Completition of Calls to busy Subscriber

Is this like an auto-redial?

I guess the method would be if you call someone, and it's busy, you can press a feature code to have it automatically redial that person on regular intervals. This seems like a feature the phone itself should implement, but there's no real reason it couldn't be done.

It would just have to create a scheduled call file (set file time to some point in the future on a file in the /var/spool/asterisk/outgoing directory) - this file would probably have to be generated via AGI. It would ring the caller, and when they pick up, immediately retry the extension.

It may be more useful to combine with an IVR so it prompts "To automatically redial this call in 10 minutes, press 1" on busy, or "Redialing 3 more times, to cancel redial attempts, press 7" after trying to redial and still getting busy.
