We have a package which uses the MultiTech line of modems coupled with
software that will watch files on your network and generate SMS messges =
(or
SNPP, WCTP, TAP, FAX, etc). The underlying engine is a highly customized
version of PageGate software from NotePage, Inc. Part of our =

is in use in numerous Public Safety (Fire/Police/EMS) communications

The Multitech Multimodem GPRS model MTCBA-G-EN-F4 has an ethernet
port. Add a SIM card from your favorite wireless carrier and you can
send and receive SMS messages via "AT" commands over a TCP socket.
Problem is, it seizes up or otherwise founders every few weeks and has
to be power cycled.
Has anyone heard of other products with a good reliability record?

Any pointers on this would be greatly appreciated. I have a need for
geographically redundant access to the same phone numbers in order to
send and receive SMS messages. Even if I have to buy a pair of T1s
that are 99.9% idle, it'd be worth it.
