Help - Can not get PBX to work with fxs /fxo card

Hello everyone
I am having trouble getting my fxs/fxo card to work, when I pick up the phone its just dead air but I can hear sounds if i push the button.

I confirmed that my sip trunk works with my Iphone but can someone please show me how to configure an extension to work with my analog phones?

No idea where to start :frowning:
