dont think that works any more
theres no physical connection between dialer and reciever
and i dont imagne the phone companies will be shipping data over their
lines when they dont have to ;->

the current ones i believe pick the line up and then listen for the beep
depending on the software they can answer, start playing an answering
machine message then click over if they pick up a beep
others will monitor the line when its picked up normally (they detect the
ringing has ended and then pick up) so if a person answers it will listen in
on their conversation and if its a fax it'll answer, (the person presumablly
hangs up at this point)

i tried to implement a system like this where i worked with standard modems
and the like, there was no free sw that was up to acting as answering
machine, fax machine and auto fax pickup.
