Perhaps I should explain a little further:

I have a system in place based on just under a dozen Multitech GSM
modems in a room by a window. It works... more or less.

It has no provisions for equipment or site failure. The modem breaks,
that number is unavailable. The site fails, that number is
unavailable. The local cell network gets jammed, the number is
unavailable. That's the opposite of "high availability."

So, I need to replace it with something that offers high availability
for each phone number, aka "SMS long code." I realize that the phone
end will still suffer all the vagaries of SMS. But on the base end I
need high availability.

I expect this to cost more than throwing a dozen GSM modems in a room.
I won't be offended when it does.

Anyway, I want to thank everybody for the suggestions, public and
private. You've given me some solid leads I can pursue. I'll let you
know how it turns out.
