I get so few faxes that I could not justify spending the extra money on 
a fax line.  I'd be better off subscribing to one of the online fax 
services if I have to go that route.  I never really had a problem with 
vgetty answering the line and determining if it was a fax or voice call. 
 That's why I thought if vgetty was doing the answering and handing off 
to hylafax, I'd be better off.  Maybe not though from what you're saying.

I guess I could just buy a second modem and one of those automatic fax 
switch devices.  I'm just trying to keep the total package small and the 
cost down.
