Description
■ [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
feature per specific calls, using IP
Profiles (IpProfile_NSEMode). For a
detailed description of the parameter and
for configuring this feature in the IP
Profiles table, see Configuring IP
Profiles.
Note: If this feature 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 maximum size of a T.38
datagram that the device can receive.
This value is included in the outgoing
SDP when T.38 is used.
The valid range is 120 to 600. The default
is .
Determines when the device initiates a
T.38 session for fax transmission.
