Summary:                    [patch] Deadlock on &(&channels)->lock
Description: 
I've got 2 deadlocks in 3 days. It happens in a peak hours, with more then
a hundred calls in the system.

I've got 2 files 1 with "core show locks" - from the first deadlock (the
day before yesterday), second file - with output from gdb (intho thread,
thread apply all bt, thread apply all bt full) - from today's deadlock.

Yes, looks like it has something to do with Packet2Packet bridging,
if i use X-Lite, instead of Zoiper i don't have a string like:


also "rtp debug" looks different:

Sent RTP packet to      1.1.1.1:19524 (type 08, seq 032384, ts 3420640,
len 000160)

and no rtptimeouts with X-Lite.
