Um... buy a pager? Paging service is about $120/year. If you
spend one extra day trying to wedge in a more complex solution, it's
not cost-effective. Simple non-email Pager systems can accept/display
touch-tone numeric codes to tell you -what- is wrong.
Since you want to isolate your alert system from network failures
you still are going to be depending upon the phone system.
(what -are- you going to do if\\ when the alert system does down?),
We have vital systems with a web of layered (i.e. piles of partial) solutions...
including the last resort: a RadioShack $99 tape-based, battery-powered
If the rest of the building collapses, a normally-actively-held-open relay
drops out and an off-site phoneline is dialled (three numbers, message
repeats to each).
You could have your system Email you.
If it determined that Email wasn't going to work, it could invoke
a Draconiam system like our final link (or -always- call you with
the canned message to "check your Email"... if you didn't -get- email,
you'd know it was the network)
