
[2] Enable Bypass (default)

[3] Events Only = Transparent with Events.
Note: You can also configure this functionality per specific calls,
using IP Profiles (IpProfile_VxxTransportType). For more
information, see 'Configuring IP Profiles' on page 385.
Determines the Bell modem transport method.

[0] = Transparent (default)

[2] = Bypass

[3] = Transparent with events
Determines the device's handling of fax relay upon detection of a
fax CNG tone from originating faxes.

[0] Doesn't send T.38 Re-INVITE = (Default) SIP re-INVITE is
not sent.

[1] Sends on CNG tone = Sends a SIP re-INVITE with T.38
parameters in SDP to the terminating fax upon detection of a
fax CNG tone, if the CNGDetectorMode parameter is set to 1.
Notes:

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 functionality per specific calls, using IP Profiles
(IpProfile_CNGmode). For a detailed description of the parameter
and for configuring this functionality in the IP Profile table, see
'Configuring IP Profiles' on page 385.
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 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.
Defines the number of times that control packets are retransmitted
when using the T.38 standard.
The valid range is 0 to 4. The default is 2.
