notify by telephone call?

[Furnish, Trever G]

Thanks, Shadih.  I agree with you that it's not a great idea (although with enough work and loving care, I think pagerduty.com is likely to be a hit), and I don't relish the idea of leaving voicemail messages for folks, but I'm going to at least give it a shot.  I will also continue sending email notifications for every alert.

I learned long ago that even for text paging, it's always best to send an email copy of every text page -- it helps greatly to avoid folks blaming Nagios when the real problem is their carrier.

Any other suggestions from anyone?

Twinkle has a command line and it should be easy to handle via script.  However I have to say making a phone call for notification is not a good idea.  People miss call all the time.  Paging is much more reliable then placing a call..  That is just my two cents

Can anyone whose already done this point me in the right direction for

The hard part isn't the text-to-speech (I'm assuming I can just use
festival for that), or even a pre-recorded message.

What's proving to be the hard part for me is figuring out how to
reliably make a phone call.  We have an existing VoIP phone system,
including Cisco routers I could connect to using SIP... if I could find
a good command-line SIP calling tool.

I also don't want to create a notification method that causes Nagios to
back up on notifications.  The existing notification methods allow
Nagios to quickly hand off notifications to other daemons that ensure
reliable delivery (QuickPage, which is wonderful for sending SMS via TAP
gateways, and sendmail, which of course handles sending out
notifications by email).  But I don't want to get distracted by this --
if I could just find a good command-line
"place-a-call-and-play-some-audio-into-it" tool, I could wrap it easily
in enough scripting to make it reliable.

So far I've found notes on using vgetty (and I'm still reading through
those), and I've found notes on doing this with Asterisk (but I don't
have Asterisk and I hope it's an unneeded level of complexity).  There
are lots of graphical sip clients available, but I haven't found any
others to use from the command-line yet.

Suggestions?
