Configuring Tel Profile

Defines an index number for the new table row.

Note: Each row must be configured with a unique index.

Defines a descriptive name, which is used when associating the row in other tables.

The valid value is a string of up to 40 characters.

Note:

Defines the priority of the Tel Profile, where 1 is the lowest priority and 20 the highest priority.

Note:

Defines the SIP signaling method for establishing and transmitting a fax session when the device detects a fax.

Note:

Enables the Digit Delivery feature, which sends DTMF digits of the called number to the phone line (device's analog port or digital B-channel) after the call is answered (i.e., line is off-hooked for FXS or seized for FXO) for IP-to-Tel calls.

Digital interfaces: If the called number in IP-to-Tel call includes the characters 'w' or 'p', the device places a call with the first part of the called number (before 'w' or 'p') and plays DTMF digits after the call is answered. If the character 'w' is used, the device waits for detection of a dial tone before it starts playing DTMF digits. For example, if the called number is '1007766p100', the device places a call with 1007766 as the destination number, then after the call is answered it waits 1.5 seconds ('p') and plays the rest of the number (100) as DTMF digits. Additional examples: 1664wpp102, 66644ppp503, and 7774w100pp200.

Note:

Defines the Dial Plan index to use in the external Dial Plan file.

Note: The corresponding global parameter is [DialPlanIndex].

Enables PSTN CAS channels/endpoints to receive incoming IP calls even if the B-channels are in off-hook state.

Note:

Defines call priority handling.

Note:

Enables the device to disconnect the call upon detection of a busy or reorder (fast busy) tone.

Note:

Defines the duration (in seconds) that the device plays a busy or reorder tone before releasing the line.

Analog interfaces: Typically, after playing the busy or reorder tone for this duration, the device starts playing an offhook warning tone.

The valid range is 0 to 254. The default is 0 seconds for analog interfaces and 10 seconds for digital interfaces. Note that the Web interface denotes the default value as "255".

Note:

Enables and disables voice mail services.

The parameter is useful if you want to disable voice mail services per Trunk Group to eliminate the phenomenon of call delay on Trunks that do not implement voice mail when voice mail is configured using the global parameter, VoiceMailInterface.

Enables the device to swap the calling and called numbers received from the Tel side (for Tel-to-IP calls). The SIP INVITE message contains the swapped numbers.

Note: The corresponding global parameter is [SwapTEl2IPCalled&CallingNumbers].

Enables the Cut-Through feature, which allows phones connected to the device’s FXS ports to automatically receive IP calls (if there is no other currently active call) even when in off-hook state (and no call is currently active).

Note:

Defines the DTMF gain control value (in decibels) to the Tel side.

The valid range is -31 to 0 dB. The default is -11 dB.

Note: The corresponding global parameter is [DTMFVolume].

Defines the pulse-code modulation (PCM) input (received) gain control level (in decibels), which is the level of the received signal for Tel-to-IP calls.

The valid range is -32 to 31 dB. The default is 0 dB.

Note: The corresponding global parameter is [InputGain].

Defines the voice gain control (in decibels), which is the level of the transmitted signal for IP-to-Tel calls.

The valid range is -32 to 31 dB. The default is 0 dB.

Note: The corresponding global parameter is [VoiceVolume].

Enables the Automatic Gain Control (AGC) feature. The AGC feature automatically adjusts the level of the received signal to maintain a steady (configurable) volume level.

Note:

Enables the Polarity Reversal feature for call release.

Note:

Enables call release upon detection of a Current Disconnect signal.

Note:

Enables Direct Inward Dialing (DID) using Wink-Start signaling, typically used for signaling between an E-911 switch and the PSAP.

For example: (Wink) KP I(I) xxx-xxxx ST (Off Hook)

Where:

Note: The FXO interface generates such MF digits when the Enable911PSAP parameter is set to 1.

Note:

Enables the support for the E911 DID protocol, according to the Bellcore GR-350-CORE standard. The protocol defines signaling between E911 Tandem Switches and the PSAP, using analog loop-start lines. The device's FXO interface can be used instead of an E911 switch, connected directly to PSAP DID loop-start lines.

Note:

Assigns a Coder Group, which defines audio (voice) coders that can be used for the endpoints associated with the Tel Profile.

To configure Coders Groups, see Configuring Coder Groups.

Defines the DiffServ value for Premium Media class of service (CoS) content.

The valid range is 0 to 63. The default is 46.

Note:

Defines the DiffServ value for Premium Control CoS content (Call Control applications).

The valid range is 0 to 63. The default is 40.

Note:

Enables the Early Media feature, which sends media (e.g., ringing) before the call is established.

Note:

Defines the progress indicator (PI) sent to the IP.

Note: The corresponding global parameter is [ProgressIndicator2IP].

Enables the device's Echo Cancellation feature (i.e., echo from voice calls is removed).

For more information on echo cancellation, see Configuring Echo Cancellation.

Note: The corresponding global parameter is [EnableEchoCanceller].

Enables Non-Linear Processing (NLP) mode for echo cancellation.

Note: The corresponding global parameter is [ECNLPMode].

Defines the minimum delay (in msec) of the device's dynamic Jitter Buffer.

The valid range is 0 to 150. The default delay is 10.

For more information on Jitter Buffer, see Configuring the Dynamic Jitter Buffer.

Note: The corresponding global parameter is [DJBufMinDelay].

Defines the maximum delay (in msec) for the device's Dynamic Jitter Buffer.

The default is 300.

Defines the Dynamic Jitter Buffer frame error/delay optimization factor.

The valid range is 0 to 12. The default factor is 10.

For more information on Jitter Buffer, see Configuring the Dynamic Jitter Buffer.

Note:

Enables the visual display of message waiting indications (MWI).

Note:

Enables sending MWI information to the phone display.

Note:

Defines the maximum duration (timeout) that a message MWI is displayed on endpoint equipment (phones LED, screen notification or voice tone). When the timeout expires, the MWI is removed. However, each time a new MWI is sent to the endpoint, the timeout restarts its countdown again. For example, assume the timeout is configured to 10 seconds and the timeout has 2 seconds left until the current MWI is removed. If the endpoint now receives a new MWI, the timeout starts counting once again from 10 seconds, displaying both MWIs until the timeout expires.

The valid value range is 0 to 2,000,000 seconds, where 0 means unlimited display (default).

Note:

Defines the dialing mode for IP-to-Tel (FXO) calls.

Note:

Enables the FXO Double Answer feature, which rejects (disconnects) incoming (FXO) Tel-to-IP collect calls and signals (informs) this call denial to the PSTN.

Note:

Defines the delay (in msec) before the device generates a SIP INVITE (call) to the IP side upon detection of a RING_START event from the Tel (FXO) side. This occurs instead of waiting for a RING_END event.

The feature is useful for telephony services that employ constant ringing (i.e., when no RING_END is sent). For example, Ringdown circuit is a service that sends a constant ringing current over the line, instead of cadence-based 2 seconds on, 4 seconds off. For example, when a telephone goes off-hook, a phone at the other end instantly rings.

If a RING_END event is received before the timeout expires, the device doesn't initiate a call and ignores the detected ring. The device ignores RING_END events detected after the timeout expires.

The valid value range is 0 to 50 (msec), in steps of 100-msec. For example, a value of 50 represents 5 sec. The default value is 0 (i.e., standard ring operation - the FXO interface sends an INVITE upon receipt of the RING_END event).

Note:

Defines the hook-flash period (in msec) for Tel and IP sides. For the IP side, it defines the hook-flash period reported to the IP. For the analog side, it defines the following:

The valid range is 25 to 3,000. The default is 700.
