15 Direct Inward Dialing (DID)

Direct inward dialing (DID) is a service offered by a local telephone company that provides a block of phone

numbers for calling into a PBX without requiring a physical line for each number. In cooperation with the PBX,

each number is mapped to a PBX extension so that each PBX user has a unique outside number that can be

used to ring the user’s phone directly rather than directing the incoming call to an auto attendant.

Configuring the Bizfon server for DID service involves 3 steps:

1. Creating a DID block.

2. Configure the call routing plan for the DID block.

3. Create a DID line for each DID trunk line plugged into the server.

15.1 Create a DID Block

Click on the New DID Block link on the Direct Inward Dial Blocks section of the Phone / Outside Lines

page.

Enter the Starting Phone Number and Total number of phone numbers in the DID Block as specified by

the telephone company. Unless you already have an existing DID Routing Plan that you want use, leave it as

the default to make a new routing plan. As it says, this creates a new routing plan for use by this DID block.
