Summary:                    [patch] Random Deadlocks maybe in find_call() of
chan_sip. or ast_call() of channel.c
Description: 
I get randomly deadlocks and i'm not sure, what's the reason for that!?!

It is reproducible with the attached test call file, which calls a ring
group with 5-10 extensions. The issue does not occur directly after
restarting asterisk but when there were at least some calls.

Maybe there are two different issues!?!
(backtrace1.txt after random daily deadlock, backtrace2-4.txt after
executing call file)

I have a feeling that the "notifycid=ignore-context" setting is
responsible for that!? All the extensions in the ring group have
subscriptions and generate dialoginfos for snom phones...

Backtrace debug files and test call file attached...
