[Input Gain]
PCM input gain control in dB. This parameter sets the level for the received
(PSTNÆIP) signal.
The valid range is -32 to 31 dB.
The default value is 0 dB.
Note: This parameter is intended for advanced users. Changing it affects
other gateway functionalities.
VoiceVolume
[Voice Volume]
Voice gain control in dB. This parameter sets the level for the transmitted
(IPÆPSTN) signal.
The valid range is -32 to 31 dB.

EnableSilenceCompression
[Silence Suppression]
The parameter SCE is used to
maintain backward compatibility.
0 = Silence Suppression disabled (default).
1 = Silence Suppression enabled.
2 [Enable without adaptation] = 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.
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 Æ ‘annexb=no’.
EnableSilenceCompression = 1 Æ ‘annexb=yes’.
EnableSilenceCompression = 2 and IsCiscoSCEMode = 0 Æ
‘annexb=yes’.
EnableSilenceCompression = 2 and IsCiscoSCEMode = 1 Æ ‘annexb=no’.
