Parameter
Description
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'.
Web: Echo Canceler
EMS: Echo Canceller Enable
[EnableEchoCanceller]
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.
EMS: Echo Canceller Hybrid Loss
[ECHybridLoss]
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
[ECNLPMode]
Defines the echo cancellation Non-Linear Processing (NLP)
mode.
[0]
= NLP adapts according to echo changes (default).
[1]
= Disables NLP.
[EchoCancellerAggressiveNLP]
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.
Web: Enable RFC 3389 CN
Payload Type
EMS: Comfort Noise Enable
[EnableStandardSIDPayloadType]
Determines whether Silence Indicator (SID) packets are sent
according to RFC 3389.
[0]
Disable = G.711 SID packets are sent in a proprietary
method (default).
[1]
Enable = SID (comfort noise) packets are sent with the
RTP SID payload type according to RFC 3389. Applicable
to G.711 and G.726 coders.
[RTPSIDCoeffNum]
Determines the number of spectral coefficients added to an
SID packet being sent according to RFC 3389. Valid only if
EnableStandardSIDPayloadType is set to 1.
The valid values are
[0]
(default),
[4]
,
[6]
,
[8]
and
[10]
.
