In general in the terminology for this stuff "supervised" just means the 
system its referring to not only knows when something bad is happening, 
it also is constantly told everything is ok, and timing out waiting for 
that ok is also an indication of a problem.

There is nothing magic about it and there are many different ways it can 
be accomplished on various media that all satisfy the regulations, but 
in general a dialup on demand connection whether it be voip or copper 
does not satisfy "supervised" as a requirement.

Contact ID is just one protocol, fsk is another that is basically 
modemlike. Most alarms can be configured for a handful of protocols.

There is even a channel for asterisk made for receiving one of them (I 
forget which) and I think its nextalarm.com that is using it for their 
monitoring with voip boxes.
