You could also hitch up an analog modem to a POTS line, and then let your

You won't hear anything, but the CallerID will let you know that your
monitoring system is *desperately* trying to get in touch :-)
You could take it one step further and get an FXO card and put it in a very
basic asterisk server. Write a simple program which call be pinged with issue
reports as an argument, then pass those arguments to festvox or other TTS
application. Output to WAV, convert to GSM, generate an asterisk call file (or
write an extension) that calls you on the analog line, and plays you the sound
file.
I've done this at several employers. It works fairly well - perhaps better
than it sounds. If you can get a SIP upstream that will let you set your CID,
then send the calls out that route first, and the POTS line becomes a backup -
then if you ever get calls from the POTS DID, you know that you have the
original problem, plus you know that the connection to the SIP gateway is down.

Correct me if I'm wrong, but shouldn't it be possible to grab SMS via
SS7 and feed it into a softswitch or similar like an Asterisk box? All
that would be required would be a friendly SMS provider with an "SMS
peering" or gateway with the network(s) you care about.
I know Verizon was offering a landline VoIP phone that offered SMS long
code support a while ago, but I was never sufficiently interested to
examine it further.
