Having a network monitoring system send sms pages via email very 
quickly runs into chicken-egg scenario. How do you email a page to 
let the admins know their net has gone down. :-P

AT&T shut down their TAP dialup late last year.
The only method that comes to mind is to buy a GSM modem which has 
SMS messaging capability.

Has anyone done this?

We use a standard modem and pestered Alltel until they gave us the 
secret modem->SMS gateway number.

Nagios includes /usr/local/bin/sms_client.  Fairly simple to use:
Usage: sms_client -v
      sms_client -d
      sms_client [-q][-l loglevel]
                 [service:]number|name[,name|[service:]number...]
                 [message] ...
As long as the monitoring server and the phone lines are working it 
works great.

Nagios is configured to use sms_client:  http://www.smsclient.org/
Works great other than being a royal pain in the rear when a lot of 
things go down and dependencies are not set up in Nagios... I'll fix 
that one of these days :-)
