I used this way back for something similar but forget the details
there is a call queue directory you drop files in that can call an  
arbitrary number, and play a recording.

I think for that sort of application though, wouldn't something like
digitemp->snmpd->opennms->pager numbers or sms

be more appropriate ?

the problem I found with the call and play is they build up when the  
calls go unanswered and the whole sequence of things goes to hell.  
Then you get calls when all is well again, etc etc., and it really  
gets annoying when its 3am.

opennms has escalation to page other people if unacknowledged, etc.,  
and can try other contact methods if the initial ones fail.

you also have built in thresholds like certain temperature might be a  
warning, another temperature is critical.
