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.

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.
