FIGURE 37. VLink Client Data, Audio, SIP Data, RTP Audio Base fields

Server IP Ports for VLink Client Data Field

The Server IP Ports for VLink Client Data field is used to control the TCP/IP port that all client side control panels and device interfaces use to transport data to the virtual matrix. If the virtual matrix is behind a firewall and external access is required, a port forwarding entry must be added to route all traffic on this port to the internal virtual matrix IP Address.

The default for this field is port 1000.

Server IP Ports for VLink Client Audio Field

The Server IP Ports for VLink Client Audio field is used to control the UDP port that all client side control panels and device interfaces use to transport audio to the virtual matrix. The system has no restriction other than reserved ports. If the virtual matrix is behind a firewall and external access is required, a port forwarding entry must be added to route all traffic on this port to the internal virtual matrix IP Address.

The default for this field is port 1000.

Server IP Ports for SIP Data Field

The Server IP Ports for SIP Data field is used to define the IP Port for the integrated SIP server. In general, this value never changes because it is an industry standard port number; however, the value must be changed if multiple VLink virtual matrix instances are to be run on the same physical computer.

The default for this field is 5060.

Server IP Ports for RTP Audio Base Field

The Server IP Ports for RTP Audio Base field is used to establish the IP port number. When set to zero (0), all SIP RTP session establish the IP Port randomly in the range of 10000–42767. In many situations this is adequate, however, if the audio must travel through a firewall, it is not practical or safe to open such a large range of addresses. By specifying an RTP audio base port, the system assigns IP ports sequentially upward from the assigned base port. Once an IP port is assigned to a SIP client, it never changes unless the base port changes.

Server SIP Domain Name Field

The Server SIP Domain Name field is used to define the optional SIP domain for the integrated SIP server. If the SIP domain is specified, it can be used as the SIP proxy name and the registrar name when configuring SIP clients. Whether or not the SIP domain is specified, the virtual matrix IP Address can always be used as the proxy name and the registrar name.

Secondary (Failover) Server Network Settings Group Box

The Secondary (Failover) Server Network Settings group box is used to configure the IP Address or SIP information for the secondary server used to run the application if the primary server has a failure.

Server IP Address Field

Server IP Ports for VLink Client Data Field

The Server IP Ports for VLink Client Data field is used to control the TCP/IP port that all client side control panels and device interfaces use to transport data to the virtual matrix. If the Virtual Matrix is behind a firewall and external access is required, a port forwarding entry must be added to route all traffic on this port to the internal virtual matrix IP Address.

The default for this field is port 1000.

Server IP Ports for VLink Client Audio Field

The Server IP Ports for VLink Client Audio field is used to control the UDP port that all client side control panels and device interfaces use to transport audio to the virtual matrix. The system has no restriction other than reserved ports.

NOTE: Higher audio sampling rates have more significant requirements both in computational speed and network bandwidth, so careful consideration must be made when choosing this setting with respect to client hardware and the client network connection.

Available selections for this field are:

Ultra Wideband (32KHz) Default

Wideband (16KHz)

Narrowband (8KHz)

TABLE 2. Bandwidth Utilization

Audio Sample Rate	Data Rate (Kbps) [ATS a =20ms]			Data Rate (Kbps) [ATS a =40ms]			Data Rate (Kbps) [ATS a =60ms]	Data Rate (Kbps) [ATS a =80ms]	Data Rate (Kbps) [ATS a =100ms]
8KHz	32	23.6	20.8	19.4	18.56
16KHz	44.8	36.4	33.6	32.2	31.36
32KHz 46.	8	38.4	35.6	34.2	33.36

a. ATS (Audio Time Slice) per packet controls how many 20ms audio frames are transmitted within a single UDP packet. As each UDP packet requires a fixed amount of overhead, the more frames sent at the same time, the less the UDP overhead is used, which conserves network bandwidth. Conversely, the more audio frames sent per transmission, the greater the system latency and the potential audible consequence of a lost packet. The default is 20ms.

The Audio Encode Quality field and slider are used to set the compression rate for the audio. The higher the compression is, the lower the quality of the input speech signal. Unlike some other speech codecs, it is possible to control the trade-off made between quality and bit rate.

Available options for this field are: -8, -7, -6, -5, -4, -3, -2, -1, Standard, +1, and +2.

Audio Encode Complexity Field and Slider

The Audio Encode Complexity field and slider is used to elevate the audio complexity level to achieve superior results when encoding non-speech sounds, like DTMF tone.

Available options for this field are: 1, Standard, +1, +2, +3, +4, +5, +6, +7, and +8.

Variable Bit Rate Check Box

The Variable Bit Rate check box indicates the system's codec is allowed to dynamically change the bit rate at which audio is being encoded. Sounds, like vowels, require a higher bit rate to achieve good quality as compared to "s" and "f" sounds, this setting achieves the best sound quality within the given confines. The system can be set for variable rate or fixed rate. While this setting improves the quality of speech, it conversely degrades the quality of music and should therefore be disabled when using a program feed.

Audio Transmission Group Box

Audio Capture Buffer Size Field and Slider

The Audio Capture Buffer Size field and slider are used to control the size of the audio capture buffer used by the VLink control panel and VLink device interface when using the Microsoft WDM drivers. With some slower computers and/or handhelds, the audio capture buffer size may need to be increased in order to prevent audio overrun issues.

NOTE: Increasing this value also increases the audio latency.

Available options for this field are: 20ms, 40ms, 60ms, 80ms, 100ms, 120ms, 140ms, 160ms, 180ms, and 200ms. The default value for this field is 20ms.

Audio Time Slice Per Packet Field and Slider

The Audio Time Slice Per Packet field and slider is used to control how may 20ms audio frames are transmitted within a single UDP packet. As each UDP packet represents a fixed amount of overhead, the more frames sent at the same time the less UDP overhead which conserves network bandwidth. Conversely, the more frames sent per transmission, the greater the system latency and audible consequence of lost packets, e.g. 20ms of lost frames is hardly audible, where 40ms is.

Available options for this field are: 20ms, 40ms, 60ms, 80ms, and 100ms. The default for this field is 20ms.

Jitter Buffer Size Field and Slider

The Jitter Buffer Size field and slider is used to specify the depth of the jitter buffer in milliseconds. In network-based communications, the delivery time of audio packets across the network may not be uniform. This characteristic is known as jitter. As such, audio received from a network connection must be buffered to compensate for this such that a continuous time-relative stream of audio can be delivered to the user of the audio. Different network topologies have different jitter characteristics, for example, a public Internet connection, will have significantly more jitter than an internal local network. The effect of a jitter buffer that is set too small, results in audio gaps. The value is specified in milliseconds.

Available options for this field are: 20ms, 40ms, 60ms, 80ms, 100ms, 120ms, 140ms, 160ms, 180ms, and 200ms. The default for this field is 20ms.

Silence Suppression Time Field and Slider

The Silence Suppression Time field and slider are used to cease all transmission of audio data when no voice activity is detected from a control panel or device interface after the specified time lapse. This eliminates most background noise during multi-party conferences; however, it may be initially disconcerting to some individuals as the comfort noise typically associated with analog systems is suppressed. Additionally, this feature minimizes the overall required network bandwidth. The value is specified in milliseconds in the range of 100–1000ms, or can be turned off completely.

Available options for this field are: Off, 100ms, 200ms, 300ms, 400ms, 500ms, 600ms, 700ms, 800ms, 900ms, and 1000ms. The default for this field is 1000ms.

Packet Resequencer Depth Field and Slider

The Packet Resequencer Depth field and slider is used to specify the number of packets that are stored when waiting for an out of sequence audio packet. In some network topologies, UDP packets are sent in sequential order are received non-sequentially. As such, these packets must be re-sequenced before use. After the maximum re-sequencer depth has been reached, the packet being waited for is declared to be lost and the re-sequencing is restarted at the next earliest received packet.

Available options for this field are: 1 packet, 2, packets, 3 packets, 4 packets, 5 packets, 6 packets, 7 packets, 8 packets, 9 packets, and 10 packets.

The default for this field is 6 packets.

Audio Levels Group Box

Automatic Gain Control Check Box

The Automatic Gain Control check box enables or disables AGC (Automatic Gain Control) on the audio path from client to the server. AGC automatically increases or decreases the audio level that the client presents a uniform audio level to the virtual matrix. AGC is primarily appropriate for use with a control panel when used with a headset microphone. In some situations, where there is a high amount of background noise or some return audio leakage, the AGC may incorrectly amplify the noise to normal audio levels.

Automatic Gain Control Level Field and Slider

The Automatic Gain Control Level field and slider is used to increase or decrease the sensitivity of the AGC. Increasing or decreasing the sensitivity of the AGC, changes the behavior of the AGC that it adapts faster or slower to audio levels not considered to be at uniform level. Decreasing the sensitivity may be useful in cases where there is a high amount of background noise or some return audio leakage.

Available options for this field are: -8, -7, -6, -5, -4, -3, -2, -1, Standard, +1, +2, +3, +4, +5, +6, +7, +8, +9, +10, +11, +12, +13, +14, +15, +16, +17, +18, +19, +20, +21, +22, and +23.

The default for this field is Standard.

Audio Input Level Gain (Pre-Mix) Field and Slider

The Audio Input Level Gain (Pre-Mix) field and slider is used to control the audio input level sent from the client to the virtual matrix. This setting is typically used only when the client's audio input device does not provide a sufficiently audible level (as heard by all other clients) and does not have a local gain control to compensate. The value can be adjusted a maximum of ±18dB in 6dB increments.

Available options for this field are: -18dB, -12dB, -6dB, 0dB, +6dB, +12dB, and +18dB. The default for this field is 0dB.

Audio Output Level Gain (Post-Mix) Field and Slider

The Audio Output Level Gain (Post-Mix) field and slider is used to control the audio output level sent to the client from the virtual matrix. This setting is typically used only when the client's audio output device does not provide a sufficiently audible level and does not have a local gain control to compensate. The value can be adjusted a maximum ±18dB in 6dB increments.

Available options for this field are: -18dB, -12dB, -6dB, 0dB, +6dB, +12dB, and +18dB. The default for this field is 0dB.

Speakerphone Speaker Dim Reduction Field and Slider

The Speakerphone Speaker Dim Reduction field and slider are used to adjust the audio level of the speaker phone by lowering the Dim level.

Available options for this field are: None, -6dB, -12dB, -18dB, -24dB, -30dB, -36dB, and Mute. The default for this field is -12dB.

Audio Processing Group Box

Echo Cancellation Check Box

The Echo Cancellation check box is used to enable or disable the client's echo cancellation. Echo cancellation is useful if there is any return audio leakage from the client's speaker back to their microphone, as this may result in an audible echo heard by any other client that is talking and listening to the client with the return audio leakage.

Echo Cancellation Tail Length Field and Slider

The Echo Cancellation Tail Length field and slider is used to control the duration the echo canceller waits to received the echo before it begins the cancellation process. The recommended tail length is approximately a third of the room reverberation time. For example, in a small room, reverberation time is approximately 300ms. A tail length of 100ms is recommended.

Available options for this field are: 50ms, 100ms, 150ms, 200ms, 250ms, and 300ms. The default for this field is 100ms.

• If configured for On Forced Disconnect, the call initiated by the SIP client can only be disconnected by the control panel using the disable client login feature.
• If configured for On Talk Selector Deactivation, the call initiated by the SIP client disconnects when all control panels deactivate the talk selectors associated with the SIP client.

Outbound Session Activation Drop Down Menu

The Outbound Session Activation drop down menu is used to select how the virtual matrix handles the activation of a call initiated to the SIP client.

Available options for this field are:

• If configured for Disabled, the virtual matrix cannot initiate any call to the SIP client.
• If configured for On Registration, the virtual matrix initiates a call to the SIP client as soon as the SIP client makes its presence known through a process know as Registration.
• If configured for On Talk Selector Activation, the virtual matrix initiates a call to the SIP client when any control panel activates the talk selector associated with the SIP client.

Outbound Session Deactivation Drop Down Menu

The Outbound Session Deactivation drop down menu is used to select how the virtual matrix handles the deactivation of a call initiated to the SIP client.

Available options for this field are:

• If configured for Disabled, the call initiated to the SIP client can never be disconnected by the virtual matrix.
• If configured for On Forced Disconnect, the call initiated to the SIP client can only be disconnected by a control panel using the Disable Client Login feature.
• If configured for On Talk Selector Deactivation, the call initiated to the SIP client disconnects when all control panels deactivate the talk selectors associated with the DIP client.

Automatic Dial Sequence Field

The Automatic Dial Sequence field is used to specify a dial sequence to be dialed as soon as a call is established with a SIP client.

To insert a delay in the dial sequence, do the following:

In the Automatic Dial Sequence field, enter P to insert a five (5) second delay. OR
In the Automatic Dial Sequence field, enter p to insert a one (1) second delay.

Send SDP With Invite Request Check Box

The Send SDP With Invite Request check box is used to change the default behavior of call initiated by the virtual matrix to allow compatibility with devices that do not conform to proper SIP implementation. Normally when the virtual matrix initiates a call to the SIP client, it does so without sending a SDP (Session Description Protocol) so that it can subsequently control the codec selection.

Use SDP for RTP Destination Check Box

The Use SDP for RTP Destination check box is used to change the default behavior of the virtual matrix to allow strict conformance with the RTP (Real-Time Protocol) specification. Normally, the virtual matrix ignores the RTP IP Address specified in the SDP and uses the actual received RTP IP Address as the SIP specification as written does not account for SIP clients behind NAT firewalls.

TROUBLESHOOTING

Following are answers to the most commonly experienced issues of new users.

Question Answer

When attempting to login to the Virtual Matrix I get a “Cannot connect to Virtual Matrix” message?

The Device Interface is unable to establish a TCP/IP data connection with the Virtual Matrix. Check the Device Interface Configuration to ensure Device Interface IP Address is valid and represents a valid and active network connection. Ensure that the Virtual Matrix IP Address is entered exactly as provided with the designated port number. Check to ensure a corporate firewall is not intentionally blocking the designated TCP/IP data port.

When attempting to login to the Virtual Matrix I get a “Unable to establish return audio path” message?

The Device Interface is unable to establish a UDP audio connection with the Virtual Matrix. Check to ensure a corporate firewall is not intentionally blocking the designated UDP audio port which is typically the same as the TCP/IP data port.

When attempting to log in to the Virtual Matrix I get a Provided username and/or password is invalid! message?

The Device Interface is unable to validate the username and password. Check to ensure the name is typed exactly as provided as the username and password are both case sensitive. Check to ensure the correct TCP/IP data port is specified to ensure you are logging in to the correct system.

Overview

SIP (Session Initiation Protocol) is a widely adopted signaling protocol for Internet conferencing, telephony, presence, events notification and instant messaging.

The VLink Virtual Matrix includes an integrated SIP server which allows connection of SIP enabled VoIP (Voice over Internet Protocol) peripherals directly into the virtual matrix from any network connection without the need for a PC. You can seamlessly connect IP phones/phone systems, ATAs (Analog Telephone Adapters), or IP gateways into a network and using the VLink system administration application, map your SIP peripherals to point-to-points, group calls, and/or party lines in any complexity.

Typically, SIP devices are used with Telephone IP PBX (Private Branch Exchange) systems to implement a traditional telephone system whereby one (1) user dials the number of another user and waits for the recipient to answer. VLink, however, is an always on non-blocking intercom system and as such, the SIP implementation has been tailored to best compliment this functionality. As such, each configured SIP client becomes an extension of a VLink port by connecting the SIP device to a dedicated virtual SIP client associated with a VLink port.

There are many ways SIP devices can be utilized with VLink. Below are a number of common applications:

Interoperating ProComm and IP Phone Systems:

ProComm Administrators can seamlessly bridge intercom with widely deployed IP Phone Systems which are prevalent in the governmental and defense markets.

Interfacing Phone Lines:

Analog and digital phone lines can be bridged into VLink from any network connecting using SIP-ready VoIP gateways.

Party Line Systems:

Users with simple intercommunication requirements, such as only needing to monitor or talk on one (1) or two (2) channels have a wide array of user interface options that do not require a PC. Options include WiFi enabled IP phones, iPhones (running softphone clients), and desktop speaker phones.

Hoot n' Holler: VLink is widely deployed as a next generation Hoot n' Holler

system replacing private circuit leased lines from the phone companies which are expensive and can have a low quality of service. In this application most users have the simple requirement of monitoring and talking on a single party line and use an analog telephone attached to an ATA or IP phone, requiring no client-side PCs.

Configuring VLink for SIP Devices

A SIP Device is added or edited in the VLink System Administration application under Client Configuration, in the same fashion as a VLink control panel or VLink device interface. The SIP device connection that is established can be configured in different ways to suit the application and/or the device.

For SIP devices with a DTMF (Dual Tone Multi-Frequency) or touch-tone keypad, VLink talk/listen selectors can be assigned to activate with the DTMF access codes.

Configuring SIP Devices for VLink

Softphones

To configure a SIP phone, do the following:

1. Configure the SIP phone with the following:

• IP Address or the Domain Name of the SIP Server
- Account Name
- Password

1. In the SIP Default Port number field, enter 5060.

NOTE: Unless changed in the VLink System Administration, the standard SIP default port number is 5060.

1. In the Display Name field, enter the display name desired.
2. In the User Name field, enter the username.
3. In the Password field, enter the password.

IMPORTANT: The Display Name, Username, and Password must match the settings configured under Client Configuration for any given softphone.

Hardphones and ATAs

SIP hardphones and ATAs are configured via a web interface. You need to begin by determining the device IP Address typically by using Internet Explorer to access your router's web interface and view the list of attached devices.

Once you determine your devices IP Address input it into a web browser to access the device's configuration page. Use your VLink Server IP Address as the Domain, Proxy, and the Registrar address. Unless changed in the VLink System Administration the standard SIP default port number is 5060. Set the Display Name, User Name, and Password to match the settings programmed in the 'Client Configuration' section of the VLink System Administration for any given hardphone or ATA.

Network Bandwidth Requirements Guide

The network bandwidth requirements must be carefully analyzed to ensure proper bandwidth is available at any point where multiple clients will share the same physical connection point. The most obvious connection point where this is critical is at the server where bandwidth requirements are the sum of the requirements of every possible client. The least obvious connection point where this is also important occurs when multiple remote in one (1 physical location need to access the server in another physical location as the bandwidth requirements for the connection between these two (2) points is the sum of the requirements for all remote clients.

To determine the bandwidth requirements, it is necessary to determine the network bandwidth utilization per client connection, which is indicated below for the various audio sample rates that can be configured.

TABLE 3. Network Bandwidth Utilization

Audio Sample Rate	Data Rate (Kbps) (ATS=20msa)	Data Rate (Kbps) (ATS=20msa)	Data Rate (Kbps) (ATS=20msa)	Data Rate (Kbps) (ATS=20msa)	Data Rate (Kbps) (ATS=20msa)
8KHz 32 23.6 20.8	19.4 18.56
16KHz 44.8 36.4 33	3.6 32.2 31.36
32KHz 46.8 38.4 35	5.6 34.2 33.36

a. ATS=Audio Time Slice per packet which controls how many 20ms audio frames are transmitted within a single UDP packet. As each UDP packet requires a fixed amount of overhead, the more frames went at the same time, the less the UDP overhead which conserves network bandwidth. Conversely, the more audio frames sent per transmission, the greater the system latency and the potential audible consequence of a lost packet. The default is 20ms.

To determine server bandwidth requirements, do the following:

1. Determine maximum potential bandwidth utilization by multiplying the number of clients (users and devices interfaced) by the Data Rate associated with appropriate Audio Sample Rate for the configured Audio Time Slice per packet.

The product is the bandwidth required if every client were to receive audio simultaneously (maximum download bandwidth requirement) and also the bandwidth required if every client were to send audio simultaneously (maximum upload bandwidth requirement).

In a typical system, the maximum download bandwidth requirement must be allocated for, as several system functions can require simultaneous audio transmission to all clients. The maximum upload bandwidth requirement however can realistically never be achieved, as it is not feasible that all audio sources in a system would be active simultaneously since the result would be inaudible. As such, the upload bandwidth to be allocated must be made based on the estimation of the number of simultaneous active audio sources noting that inactive audio has no bandwidth requirements.

Audio Sampling Rate. The number of times per second an analog audio wave form is digitally sample, i.e. takes a “digital snapshot” to create a digital representation. The more samples taken, the higher the fidelity.

Automatic Gain Control (AGC). An adaptive system where the average signal level is used to adjust the gain to an appropriate level for a range of input signal levels. AGC reduces the volume if the signal is strong and raises it when it is weaker.

Client. A VLink specific term to refer collectively to either a Control Panel or Device Interface.

Control Panel. VLink's client-side GUI (Graphical User Interface) enabling users to conduct communications using color coded selectors which represent audio/voice channels.

Device Interface. VLink's client-side software application that bridges VLink with multiple external communications systems.

IFB. An abbreviation for Interrupt Foldback or Interrupt Feedback. It is sometimes referred to as PI (Program Interrupt). In radio and television broadcasting, IFB serves as a voice cuing mechanism for the on air talent. The talent listens to a program audio signal which can be interrupted by the voice of a production person, such as a director or producer, for the purpose of giving instructions to the talent regarding the show in progress. This is seen by a television viewer as the earpiece that a news announcer wears.

ISO. An abbreviation for Isolate. ISO is a high level intercom function by which a temporary and private communications link is established between an operator who is located at an intercom control panel and another operator. The function is valuable wherever a short term private exchange is required between two (2) operators who are normally sharing the conversation required to accomplish a group activity. When any two (2) people need to talk together without interfering with or being heard by anyone else, ISO is the function required. The most common application is that of a video control operator and television camera operator.

System Administration. VLink's client-side system administration application which allows for dynamic configuration from any workstation or the server hosting the Virtual Matrix.

SIP. An abbreviation for session initiation protocol. SIP is a widely adopted signalling protocol for Internet conferencing, telephony, presence, events notification, and instant messaging. By supporting SIP, VLink can readily interface with many commonly used IP phones, IP phone systems, and other SIP-compliant devices.

Operation

Basic Functionality And Features

FIGURE 58. VLink Mobile Device Assignments

Talk/Listen Selectors

The main display provides a series of buttons referred to as Talk and Listen selectors. An available Talk selector is red and an available Listen selector is green. Some selector provide for dual Talk/Listen selector operation. The Talk and Listen selectors are optionally shown with a Selector Legend indicated as 'L' for Listen and 'T' for Talk for operators with color recognition disabilities. If a selector is grayed out, this indicates that the source or destination is not connected to the system and as such not available for selecting a talk or listen. To activate a Listen to a particular source click a dim green selector. When active the selector will be bright green. To deactivate a listen to a particular source click the bright green selector. To activate a Talk to a particular destination click a dim red selector. When active the selector will be bright red. To deactivate a talk to a particular source click the bright red selector. To use a selector in momentary mode click and hold the selector; it will deactivate when you release.

Selectors display channel state using the following patterns:

• Voice activity: color oscillation of selector name
- Incoming call: fast flash of talk selector (NOTE: click on the selector to establish a return voice path)
• Device active tally (e.g. telephone off-hook): slow flash of talk selector
• In-use tally: slow double flash of talk selector

A selector can refer to either an individual source or destination or to a Group Call or Party Line. A Group Call is a single selector that activates a Talk and Listen to multiple destinations. A Party Line is a dynamic conference whereby activation of the associated selector automatically makes you a participant of the selected conference. When talking to a Party Line you talk to everyone who is listening to that Party Line. When listening to a Party Line, you listen to everyone who is talking to that Party Line.

VLink Control Panels support virtually an unlimited number of channel selectors. If you have more selectors programmed for your Control Panel than fit on one (1) screen, you must scroll through additional selector screens. If another user calls you, the screen with that user's selector appears so you can easily click on the flashing tally to establish a return voice path.
