Lee would be the guy to ask, seeing as he is involved (deeply  
involved, I think) in HylaFAX development. AFAIK, HylaFAX does  
require a DSP, but IAXModem is designed to function as the DSP,  
thereby allowing HylaFAX to take calls that come in via asterisk  
without additional hardware (such as a T1 fax-modem, a crossover  
cable and a multi-port T1 card, as Lee suggested.).

No, software vs hardware isn't the point. As Lee mentioned, there are  
many problems with the hardware side of things, too. What I am  
asserting is that Asterisk's fax capabilities are an inferior choice  
to HylaFAX at this time. Maybe in a year or two that will no longer  
be the case. Also, once Lee has some time to develop IAXModem  
further, I bet it will be a great option, and it is software based.
