My personal experience -  as part of a recent migration to Asterisk -
Hylafax was very easily set up with a normal analog modem, which I
opted for initially as I (somehow) got the impression that faxing
wasn't all that straight forward with Asterisk/VoIP.  
Just today I've switched to using iaxmodem, which was equally easy. 
Anyone in the market for a plain 56K analog fax modem?

In my case, we have a dedicated fax number.
