Modem as a service?

Nah, it wasn't you! :)
The solution I think we're going to go with is leveraging our existing SIP infrastructure and write scripts to dial out to the OOB Modem / Fax machines at the sites that are disconnected from the network. If they both don’t answer, we'll assume a power outage. If one or the other does answer, it'll queue up for human interaction.
I wrote a script in Perl in about 15 minutes to do this. God, I'm not sure if I'm stuck thinking inside or outside the box anymore!
Thanks for the replies and insights,

I must be thick - how does that solve the problem? The OP wants to know if a modem at a remote site will answer the phone. Maybe I misunderstood the problem.
