How to connect Analog Phone to FreePBX?


I am trying to connect some simple analog phone to my asterisk

i am going to freepbx admin -> applications -> Extensions -> generic dhadi extention
in user extention i type 150 for instance and in channel i select 2 (port 2 on the card)

anyway, when i try to call 150 from IP phone i see some reaction on the anaglog phone but when i answer nothing happans.
when i try call my ip phone from the analog phone nothing happans too.
