I'm not sure where you got that idea. Most comments about iaxmodem + 
HylaFAX are very positive. It does, of course, require a reliable 
connection between iaxmodem and the PSTN, but most people set these 
things up in a reasonably well controlled environment. There are some 
notes at http://www.soft-switch.org/spandsp-soft-fax-performance.html 
about the results of serious real world volume testing of iaxmodem.
