Andrew.

Thanks for the reply. I'm using AGI, not DeadAGI. I don't see how I can do post call processing if Asterisk never returns a return code. My script is blocking, waiting on input from stdin, which it never gets. Actually, now that I think about it, what I think is happening, is that when the caller hangs up the call (instead of the callee) Asterisk immediately ceases execution of the script. Now, why would it do that?

There is an AGI command 'CHANNEL STATUS' which you can use to check the status of an open call. If the dial command (even when the caller hangs up) doesn't return a return code to the script until after the call is disconnected, how can I perform a CHANNEL STATUS agi command? The script is still reading from stdin, waiting for a response. Asterisk doesn't send it until the call is disconnected, and which point, my script continues execution and the CHANNEL STATUS command is no longer relevant.

Doug.

It really sounds like you are frustrated because you have assumed a number of 
things about how Asterisk operates instead of testing it and understand what 
the system does and does not do.

Post-call processing is VERY easy to do, and can be done several ways.  You 
can use the 'h' extension, or the 'g' flag to Dial() or also by using 
DeadAGI() instead of AGI().  I'm not sure what you mean by "checking the 
status of an open call with CHANNEL STATUS" but I'll see if anyone else on 
the list can help.

We all get frustrated.  It is best not to broadcast this fact to tens of 
thousands of people.  Collateral damage, and all that.
