Valid Range and Description
V22ModemTransportType
[V.22 Modem Transport Type]
V.22 Modem Transport Type that the gateway uses.
You can select:
0 = Disable (Transparent)
1 = Enable Relay -- N/A
2 = Enable Bypass -- default
3 = Events Only (Transparent with Events)
V23ModemTransportType
[V.23 Modem Transport Type]
V.23 Modem Transport Type that the gateway uses.
You can select:
0 = Disable (Transparent)
1 = Enable Relay -- N/A
2 = Enable Bypass -- default
3 = Events Only (Transparent with Events)
V32ModemTransportType
[V.32 Modem Transport Type]
V.32 Modem Transport Type that the gateway uses.
You can select:
0 = Disable (Transparent)
1 = Enable Relay -- N/A
2 = Enable Bypass -- default
3 = Events Only (Transparent with Events)
Note: This option applies to V.32 and V.32bis modems.
V34ModemTransportType
[V.34 Modem Transport Type]
V.90 / V.34 Modem Transport Type that the gateway uses.
You can select:
0 = Disable (Transparent)
1 = Enable Relay -- N/A
2 = Enable Bypass -- default
3 = Events Only (Transparent with Events)
InputGain
[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.
The default value is 0 dB.
RTPRedundancyDepth
[RTP Redundancy Depth]
0 = Disable redundancy packets generation (default)
1 = Enable generation of RFC 2198 redundancy packets.
RFC2198PayloadType
RTP redundancy packet payload type, according to RFC 2198.
The range is 96-127. The default is 104.
Applicable if ‘RTPRedundancyDepth=1’
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’.
