Example dial plan

This simplified example dial plan includes 5 dial plan rules that:

•Routes emergency calls (dialing 911) to the fxo1 PSTN interface

•Blocks international calls (the phone number begins with 011)

•Routes Toll Free calls (beginning with 18) to the fxo1 PSTN interface

•Routes non-international long distance calls (beginning with 1) to the fxo2 PSTN interface

•Routes all other external calls to the fxo3 and fxo3 PSTN interfaces

In this example, all outgoing calls are routed to the PSTN and not to other VoIP service providers.
