Summary:                    T38 Faxing failing on 1.6.1 svn
Description: 
I am attempting to send faxes via t.38 through 2 asterisk servers
i.e
patton -> asterisk 1.6.1 -> asterisk 1.6.1 -> carrier 
what i have noticed is the fax negotiates but no data seems to make it,

when watching the console the below lines appear 
this does not happen on 1.6.1.1 or 1.6.1.2 but does happen on the svn rev
209900
 
the reason for the upgrade is the due to a segfault of ulaw fallback  on 1
carrier i.e issue 15290
Please let me know what log files are required.

Well this is interesting it managed to negotiate and ifp size of 58 and
2400 baud the fax did succeed with SVN-branch-1.6.1-r211958M.
nothing like the ifp 238 and 14400 Baud but 1 step at a time hey.

I have always had it to run t38UDPRedundancy as it is the only one that
has ever worked for me and the asterisk box had it set aswell.
next to that the next issue to get t38 working was for all parties to talk
using the same codec but allowing for failover to ulaw if required.
1 way to improve it would be a force all devices to the same codec if t38
is requested.
