FYI here is one view of one of the threads I was recalling: http://www.gossamer-threads.com/lists/nanog/users/104612?search_string=sms;# 104612 Make sure to look at post #5 that summarized a previous thread too. I think the "direct connection" I was thinking of was the modem to TAP gateway options. -Scott -----Original Message----- From: wherrin () gmail com [mailto:wherrin () gmail com] On Behalf Of William Herrin Sent: Tuesday, September 22, 2009 12:29 PM To: Scott Berkman Cc: nanog () nanog org Subject: Re: SMS On Tue, Sep 22, 2009 at 11:59 AM, Scott Berkman <scott () sberkman net> wrote:
Some people use a serial interface to a specific model cell phones to directly send the message over the carrier's cellular network. This is

in the event of isolation of a location from any IP connectivity to a carrier gateway.
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?
I believe there was another solution that involved direct carrier connections, but these are most likely cost prohibitive in most
situations. 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. Regards, Bill Herrin -- William D.
