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 occurring.
