Example FortiGate Voice branch office configuration

Configuring the FortiGate Voice PSTN and PBX settings

In addition to PSTN and head office support the dial plan must also support Emergency, international, toll free and long distance dialing.

Use the following steps to add a dial plan with the following dial plan rules:

Allows the branch office to call the PSTN

Dialing 911 for emergencies

Dialing 9 followed by a country code for international calls

Dialing 9 followed by 18 for toll free calls

Dialing 9 followed by 1 for long distance calls

Dialing 9 for all other PSTN calls

Allows the branch office to dial head office extensions directly. The dial plan rule sends calls starting with 2 to the VoIP provider where they are routed to the head office. This dial plan does not include any other settings because users dial the head office extension number directly without a prefix.
