V22ModemTransportType 0 = Transparent
2 = ModemBypass, (default).
V23ModemTransportType 0 = Transparent
2 = ModemBypass, (default).
V32ModemTransportType
(For V.32 & V.32bis modems)
0 = Transparent
2 = ModemBypass, (default).
V34ModemTransportType
(For V.34 & V.90 modems)
0 = Transparent
2 = ModemBypass, (default).
FaxModemBypassCoderType Coder to be used while performing fax/modem bypass. Refer to acTCoders
enumeration. Usually, high bit rate coders such as G.711 and G.726/G.727
should be used.
0 = G711 A-law =0, (default)
1 = G711
µ
-law=1,
4 = G726_32
11 = G727_32.
FaxBypassPayloadType Fax Bypass RTP dynamic payload type
Default = 102
T38ProtectionMode 0 = Use redundancy packets for protecting T.38 fax relay stream, (default)
1 = Use Forward Error Correction (FEC) algorithm to protect T.38 fax relay
stream (isn’t implemented)
DTMFVolume -31 to 0, corresponding to -31 dBm to 0 dBm in 1 dB steps (default = -11 dBm)
DTMF gain control.
DTMFTransportType 0 = erase digit from voice stream, do not relay to remote.
1 = erase digit from voice stream, relay to remote. (Default)
2 = digits remains in voice stream.
3 = erase digit from voice stream, relay to remote according to RFC 2833
standard
7 = digits will be sent using RFC 2833 standard, but received RFC 2833 digits
will be muted from audio
MFTransportType 0 = erase MFs from voice transport, not relayed to remote.
1 = erase MFs from voice transport, relay to remote. (Default)
2 = MFs are not erased from voice, not relayed to remote.
RFC2833PayloadType The RFC 2833 DTMF relay dynamic payload type.
Range: 96 to 99, 106 to 127; Default = 96
The 100, 102 to 105 range is allocated for proprietary usage.
Cisco™ are using payload type 101 for RFC 2833.
The same payload type should be used for receive and for transmit.
InputGain -31 to 31 corresponding to -31 dB to +31 dB in 1 dB steps. (Default = 1 dB). PCM
input gain.
RTPRedundancyDepth 0 = Disable redundancy packets generation (default)
1 = Enable generation of RFC 2198 redundancy packets.
VoiceVolume -31 to 31, corresponding to -31 dB to +31 dB in 1 dB steps.
(Default = 1 dB). Voice gain control
SCE 0 = silence compression disabled (default)
1 = silence compression enabled
