Summary:                    Sip channels lock
Description: 
When I type "show channels", I can see many locked sip channels, that never
hangup. The "soft hangup" command doesn't work.

[macro-TRUNK0]
exten => s,1,NoOp()
exten => s,2,MixMonitor(${CDR(uniqueid)}.wav,v(3)V(3))
exten => s,3,Dial(${ARG1}${ARG2},80,kKftThH)
exten => s,4,Hangup()

exten => h,1,Hangup

- This is a bug, if you look at show channels output you can see, the
extension 3021 holds 6 channels.

- There are 16 agents, so max simultaneous should be 16, but there are
33.

- The problem is , when such garbage channels pile up, they take the
system resources and rtp bandwidth. So later it becomes impossible to make
a stable call. It's possible dial a number but when line is bridged there
is no audio.

- This locked channels cannot be cleaned. even with "soft hangup"
command.
The only way to return back system is to restart the asterisk.

- So this problem is somehow related to similar bug
