ƒ
[0]

Notes:

This feature can be used only if VxxModemTransportType = 2
(Bypass).
ƒ
If NSE mode is enabled, the SDP contains the following line:
'a=rtpmap:100 X-NSE/8000'.
ƒ
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 device starts using G.711 A-Law
(default) or G.711
μ
-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.
