To add a dial plan for dialing the PSTN and the main office

Dial plans are used to route calls made from an extension to an external phone system. The external phone system can be the PSTN or a VoIP provider. To route calls to an external phone system you add dial plan rules that include a dial pattern and list of outgoing destinations. When the FortiGate Voice unit receives a call from an extension and the number dialed matches a pattern in a dial plan rule, the FortiGate Voice unit routes the call to the outgoing destination added to the dial plan.
