Asterisknow 1.7.1 - FreePbx and ISDN problem

I’ve tried to install asterisknow 1.7.1 32-bit on a Pc with isdn card.
I configure isdn card using mISDN scan/config/module and misndportinfo show me that all is ok!
I configure trunks on Freepbx but doesn’t work on incoming/outogoing call.
I miss something as zapata.conf or similar?
There’s a guide “how to configure Freepbx with isdn card”?

Sorry for my english.
