Fortinet FortiGate Voice 4.0 MR1 사용자 설명서

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.
