0 = Disable (default).
1 = Event Only (N/A).
2 = Relay. T.38 fax relay session is initiated by the originating fax if 'IsFaxUsed =
1'. Note that using this mode isn't recommended.
Number of (20 msec) coder payloads that are used to generate a fax/modem
bypass packet.
You can enter a value of 1, 2 or 3 coder payloads.
The default value is 1 coder payload.
Determines the fax bypass RTP dynamic payload type.
The valid range is 96 to 120. The default value is 102.
Modem Bypass dynamic payload type (range 0-127).
The default value is 103.
0 = Starts T.38 procedure on detection of V.21 preamble (default).
1 = Starts T.38 Procedure on detection of CED fax answering tone.
0 = set internally (default)
1 = 5 msec (not recommended)
2 = 10 msec
3 = 20 msec
0 to 150 msec (default=40)
Determines the Jitter Buffer delay during fax and modem bypass session
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'.
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.
V.22 Modem Transport Type that the gateway uses.
You can select:
0 = Transparent
2 = Modem Bypass (default).
V.23 Modem Transport Type that the gateway uses.
You can select:
0 = Transparent
2 = Modem Bypass (default).
V.32 Modem Transport Type that the gateway uses.
You can select:
0 = Transparent
2 = Modem Bypass (default).
Note: This option applies to V.32 and V.32bis modems.
