Description
Note:
■ This feature is applicable only if the
IsFaxUsed parameter is set to [1] or
[3].
■ The device also sends T.38 re-
INVITE if the CNGDetectorMode
parameter is set to [2], regardless of
the FaxCNGMode parameter
settings.
Global parameter that enables the
detection of the fax calling tone (CNG)
and defines the detection method. You
can also configure this feature per
specific calls, using IP Profiles
(IpProfile_CNGmode). For a detailed
description of the parameter and for
configuring this feature in the IP Profiles
table, see Configuring IP
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 a timeout (in msec) for detecting
fax from the Tel side during an
established voice call. The interval starts
from when the voice call is established.
If the device detects a fax tone within the
interval, it ends the voice session and
sends a T.38 or VBD re-INVITE
message to the IP side and processes
the fax. If the interval expires without any
received fax event, the device ignores all
subsequent fax events during the voice
session.
The valid value is 0 to 120000. The
default is 0. If set to 0, the device can
detect fax during the entire voice call.
Note: The parameter is applicable only to
the Gateway application.
Defines the T.38 fax relay version.
■ [-1] Not Configured = (Default) No
T.38
■ [0] Version 0
■ [3] Version 3 = T.38 Version 3 (V.34
over T.38)
