[Asterisk-Dev] Is the ChanIsAvail command thread safe?

[Carlos Antunes]

Kevin,

Is there any mechanism currently on asterisk to "reserve" channels without 
actually dialing them? I'm going to look at the code for Dial and 
ChanIsAVail to see if a simple patch is possible but your guidance would be 
invaluable.

Thanks!

Carlos
