Summary:                    [patch] [regression] Call Pickup Hangs Asterisk
(deadlock?)
Description: 
Asterisk stops to service new calls when someone tries to pickup a call by
pressing *8. Some existing calls are also terminated, although others
continue to work. I still can run any command in the console, but I can't
stop or kill Asterisk. I can kill it only with -9 flag.
I found this trouble in versions 1.8.1, 1.8.2 and SVN.

Got this trouble too. My configuration is FreeBSD 8.1-STABLE, asterisk
1.8.3.2 from ports, as well as 1.8.0 (from ports also).
In my configuration peers are allowed to use only g711a and g711u codecs.
The only noticeable messages on console was bunch of messages like can't
convert beep.gsm to existing codec.
There was no deadlocks or system locks, asterisk just were ending with
message "Asterisk ended (0)"
I fixed this trouble initially by disabling call pickup in group and
allowing only directed pickup from queue. But after all, I tried to convert
beep.gsm to alaw and ulaw format, and enabled group pickup back - it
worked.
Quote from my dialplan regarding pickups:
exten => *,1,PickUP(queue-number)
exten => *,2,PickUP()
