Summary:                    [patch] faxing with T.38 fails
Description: 
I have asterisk 1.4.26.1 setup with T.38 passthrough. I have linksys 2102
ATA and my provider use Cisco gateway with T.38 support enabled. Everytime
I send fax this fail with no apparent reason. 
In sip debug logs it looks that T.38 negotiation was successfull, later I
receive SIP BYE packet from provider and the call si hangup but no fax is
sent.

OK, here's another patch to try; you'll have to revert the previous patch
for this one to apply, as it touches the same code (and more).

When you run this test, I'll need both the packet capture *and* the full
Asterisk log (including 'set verbose 10', 'set debug 10', 'sip debug on'
and 'rtp debug on') so that I can see how the packets going in and out
relate to the processes in the Asterisk code. Thanks.
