you need to configure pots and voip dialPeers for the incoming/outgoing legs of the calls.

pots dialPeers will be used for the FXO/FXS ports. voip dialPeers will be used for connection to ASTERISK voip pbx.

you need voice port configuration for your FXS to connect to your analogPhone.

you need voice port configuration for your FXO to connect to analog pstn. (if you have any)

see these links for more info:






there are plenty of examples throughout these for reference.
