Based on the docs in iaxmodem its better to have iaxmodem on your
asterisk server and hylafax (if needed) on a remote server.  The lag
issues between iaxmodem and asterisk are more critical than hylafax and
iaxmodem.

IAXModem works like an iax client, if you redirect calls to that
extension they goto iaxmodem if you dont they are handled elsewhere.
Treat that as just another extension for all intents and purposes.
Problems however may arise if asterisk is told to redirect all calls
with a fax tone to rxfax, so you have to deal with that in your
dialplan.  

You would have to either get clever with the extension or do did based
routing ...

exten => fax,1,gotoif(something?2:3)
exten => fax,2,rxfax(somefile)
exten => fax,3,Dial(IAX2/iaxmodemExt,60,R)


Although this isnt an issue if you do did based routing and the given
did is one or the other for that context but not both.

Hope this helps (and I hope I am right, but I have been reading a lot
and think I am, I am sure lee will point out anything I got wrong)
