well here's a question - which is more reliable ?
- a single copper line dialed on demand when there is a problem
- voip or other internet technology, using internet connections on more 
than one media (say phone and cable), voip connected to multiple servers 
in a failover configuration.

its not uncommon for even a house to have multiple internet connections, 
but how many buildings have phone lines that connect back to different 
CO's and fail over ?

The best bet if you really care about what you are trying to protect is 
make sure the message can get out as many ways as possible, whether it 
be phone, voip, network, cellmodem, etc. Forget what regulations 
require, no one says you can't go further than the minimum if you want.
