You wouldn't happen to be able to share any of your scripts in that
area, would you, Patrick?

I found this post:
http://forums.athighway.com/index.php?topic=2161.msg6786

...and this one:
http://www.lckdanny.com/blog/?mode=viewid&post_id=96

...both of which seem to handle the specific task of sending a single
notification via phone call.

Once I get that far, then I'm going to have to figure out how to
separate Nagios from the reliable-delivery portion of the process -- I
don't want Nagios waiting on phone calls to connect.  I'm thinking I'd
have it just write each notification as a queue file, then have some
other script handle watching the queue, performing a few retries per
message as needed, warning when there are problems, etc.  This is the
model taken when using qpage -- Nagios' part of the work is very quick,
and the qpage daemon handles the actual delivery, which is slow.
