Determines the Answer Detector sensitivity.
The range is 0 (most sensitive) to 2 (least sensitive). The
default is 0.
Silence Suppression is a method for conserving bandwidth on
VoIP calls by not sending packets when silence is detected.
[0] Disable = Silence Suppression is disabled (default).
[1] Enable = Silence Suppression is enabled.
[2] Enable without Adaptation = A single silence packet is
sent during a silence period (applicable only to G.729).
Note: If the selected coder is G.729, the value of the 'annexb'
parameter of the fmtp attribute in the SDP is determined by
the following rules:
If EnableSilenceCompression is 0: 'annexb=no'.
If EnableSilenceCompression is 1: 'annexb=yes'.
If EnableSilenceCompression is 2 and IsCiscoSCEMode is
0: 'annexb=yes'.
If EnableSilenceCompression is 2 and IsCiscoSCEMode is
1: 'annexb=no'.
Determines whether echo cancellation is enabled and
therefore, echo from voice calls is removed.
[0] Off = Echo Canceler is disabled.
[1] On = Echo Canceler is enabled (default).
Note: This parameter is used to maintain backward
compatibility.
Sets the four wire to two wire worst-case Hybrid loss, the ratio
between the signal level sent to the hybrid and the echo level
returning from the hybrid.
[0] = 6 dB (default)
[1] = N/A
[2] = 0 dB
[3] = 3 dB
Defines the echo cancellation Non-Linear Processing (NLP)
mode.
[0] = NLP adapts according to echo changes (default).
[1] = Disables NLP.
Enables or disables the Aggressive NLP at the first 0.5 second
of the call. When enabled, the echo is removed only in the first
half a second of the incoming IP signal.
[0] = Disable (default)
[1] = Enable
Note: For this parameter to take effect, a device reset is
required.
