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.

lmaidsen, mmichelson,
I believe we should proceed with committing the patch because at least if
fixes the "T38 fax termination completely non-working" issue.

The changes in chan_sip Ivan proposing can take unpredictable time from
him to implement. And these changes will add nioe-to-have feature not fix
the bug explained here.
