Thread: [Asterisk-java-users] Timeout when hanging up

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

I'm trying something which is probably a little unusual.
Basically I want to check if a number is inservice or out of service.
I do this by dialing the number and if it rings I instantly drop the 
connection by hanging up.

The code basically works fine however the hangup action is throwing a 
timeout even though the line is successfully hung up.
Even if I set the time to 30 seconds a timeout still occurs, where as 
the sip phone I'm dialing hangs up immediately.

Interestingly as soon as the hangup times out I get a HangupEvent.

So I thought it might be worth posting the code here for inspection and 
comment.
