Hi,
I have a S20 PBX with O2 module. Line is ok, but how can I use my Voip Phone, Cisco SPA303 with the FXO Lines? Is it possible?
Thank you.

Thank you.
It is possible for the IP phone register to the PBX and make outgoing calls through the S20's FXO lines(PSTN line from the Telecom connected to the FXO port).
