[AusNOG] CLI SIP utility?

[Ross Wheeler]

Might seem like a strange request, but here goes anyway!

Does anyone know of a small, simple, command-line utility that can simply 
connect to a VoIP service, make a call and either play a wav/mp3 file or 
(even nicer) text-to-voice, then terminate?

There are plenty of GUI things, things that run in windows etc - I just 
want a small utility that can run on a remote freeBSD or linux box and can 
call (via an existing SIP account) for assistance if certain conditions 
exist.

pjsip looks like it might almost sortof-kindof do it, but it's unclear if 
it can automatically dial and deliver a message without some sort of 
external scripting.

I'm sure it'd be a very useful tool, everything from calling for help if 
disks fill up, environmental conditions turn to crap, power loss, fire, 
break-in, low fuel, battery fail...

Yes, I could use asterisk (and do on some sites), but that seems like a 
whole lot of extra baggage than is required for the (simple) task at hand.

TIA,
R.
