Hi all, I configure ser to forward a call to Asterisk when callee is busy or unanswered. But, when the call is forwarding and the caller cancels the call, ser still forward the call to Asterisk and won't cancel the call. How do I really cancel the call and stop forwarding to Asterisk? I will be appreciate for any help! Here are my ser.cfg: # $Id: nat-rtpproxy.cfg 9 2005-08-19 15:30:55Z /CN=Greger V.
