hello:
As you said, channels 1 is FXS module (green module), channels 3 and 4 are FXO module(red module). Because the FXS module use the FXO signalling, and the FXO module use the FXS signalling. So the result is right.

Hi:
If your card has modules FXO, FXO, FXS, FXS (in that order), put:
fxsks=1-2
fxoks=3-4
If your card has modules FXS, FXO, FXO, FXS (in that order), put:
fxoks=1,4
fxsks=2-3
If your card has modules FXS, (empty), FXO, FXS (in that order), put:
fxoks=1,4
fxsks=3
NOTE: the names are reversed. For FXO modules you use fxsks= and for FXS modules you use fxoks=
