Yuck!

I assume that you only need to kill the diald when making PSTN calls.
Then again, that's probably how you make the bulk (if not all) of your
calls, considering your limited bandwidth. :-)

Rather than scanning the CDR somehow, perhaps you should use the 'h'
extension to detect the hangup.  You can run an AGI or System from
there to do whatever you need.

You could get fancy and create some sort of lock file to prevent
Asterisk from dialling out while the restart AGI is running.  The
"kill diald" script could check for the lock file and either wait or
die.  The "restart diald" script could create a file wile processing
and delete when done.

Just to reiterate my earlier point - yuck! :-)
