Tel Profile Parameter Global Parameter
Note: The corresponding global parameter is DTMFVolume.
Input Gain
input-gain
[TelProfile_InputGain]
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.
Voice Volume
voice-volume
[TelProfile_VoiceVolume]
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
Enable AGC
enable-agc
[TelProfile_EnableAGC]
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.
 [0] Disable (default)
 [1] Enable
Note:
 For a description of AGC, see 'Automatic Gain Control
(AGC)' on page 221.
 The corresponding global parameter is EnableAGC.
Analog
Enable Polarity Reversal
polarity-rvrsl
[TelProfile_EnableReversePolarity]
Enables the Polarity Reversal feature for call release.
 [0] Disable (default)
 [1] Enable = Enables polarity reversal:

FXS Interfaces: The device changes the line polarity on
call answer and then changes it back on call release.

FXO Interfaces: The device sends a SIP 200 OK
response when polarity reversal signal is detected
(applicable only to one-
stage dialing) and releases a call
when a second polarity reversal signal is detected.
Note:
 The parameter is applicable to FXS and FXO interfaces.
 The corresponding global parameter is
EnableReversalPolarity.
Enable Current Disconnect
current-disconnect
[TelProfile_EnableCurrentDisconnect]
Enables call release upon detection of a Current Disconnect
signal.
 [0] Disable (default)
 [1] Enable = Enables the current disconnect service.

FXO Interfaces: The device releases a call when a
current disconnect signal is detected on its port.

FXS Interfaces: The device generates a 'Current
Disconnect Pulse' after the call is released from the IP
side.
Note:
 The parameter is applicable to FXS and FXO interfaces.
 The current disconnect duration is configured by the
CurrentDisconnectDuration parameter.
 The current disconnect threshold (FXO only) is configured
