Well...

I examined these Q931 traces and I don't see anything different between the failed call and the successful call. I would hop into #freetdm on irc.freenode.net and see if moy is around. He might be able to shed some light on this. If it's not occurring at the libpri level then he might be able to help figure out if FreeTDM is not behaving properly.

Hi Guys.

Current setup is a FS box with a Digium TE122 installed, with DAHDI kernel drivers and using FreeTDM with a libpri span...

And finally some logs from two calls, a successful one, and a failed one...

If anyone could offer any suggestions as to what I can do to answer every incoming call into the box that would very appreciated. Of course if I need to provide more information I am willing to, and any suggestions for settings that need changing to test out will also be great.

Thank you in advance
Matt
