[asterisk-users] Asterisk 13.2.0 Video issues

Hello Matthew,

I have compiled Asterisk 13.2 with the following compiler Flags enabled:

My asterisk is running with the asterisk_script:
root     24048 39.4  2.4 128564 50640 pts/1    Sl   00:02   2:21
/usr/sbin/asterisk -f -vvvg -c

core show locks

=== 13.2.0
=== Currently Held Locks
=== <pending> <lock#> (<file>): <lock type> <line num> <function> <lock
name> <lock addr> (times locked)

When my asterisk crashes there is no file called core.

The results of  gdb -se "asterisk" -ex "bt full" -ex "thread apply all bt"
--batch -c core > /tmp/backtrace.txt

/usr/src/asterisk-13.2.0/core: No such file or directory.
No stack.

What could be the problem ?

Best regards

Both Asterisk 1.6.2 and Asterisk 12 no longer receive bug fixes, so I'm
going to skip past this issue.

Asterisk crashing is a bug. That's a bad thing. Please get a backtrace [1]
and file an issue on the issue tracker [2]. A pcap of the message traffic
would also be very helpful.

I'm going to assume "Asterisk stops" means it crashed as well. If you'd like
to get a backtrace for that as well and attach it to the same issue, that
would be helpful - it may be the same problem that you see with the Bria
phone, or it may be something else.

Well, that's good. :-)

Since there are some that work fine, and some that don't, the trick is going
to be knowing:
(1) How the SIP peers (or PJSIP endpoints) are configured
(2) How the phones are negotiating media with Asterisk

Both your SIP configuration as well as a DEBUG log - generated with trace
logging, showing the negotiation [3] - will be needed to figure out what is
