fax CNG tone or a V.34/Super G3 V8-CM (Call Menu) signal 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.

[2] Sends on CNG or v8-cn = 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)
or upon detection of a V8-CM signal.
Note:

If the parameter is set to [2] and the CNGDetectorMode
parameter is set to [0], the device sends a re-INVITE only if it
detects a V8-CM signal from the originating fax.

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.
CNG Detector Mode
configure voip > media fax-
modem > coder
[CNGDetectorMode]
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 Profiles on page 404.
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.
