Radius install problems

Hi guys,

I am new with asterisk so please be patient with me:)

OK, I have installed asterisk, made a few calls. Everything works perfectly. My next step was to install and configure radius client for authentication with freeradius on different server. I have installed radiusclient-ng client just it says here: https://wiki.asterisk.org/wiki/display/AST/RADIUS+CDR+Backend

Must I unable radius client authentication or after install this should automatically work? Because If I make call nothing happens.

Plase help!
