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.
