Name
Valid Range and Description
MGCPDTMFDetectionP
oint
0 = DTMF event is reported on the end of a detected DTMF digit.
1 = DTMF event is reported on the start of a detected DTMF digit (default).
DTMFDigitLength
Time in msec for generating DTMF tones to the PSTN side (if OutOfBandDTMFFormat = 1
or 2).
The default value is 100 msec. The valid range is 0 to 32767.
DTMFInterDigitInterval
Time in msec between generated DTMFs to PSTN side (if OutOfBandDTMFFormat = 1 or
2).
The default value is 100 msec. The valid range is 0 to 32767.
TestMode
0 = CoderLoopback, encoder-decoder loopback inside DSP.
1 = PCMLoopback, loopback the incoming PCM to the outgoing PCM.
2 = ToneInjection, generates a 1000 Hz tone to outgoing PCM.
3 = NoLoopback, (default).
ModemBypassPayloadT
ype
Modem Bypass dynamic payload type.
The valid range is 0 to 127. The default value is 103.
DetFaxOnAnswerTone
0 = Starts T.38 procedure on detection of V.21 preamble (default).
1 = Starts T.38 Procedure on detection of CED fax answering tone.
FaxModemBypassBasic
RtpPacketInterval
0 = set internally (default)
1 = 5 msec
2 = 10 msec
3 = 20 msec
NSEMode
Cisco compatible fax and modem bypass mode
0 = NSE disabled (default)
1 = NSE enabled
Note 1: This feature can be used only if VxxModemTransportType=2 (Bypass)
Note 2: If NSE mode is enabled the SDP contains the following line:
’a=rtpmap:100 X-NSE/8000’
Note 3: To use this feature:
• The Cisco gateway must include the following definition: ‘modem passthrough nse
payload-type 100 codec g711alaw’.
• Set the Modem transport type to Bypass mode (‘VxxModemTransportType = 2’) for all
modems.
• Configure the gateway parameter NSEPayloadType= 100
In NSE bypass mode the gateway starts using G.711 A-Law (default) or G.711µ-Law,
according to the parameter ‘FaxModemBypassCoderType’. The payload type used with
these G.711 coders is a standard one (8 for G.711 A-Law and 0 for G.711 µ-Law). The
parameters defining payload type for the ‘old’ AudioCodes’ Bypass mode.
‘FaxBypassPayloadType’ and ‘ModemBypassPayloadType’ are not used with NSE Bypass.
The bypass packet interval is selected according to the parameter
‘FaxModemBypassBasicRtpPacketInterval’.
NSEPayloadType
NSE payload type for Cisco Bypass compatible mode.
The valid range is 96-127. The default value is 105.
Note: Cisco gateways usually use NSE payload type of 100.
IsCiscoSCEMode
0 = There isn’t a Cisco gateway at the remote side (default).
1 = There is a Cisco gateway at the remote side.
When there is a Cisco gateway at the remote side, the local gateway must set the value of
the ‘annexb’ parameter of the fmtp attribute in the SDP to ‘no’. This logic should be used if
‘EnableSilenceCompression = 2’ (enable without adaptation). In this case, Silence
Suppression should be used on the channel but not declared in the SDP.
BellModemTransportTy
pe
Determines the Bell modem transport method.
0 = Transparent (default).
2 = Bypass.
3 = Transparent with events.
BellcoreCallerIDTypeOn
eSubStandard
Selects the Bellcore Caller ID sub-standard.
0 = Between rings (default).
1 = Not ring related.
