I am trying to find an auto-dialing modem with call progress tone detection.
Specifically it should be able to sense:
	dial tone
	ringing (at either end)
	busy signal
	reorder signal (circuits busy)
	call waiting tone
It should also be able to sense loop current to check for a dead line
and/or for disconnect.

Anybody know of anything that can do all (or most of) this?
