Description
Note: The corresponding global parameter is
CNGDetectorMode.
Defines the modem transport type.
■ [-1] = (Not Configured) The settings of the global
parameters are used:
✔
V21ModemTransportType
✔
V22ModemTransportType
✔
V23ModemTransportType
✔
V32ModemTransportType
✔
V34ModemTransportType
■ [0] Disable = Transparent.
■ [2] Enable Bypass (Default)
■ [3] Events Only = Transparent with Events.
For a detailed description of the parameter per modem
type, see the relevant global parameter (listed above).
Enables Cisco's compatible fax and modem bypass mode,
Named Signaling Event (NSE) packets.
■ [0] Disable (default)
■ [1] Enable
In NSE bypass mode, the device starts using G.711 A-Law
(default) or G.711Mu-Law, according to the
FaxModemBypassCoderType parameter. The payload
type for these G.711 coders is a standard one (8 for G.711
A-Law and 0 for G.711Mu-Law). The parameters defining
payload type for the 'old' Bypass mode
FaxBypassPayloadType and ModemBypassPayloadType
are not used with NSE Bypass. The bypass packet interval
is configured according to the
FaxModemBypassBasicRtpPacketInterval parameter.
The SDP contains the following line:
a=rtpmap:100 X-NSE/8000
Note:
■ When enabled, the following conditions must also be
met:
✔
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 is set to 2) for all
modems.
✔
Set the NSEPayloadType parameter to 100.
■ The corresponding global parameter is NSEMode.
