Yes, look carefully at the line I gave you with the sleep:

os.execute("(sleep 2;mv /var/tmp/callback.call /var/tmp/asterisk/outgoing)&")

The important parts are the ( before the sleep and the )& at the end. The
brackets create a subshell to do the sleep and move, and the & puts that
subshell in the background, so the os.execute will return immediately
without waiting for the sleep to execute. By the time the mv is executed,
the channel should have been hung up properly.

Cheers
