[Asterisk-Dev] How can receive frames of all channels?

[Brian West]

I think app_queue has state thread to track device states (why this  
wasn't put into the core.. is anyones guess).  Might wanna check  
cli.c see how "show channels" is performed and is a good place to get  
a example on how to get the list of channels... and as always,  
locking locking locking...
