strange, you say they are FXO modules (and you only have 3), and they 
don't work (1:10), and that when you use a phone (which is as fxs 
device) it works great in port 4, well ....

are you sure they are FXO modules and not FXS?  if you only have 4 
modules, why would you be pluggin into port 4 when the 3 moules should 
be installed in order. (ports 1,2,3)

so, either you aren't telling us everything, or you were confused and 
bought FXS modules when you wanted FXO modules, which is it?
