I'd like you to do one thing for me so that I can better see what is
wrong. There have been a significant number of updates to libss7 since
the version you are running. Can you update libss7 and reinstall it,
then update asterisk-trunk, and reinstall it, and then get me a trace of
the call? The outputs should be a LOT clearer now, I have done a lot of
work on making the debug more useful.
Thanks.
