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 this 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 this
parameter and for configuring this functionality in the IP Profile
table, see ''Configuring IP Profiles'' on page 314.
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: 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.
Notes:

For this parameter to take effect, you must reset the device.

When the device is configured to use V.152 to negotiate audio
and T.38 coders, the UDP port published in SDP for RTP and
for T38 must be different. Therefore, set the T38UseRTPPort
parameter to 0.
