Okay, I found the problem. This looks like a sofia-sip bug. I made a one line
change to nua_invite_client_ack() function in
libsofia-sip-ua/nua/nua_session.c, as follows:
OLD: assert(cr->cr_method == sip_method_invite);
NEW: assert((cr->cr_method == sip_method_invite) || (cr->cr_method ==
sip_method_bye));
The OLD line was causing a SIGNAL ( 6:SIGIOT/SIGABRT:IOT trap/Abort) for
pthread su_root_run in my phone.
Thanks,
Jerry

My message below got bounced because of size, so I had to chop off the front
end of the trace by about 50KB.

Subject: Segmentation Fault After BYE 407 Proxy Authentication
Hello,
I encountered an su_root_run segmentation fault after a 407 Proxy
Authentication exchange for a BYE message when interfacing with an Avaya server
(this is the only server I've ever seen that requires the BYE to be
authenticated). The trace is below (I have added logging in my local
environment). It looks like the "recv signal r_ack" handling is causing the
fault. Do you know why?
Here is the scenario (the trace below is from phone A):
A calls B
B answers
B holds A
B calls C
Let C ring for 30 seconds
B transfers A to the ringing call C
Disconnect A before C answers
******* segmentation fault at A *******
Thanks,
Jerry
