[asterisk-users] Roaming callback?

As it says in the book, call files allow calls to be created through  
the Linux shell. If you've used this to create a roaming callback  
service, then you must have created something that allows users to  
submit a phone number to be called back on, after which a .call file  
is created and moved to the /var/spool/asterisk/outgoing/ directory.

> sleep 8s
> mv "$1"  "$2"
> exit 0

This looks like the step that moves the newly created call file to the  
aforementioned directory.

This is what I'm really interested in! How did you manage this? Would  
you be willing to share how you did this?
