Call redirection

Hi, i’m beginner in freepbx,
I have good knowledge about shell and linux configuration,
I have to do an simple call redirection, the call received in 1 fxo port,
have to be redirect in external call number by the second fxo port.
so, i installed freepbx, with an digium card 2 fxo port,
freepbx work fine, and hardware is detected.
Can i ask you where begin for juste make this simple redirection?
thanks a lot

I didn’t made an confusion between fxo and fxs,
because, the call receive, come from an external line.
and the redirection is send to other external line.
