Configuring direct inward dialing
You can configure direct inward dialing (DID) for calls. DID allows the FortiGate Voice unit
to direct calls from external callers directly to PBX extensions. For example, you could set
up DID so that external users call 555-1234 and DID directs the call to extension 1234.
Using the FortiGate Voice unit direct inward dial settings you associate an incoming PSTN
interface (if supported by your FortiGate Voice unit) or VoIP service provider with a PBX
extension. When an incoming call is received from one of these sources, if the last digits of
the dialed number match the selected extension number the FortiGate Voice unit directs
the call directly to the extension. For this to work you must obtain an external phone
number with the last digits matching the selected extension.
To configure direct inward dialing, go to PBX > Calling Rules > Direct Inward Dial, enter
the information, and then select OK.

From the CLI you can use the cid-number option of the config pbx did command to
specify the number called from an external line that is re-directed to the selected
extension. Use this option if the extension number cannot be matched with the external
number. In the following example, DID sends calls received on the fxo1 PSTN interface
that end with 5555 to extension 1234.
