Valid Range and Description
V34ModemTransportType
(For V.34 & V.90 modems)
(V34 Transport Type)
0 = Transparent
2 = ModemBypass, (default).
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
FaxModemBypassCoderType
(Fax/Modem Bypass Coder Type)
11 = G727_32.
FaxBypassPayloadType
(Fax Bypass Payload Type)
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
(DTMF Volume)
-31 to 0, corresponding to -31 dBm to 0 dBm in 1 dB steps (default = -11 dBm)
DTMF gain control.
DTMFTransportType
(DTMF Transport Type)
0 = erase digit from voice stream, do not relayed 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 send using RFC 2833 standard, but received RFC 2833 digits will
be muted from audio.
MFTransportType
(MF Transport Type)
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
(RFC 2833 Payload Type)
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 AudioCodes proprietary usage.
Cisco™ are using payload type 101 for RFC 2833.
The same payload type should be used for receive and for transmit.
InputGain
(Input Gain)
-31 to 31 corresponding to -31 dB to +31 dB in 1 dB steps. (Default = 1 dB). PCM
input gain.
RTPRedundancyDepth
(RTP Redundancy Depth)
0 = Disable redundancy packets generation (default)
1 = Enable generation of RFC 2198 redundancy packets.
VoiceVolume
(Voice Volume)
-31 to 31, corresponding to -31 dB to +31 dB in 1 dB steps.
(Default = 1 dB). Voice gain control
M
(Packing Factor)
Number of codec payloads (5,10, 20 or 30 msec, depending on selected codec) to
be used for generating one RTP packet.
M = n payloads (n = 1, 2 or 3); M = 1 (default)
SCE
(Silence Suppression)
0 = silence compression disabled (default)
1 = silence compression enabled
ECE
(Echo Canceller)
0 = Echo Canceler disabled
1 = Echo Canceler Enabled (default)
IPDiffServ
(RTP IP Diff. Serv)
0 – 63 value for setting the Diff Services Code Point (DSCP).
If defined it will override the IP TOS and IP Precedence settings.
Applies only to RTP packets
IPPrecedence
(RTP IP Precedence)
0 to 7 (default 0)
Sets the value of the IP precedence field in the IP header for all RTP packets
IPTOS
(RTP IP TOS)
0 to 15 (default 0)
Sets the value of the IP Type Of Service field in the IP header for all RTP packets
FlashHookPeriod
300 to 1500 (default 700) Flash Hook time in msec. The parameter is used for Flash
Hook detection in MP-1xx/FXS and for Flash Hook generation in MP-1xx/FXO
Gateways.
