Zap exten not dial tone fxs

Hi all,

I have a system asterisknow , and as this is with freepbx maybe I can get some help here.

I have a tdm400p analog card with 3 fxo and 1 fxs.

I want to connect and configure an analog phone to fxs port and make call to and from sip phones…

I add a zap extension but I can not get dial tone… should I configure a trunk before?

Here is some information:
