> We have the following scenario:
> 1. Call comes in to [from-internal] context in Asterisk, FastAGI is called.
> 2. While AGI is processing call the caller hangs up. In Asterisk trace we see the CANCEL and a HANGUP received on the channel.
> 3. AGI implements a hunt group by doing Dial() on multiple Local channels, one for each destination.
> 4. Asterisk calls FastAGI for each hunt group destination.
> 5. AGI for each destination does a Dial() to a SIP destination to call telephone.
> 6. Telephones all ring.
> 7. When one telephone answers it's call immediately drops, and the other telephones stop ringing.
> Our question is why the Dial() at step 3, or even at step 5, does not immediately exit (presumably with a DIALSTATUS of CANCEL).
> We do try to detect the hangup within the AGI and exit before doing the Dial(), but however close we get it there's always a chance of a CANCEL being received between our check and the Dial(). But why does the Dial() run instead of immediately exiting?
> Thank you.
