 [0] Disable (Default)
 [1] Enable
In NSE bypass mode, the device starts using G.711 A-Law (default)
or G.711 -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.711 -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.
Gateway Answering Machine

amd-mode
[IpProfile_AmdMode]
Enables the device to disconnect the IP-to-Tel call upon detection of
an answering machine on the Tel side.
 [0] Don't Disconnect = (Default) Device does not disconnect call
upon detection of an answering machine.
