Is it possible to route calls between two PBXs using FXO modules if the PBXs do not support E&M?

No. One side would have to be FXS. FXO to FXO is not physically possible.

Is PBX routing possible with E&M ?

Yes, analog E&M can support back-to-back connections.

hi Markus Schneider. How am I going to connect the two PBXs if I going use FXO to FXS?
