|>How exactly do they differentiate between a fax call and a voice call?

well it's quite simple, in fact the phone company has had the technology for
years, the listen for a carrier of 2600 KHz (or something in that area).  In 
the past they used this information to turn off full duplex on fone lines 
because the lag time for long distance comm. would screw up transmission.  
Lately, there's a controversy over BBS's paying business rates because they
charge their users, the Ma Bell would use this listening in such a case.
