Asterisk (trixbox) with hylafax

I have a Asterisk ( trixbox 2.2.3 ) configured with phones, and hylafax. I have 2 billion cards (hfc with bristuff and flor patch) installed. I can't figure out why iaxmodem is not communicating with hylafax. I also installed spandsp but i had all the faxes croped, and out of normal page. I need someone to help me to configure a solution that send faxes to email, i prefer hylafax. I need this soon as possible, everything is installed, just a small correction for a guru.
