Is it possible to add the GSM MODULE on this PBX model already with equiped with the FXS module ?

Actually the fxs, GSM, fxo and etc are modules which needs to be installed to enable those functions associated with these features work. Unless it's the hybrid type which production has being stopped by "Yeastar".
