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.

---------------------------------------------------------------------- 
Both patches work for me, but have the same problem which may be an issue
elsewhere in the code. If T38 is enabled for the Peer but not in Global T38
is selected but fails. I guess this is not a big deal.

Adding the wait before calling FAX (I tried 1-4 seconds) did not help with
T38, the added wait even made some faxes fail with audio mode.
