Rusty Newton commented on ASTERISK-25307:
-----------------------------------------

"should" - I got derailed into other things. I'll do my best to look at this tomorrow David. Thanks. 

I'm pretty sure competing projects send back the other issue reporters from the future to side-track me. Just a hunch though.

> 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.
