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.

Ivan, I'm I have very limited access to my ICQ for the next 3 weeks so it
is not the best way to communicate. Please use email instead.

Ivan and andrew, please try the simple fix - in the transmit_t38 loop
after the
 ast_debug(1, "T38 down, terminating\n");
set res to 0 instead of -1 and see if it fixes anything. Lets leave it
upto the spandsp to decidde if there were error or not and do not force
error conddition ourselves...

Ivan, in ANY case you should NOT rely on dialplan to continue after the
SendFax/ReceiveFax - all post-processing (emailing, saving status to DB
etc) should be done in 'h' extension handler.
