Exactly. I'm figuring that out. I got some specifications for a Meridian 
system, and they use something called a two-wire TCM (time-compression 
multiplexed) loop at 512kbps.
What I'm investigating is the possibility of detecting on/off hook no matter 
what system.

It should be possible, I remember one recording device that could be plugged 
to any major PBX [digital] system and it would capture the voice data from 
there. But I could be completely wrong.
