Summary:                    [patch] SendFax function not working as expected on
> 1.6.0.7
Description: 
When trying to send a fax via callfile using T.38 in asterisk version
1.6.0.5 it works fine, but after upgrading to asterisk 1.6.0.7 or newer it
does not work. When receiving re-INVITE from media gateway (Cisco AS-5400)
Asterisk ends call answering 488 Not acceptable here. I am running Asterisk
under Debian kernel 2.6.18-6-686. I am attaching captures both for scenario
which works and scenario which does not work.

---------------------------------------------------------------------- 
With the patch I get an error at the end of the fax, but it works. It might
just be the end of call hangup being reported as an error. I'm using a
Cisco AS5300 gateway and PRI (send and receive).

If T38 is not enabled correctly in sip.conf, but supported I will get the
following error: "Audio loop reports T38 switchover but t38state !=
T38_STATE_NEGOTIATED". It should use the audio codec rather than fail.
