Description
Silence Suppression is a method conserving bandwidth on VoIP calls by not
sending packets when silence is detected.
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).
Note: If the selected coder is G.729, the following rules determine the value
of the 'annexb' parameter of the fmtp attribute in the SDP.
EnableSilenceCompression = 0
EnableSilenceCompression = 1
EnableSilenceCompression = 2 and IsCiscoSCEMode = 0
EnableSilenceCompression = 2 and IsCiscoSCEMode = 1
Off [0] = Echo Canceler disabled.
On [1] = Echo Canceler enabled (default).
DTMF Mute [0] = Erase digits from voice stream, do not relay to
remote.
Transparent DTMF [2] = Digits remain in voice stream.
RFC 2833 Relay DTMF [3] = Erase digits from voice stream, relay to
remote according to RFC 2833 (default).
Note: This parameter is automatically updated if one of the following
parameters is configured: TxDTMFOption or RxDTMFOption.
N/A.
DTMF gain control value in dB (to the TDM side).
The valid range is -31 to 0 dB.The default value is -11 dB.
N/A.
N/A.
N/A.
N/A.
Determines the Answer Detector sensitivity.
The range is 0 (most sensitive) to 2 (least sensitive). The default is 0.
0 = Disable CAS relay (default).
1 = Enable CAS relay mode using RFC 2833.
The CAS relay mode can be used with the TDM tunneling feature to enable
tunneling over IP for both voice and CAS signaling bearers.
