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.

Additional fine tuning, in the situation where 2 callers try to pickup the
same call, previously the failed pickup you hear the errorbeep after the
winner had heard the success beep. Had the pickupsound been tt-weasels, the
pickupfailsound would take some 2-3 seconds before it was played.

Now they play in parallel, well 50ms apart.<pre>[2011-05-04
