Table 5-33: Channel Settings, Voice Settings Parameters
Parameter Description
Voice Volume
[VoiceVolume]
Voice gain control in dB. This parameter sets the level for the transmitted
(IPTel) signal.
You can enter a value from -32 to 31 dB.
The default value is 0 dB.
Input Gain
[InputGain]
PCM input gain control in dB. This parameter sets the level for the received
(TelIP) signal.
You can enter a value from -32 to 31 dB.
The default value is 0 dB.
Note: This parameter is intended for advanced users. Changing it affects other
gateway functionalities.
Silence Suppression
[EnableSilenceCompression]
The parameter SCE is used to maintain
backward compatibility.
Disable [0] = Silence Suppression disabled (default).
Enable [1] = Silence Suppression enabled.
Enable without adaptation [2] = A single silence packet is sent during silence
period (applicable only to G.729).
Silence Suppression is a method conserving bandwidth on VoIP calls by not
sending packets when silence is detected.
Echo Canceler
[EnableEchoCanceller]
The parameter ECE is used to maintain
backward compatibility.
Off [0] = Echo Canceler disabled.
On [1] = Echo Canceler enabled (default).
DTMF Transport Type
[DTMFTransportType]
Determines the method DTMF digits are handled.
Note: If TxDTMFOption or RxDTMFOption parameters are used, then this
parameter (TransportType) is set internally to the right value, and the current
value is ignored.
DTMF Mute [0] = DTMF digits are erased from the voice stream and not relay
to the remote end. DTMF is still sent in out-of-band signaling if you select Yes
for the Enable DTMF over H.245 parameter on the Protocol Definition screen.
DTMF Transparent [2] = DTMF tones are left in the voice stream.
RFC 2833 Relay DTMF [3] = DTMF digits are erased from the voice stream
and relayed to the remote end using RFC 2833 standard (default).
MF Transport Type

[DTMFVolume]
DTMF gain control value in dB.
You can enter a value from -31 to 0 dB.
The default value is -11 dB.
Enable Answer Detector
[EnableAnswerDetector]
N/A.
Answer Detector Activity Delay
[AnswerDetectorActivityDelay]
N/A.
Answer Detector Silence Time
[AnswerDetectorSilenceTime]
N/A.
Answer Detector Redirection
[AnswerDetectorRedirection]
N/A.
Answer Detector Sensitivity
[AnswerDetectorSensitivity]
Determines the Answer Detector sensitivity.
The range is 0 (most sensitive) to 2 (least sensitive).
The default is 0.
