I have a Cisco 1751 with VIC-2 FXO and VIC-2 FXS. How I can configure the the FXO port so that when I receive a call on the FXO port that it should be forwarded to FXS port.
When a voice call comes into the router, the router must match dial peers to route the call. For inbound calls from a POTS interface that are being sent over another POTS interface, the router matches a POTS dial peer for the inbound call leg and a POTS dial peer for the outbound call leg.
