger value for more reliable usage. Default is 0.5 Sec.
SIP T2 Interval	Maximum retransmission interval for non-INVITE requests and INVITE responses. Default is 4 Sec.
DTMF Payload Type	Sets the payload type for DTMF using RFC2833. Default is 101.

Delayed Call Forward Wait Time	Default value is 20 seconds. In case this feature activated using * codes (*92 code), the call will be forwarded after this preconfigured amount of time.
No Key Entry Timeout	Default is 4 seconds. Dialing process is completed and outgoing call is initiated if no key entry occurs during this preconfigured interval.
Early Dial	Default is No. Use only if proxy supports 484 response. This parameter controls whether the phone will send an early INVITE each time a key is pressed when a user dials a number. If set to "Yes", an INVITE is sent using the dial-number collected thus far; Otherwise, no INVITE is sent until the "(Re-)Dial" button is pressed or after about 5 seconds have elapsed if the user forgets to press the "Re-Dial" button.The "Yes" option should be used ONLY if there is a SIP proxy configured and the proxy server supports 484 Incomplete Address response. Otherwise, the call will likely be rejected by the proxy (with a 404 Not Found error).This feature does NOT work with and should NOT be enabled for direct IP-to-IP calling.
Dial Plan Prefix	Sets the prefix added to each dialed number.
Use # as Dial Key	Default is Yes. It allows users to configure the "#" key as the "Send" (or "Dial") key. If set

SAVING THE CONFIGURATION CHANGES

Click the "Update" button in the Configuration page to save the changes to the DP715 configuration. The following screen confirms that the changes are saved. Reboot or power cycle the DP715 to make the changes take effect.

REBOOTING THE DP715 BASE STATION FROM REMOTE

Press the "Reboot" button at the bottom of the configuration menu to reboot the DP715 Base Station remotely. The web browser will then display a message window to confirm that reboot is underway. Wait 30 seconds to log in again.

CONFIGURING THE DP715 BASE STATION THROUGH A CENTRAL SERVER

Grandstream DP715 can be automatically configured from a central provisioning system.

When DP715 boots up, it will send TFTP or HTTP/HTTPS requests to download configuration files, "cfg000b82xxxxxx" and "cfg00082xxxxxx.xml", where "000b82xxxxxx" is the LAN MAC address of the DP715. If the download of "cfgxxxxxxxxxxxx.xml" is not successful, the provision program will issue request a generic configuration file "cfg.xml". Configuration file name should be in lower case letters.

The configuration data can be downloaded via TFTP or HTTP/HTTPS from the central server. A service provider or an enterprise with large deployment of DP715 can easily manage the configuration and service provisioning of individual devices remotely from a central server.

Grandstream provides a central provisioning system GAPS (Grandstream Automated Provisioning System) to support automated configuration of Grandstream devices. GAPS uses enhanced (NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each individual Grandstream device for firmware upgrade, remote reboot, etc.

Grandstream provides GAPS service to VoIP service providers. Use GAPS for either simple redirection or with certain special provisioning settings. At boot-up, Grandstream devices by default point to Grandstream provisioning server GAPS, based on the unique MAC address of each device, GAPS provision the devices with redirection settings so that they will be redirected to customer's TFTP or HTTP/HTTPS server for further provisioning.

Grandstream also provides configuration tools (Windows and Linux/Unix version) to facilitate the task of generating device configuration files. The Grandstream configuration tools are free to end users. The configuration tools and configuration templates are available for download from http://www.grandstream.com/support/tools.

SOFTWARE UPGRADE

Software upgrade can be done via either TFTP or HTTP or HTTPS. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page.

FIRMWARE UPGRADE THROUGH TFTP/HTTP/HTTPS

To upgrade via TFTP or HTTP/HTTPS, the "Firmware Upgrade and Provisioning upgrade via" field needs to be set to TFTP HTTP or HTTPS, respectively. "Firmware Server Path" needs to be set to a valid URL of a TFTP or HTTP server, server name can be in either FQDN or IP address format. Here are examples of some valid URL.

e.g. firmware.mycompany.com:6688/Grandstream/1.0.0.23

e.g.firmware.grandstream.com

NOTES:

- Firmware upgrade server in IP address format can be configured via IVR. Please refer to the CONFIGURATION GUIDE section for instructions. If the server is in FQDN format, it must be set via the web configuration interface.

- Grandstream recommends end-user use the Grandstream HTTP server. Its address can be found at http://www.grandstream.com/support/firmware. Currently the HTTP firmware server FQDN is "firmware.grandstream.com". For large companies, we recommend to maintain their own TFTP/HTTP/HTTPS server for upgrade and provisioning procedures.

- Once a "Firmware Server Path" is set, user needs to update the settings and reboot the device. If the configured firmware server is found and a new code image is available, the DP715 will attempt to retrieve the new image files by downloading them into the DP715's SRAM. During this stage, the DP715's LEDs will blink until the checking/downloading process is completed. Upon verification of checksum, the new code image will then be saved into the Flash. If TFTP/HTTP/HTTPS fails for any reason (e.g. TFTP/HTTP/HTTPS server is not responding, there are no code image files available for upgrade, or checksum test fails, etc), the DP715 will stop the TFTP/HTTP/HTTPS process and simply boot using the existing code image in the flash.

- Firmware upgrade may take as long as 15 to 30 minutes over Internet, or just 5 minutes if it is performed on a LAN. It is recommended to conduct firmware upgrade in a controlled LAN environment if possible. For users who do not have a local firmware upgrade server, Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware upgrade.

- Grandstream's latest firmware is available at http://www.grandstream.com/support/firmware. Oversea users are strongly recommended to download the binary files and upgrade firmware locally in a controlled LAN environment.

Note: Alternatively, the user can upload the firmware single file from his/her computer using a local directory. For more instructions see below. Also the user can download a free TFTP or HTTP server and conduct local firmware upgrade. A free windows version TFTP server is available for download from http://support.solarwinds.net/updates/New-customerFree.cfm. Our latest official release can be downloaded from http://www.grandstream.com/support/firmware.

INSTRUCTIONS FOR UPLOAD FROM LOCAL DIRECTORY

1. Download the firmware file from Grandstream web site
2. Unzip it and copy the file in to a folder in your PC
3. From the DP715 web interface (Advanced Settings page) you can browse your hard drive and select the folder where you previously saved the file.
4. Click "Upload Firmware" and wait few minutes until the new program is loaded.

Note: Always check the status page to see that the program version has changed.

INSTRUCTIONS FOR LOCAL FIRMWARE UPGRADE USING TFTP SERVER

1. Unzip the file and put all of them under the root directory of the TFTP server.
2. Put the PC running the TFTP server and the DP715 device in the same LAN segment.
3. Please go to File -> Configure -> Security to change the TFTP server's default setting from "Receive Only" to "Transmit Only" for the firmware upgrade.
4. Start the TFTP server, in the phone's web configuration page
5. Configure the Firmware Server Path with the IP address of the PC
6. Update the change and reboot the unit

End users can also choose to download the free HTTP server from http://httpd.apache.org/ or use Microsoft IIS web server.

Grandstream SIP Device can be configured via Web Interface as well as via Configuration File through TFTP or HTTP/HTTPS. "Config Server Path" is the TFTP or HTTP/HTTPS server path for configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The "Config Server Path" can be same or different from the "Firmware Server Path".

A configuration parameter is associated with each particular field in the web configuration page. A parameter consists of a Capital letter P and 1 to 3 (Could be extended to 4 in the future) digit numeric numbers. i.e., P2 is associated with "Admin Password" in the ADVANCED SETTINGS page. For a detailed parameter list, please refer to the corresponding firmware release configuration template.

When a Grandstream device boots up or reboots, it will issue a request for a configuration file "cfgxxxxxxxxxxxx", where "xxxxxxxxxxxx" is the MAC address of the device, i.e., "cfg000b820102ab". In addition, device will also requests a XML configuration file "cfgxxxxxxxxxxxx.xml". If the download of "cfgxxxxxxxxxxxx.xml" is not successful, the provision program will issue a request for a generic configuration file "cfg.xml". Configuration file name should be in lower case letters.

For more details on XML provisioning, please refer to: http://www.grandstream.com/general/gs_provisioning_guide_public.pdf

FIRMWARE AND CONFIGURATION FILE PREFIX AND POSTFIX

Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix and Postfix. This makes it the possible to store ALL of the firmware with different version in one single directory.

Similarly, Config File Prefix and Postfix allows device to download the configuration file with the matching Prefix and Postfix. Thus multiple configuration files for the same device can be stored in one directory.

In addition, when the field "Check New Firmware only when F/W pre/suffix changes" is set to "Yes", the device will only issue firmware upgrade request if there are changes in the firmware Prefix or Postfix.

MANAGING FIRMWARE AND CONFIGURATION FILE DOWNLOAD

When “Automatic Upgrade” is set “Yes, every” the auto check will be done in the minute specified in this field. If set to “daily at hour (0-23)”, Service Provider can use P193 (Auto Check Interval) to have the devices do a daily check at the hour set in this field with either Firmware Server or Config Server.

BASE STATION

There are Three (3) methods for resetting the DECT base station:

1. Reset Button

Reset default factory settings following these four (4) steps:

1. Unplug the Ethernet cable.
2. Locate a needle-sized hole on the back panel of the gateway unit next to the power connection.
3. Insert a pin in this hole, and press for about 7 seconds.
4. Take out the pin. All unit settings are restored to factory settings.

2. IVR Command

Reset default factory settings using the IVR Prompt (Table 5):

1. Dial “***” for voice prompt.
2. Enter "99" and wait for "reset" voice prompt.
3. Enter the encoded MAC address (Look below on how to encode MAC address).
4. Wait 15 seconds and device will automatically reboot and restore factory settings.

Encode the MAC Address

1. Locate the MAC address of the device. It is the 12 digit HEX number on the bottom of the unit.
2. Key in the MAC address. Use the following mapping:

0-9: 0-9

A: 22 (press the "2" key twice, "A" will show on the LCD)

B: 222

C: 2222

D: 33 (press the "3" key twice, "D" will show on the LCD)

E: 333

F: 3333

For example: if the MAC address is 000b8200e395, it should be keyed in as "000228200333395".

3. Reset from web interface (Reset Type)

1. From the Advanced Settings Page user can select three types:

• Full Reset: This will make a full reset
- ISP Data: This will reset only the basic settings, like IP mode, PPPoE and Web port

- VOIP Data: This will reset only the data related with a service provider like SIP server, sip user ID, provisioning and others.

Note:

1. Factory Reset will be disabled if the "Lock keypad update" is set to "Yes".

2. If the DP715 was previously locked by your local service provider, pressing the RESET button will only restart the unit. The device will not return to factory default settings.
