As per me, you need fxo card as well at cme router to achieve both side calling. Actually, FXS generate the dial tone so connectivity should like below..

CME (FXS)------PBX (FXO)   (Call from PBX to CME)

CME (FXO)------PBX (FXS)   (Call from CME to PBX)

May someone else confirm it but I have done this kind of integration between Vega Gateways.
