I'm at a large site, 2500+ employees, 800 monitored hosts (several thousand farm machines that are only monitored in aggregate) and a few petabytes of storage.
We feel we need to get every message from our monitoring system (GroundWork/Nagios at the moment, but we're migrating off of that). We used to use a pair modem directly connected to the monitoring system that could send pages via. TAP/IXO. As we have migrated to cell phones instead of pagers, we have found that more and more of them are not supporting TAP gateways. Our current setup varies depending on where it is. In our India office we have a server with an SMS modem and kannel. It is mostly reliable but we occasionally run into issues where kannel thinks it is working but loses the ability to talk to the modem. We haven't found a good way to catch this happening short of sending heartbeat SMS messages which would drive whoever gets them crazy. In the US we have started deploying the iSMS appliance from MultiTech (formerly known as the SMSFinder). It is an integrated SMS modem and web server with an API that you can use to send messages. Check Linux Journal, there was a good article there last year on setting one up complete with a set of scripts that integrate with Nagios for monitoring and sending messages. We have found SMS to be very reliable. As far as we know we haven't lost any messages. We do have a handful of devices that we have to notify via. e-mail, those don't lose messages but we have experienced significant delays in getting them.
