Parameter Description
Voice Volume
[VoiceVolume]
Voice gain control (in decibels). This parameter sets the level for
the transmitted (IP-to-Tel) signal.
The valid range is -32 to 31 dB. The default value is 0 dB.
Input Gain
[InputGain]
Pulse-code modulation (PCM) input gain control (in decibels).
This parameter sets the level for the received (Tel-to-IP) signal.
The valid range is -32 to 31 dB. The default value is 0 dB.
Silence Suppression
[EnableSilenceCompression]
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 following rules determine
the value of the 'annexb' parameter of the fmtp attribute in the
SDP:
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'.
Echo Canceler
[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.
DTMF Transport Type
[DTMFTransportType]
Determines the DTMF transport type.
[0] DTMF Mute = Erases digits from voice stream and doesn't
relay to remote.
[2] Transparent DTMF = Digits remain in voice stream.
[3] RFC 2833 Relay DTMF = Erases digits from voice stream
and relays to remote according to RFC 2833 (default).
[7] RFC 2833 Relay Rcv Mute = DTMFs are sent according to
RFC 2833 and muted when received.
Note: This parameter is automatically updated if one of the
following parameters is configured: TxDTMFOption or
RxDTMFOption.
