Hi Abdul


FXS cards are not meant to be connected with EPABX.. E&M cards are specifically meant to be connected with EPABX boxes.


I have seen FXS cards getting faulty by doing so and also seen working with few other EPABX models..

Hi Abdul


You may get reverse power from the EPABX and may damage your FXS port.


This is what we have heard even from CISCO but as i mentioned in my earlier post if you are sure about the EPABX port on which you are connecting the FXS port you can do that..
