Exactly! I catch that today too.
I have t38pt_udptl=yes in global section in sip.conf, t38pt_udptl=yes for
one endpoint and t38pt_udptl=no for endpoint which calls cause asterisk
crash.
When I set t38pt_udptl to yes asterisk stop crashes.
Unfortunately it's very difficult to make debug build because its
production environment with many sip endpoints, but I try do something to
accomplish your requirement.
Thanks!
