• The first rule requires branch office phones dial 9 to connect to phone numbers on the
PSTN. This dial plan must also strip the first digit (the 9) from the dialed number.
• The second rule allows branch office phones to dial head office extensions directly.
The dial plan rule sends calls starting with 1 to the VoIP provider where they are routed
to the head office. This dial plan does not strip any digits because users dial the head
office extension number directly without a prefix.

To add the extensions that are on the branch office internal network
Use the following steps to add extensions to the FortiGate Voice unit for the IP phones that
are to be connected to the internal network. You add identifying information to each
extension entry. The IP phone must be configured with identifying information that
matches an entry in the extension list in order to get an extension from the FortiGate Voice
unit. Extension numbers are independent of the IP address of the IP phone.
