Version 7.2
Defines the modem bypass output gain control.
The range is -31 dB to +31 dB, in 1-dB steps. The default is 0 (i.e.,
no gain).
Defines the basic frame size used during fax/modem bypass
sessions.

[0] = (Default) Determined internally

[1] = 5 msec (not recommended)

[2] = 10 msec

[3] = 20 msec
Note: When set to 5 msec (1), the maximum number of
simultaneous channels supported is 120.
Defines the Jitter Buffer delay (in milliseconds) during fax and
modem bypass session.
The range is 0 to 150 msec. The default is 40.
Enables in-band network detection related to fax/modem.

[0] = (Default) Disable.

[1] = Enable. When the parameter is enabled on Bypass and
transparent with events mode (VxxTransportType is set to 2 or 3),
a detection of an Answer Tone from the network triggers a switch
to bypass mode in addition to the local Fax/Modem tone
detections. However, only a high bit-rate coder voice session
effectively detects the Answer Tone sent by a remote endpoint.
This can be useful when, for example, the payload of voice and
bypass is the same, allowing the originator to switch to bypass
mode as well.
Global parameter that enables Cisco's compatible fax and modem
bypass mode, Named Signaling Event (NSE) packets. You can also
configure this functionality per specific calls, using IP Profiles
(IpProfile_NSEMode). For a detailed description of the parameter
and for configuring this functionality in the IP Profiles table, see
''Configuring IP Profiles'' on page 393.
Note: If this functionality is configured for a specific IP Profile, the
settings of this global parameter is ignored for calls associated with
the IP Profile.
Defines the NSE payload type for Cisco Bypass compatible mode.
The valid range is 96-127. The default is 105.
Note:

The parameter is applicable only to the Gateway application.

Cisco gateways usually use NSE payload type of 100.
Defines the port (with relation to RTP port) for sending and receiving
T.38 packets.

[0] = (Default) Use the RTP port +2 to send/receive T.38 packets.

[1] = Use the same port as the RTP port to send/receive T.38
packets.
