19 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. 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 Allworx
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.
19.1 Create a DID Block
Click on the add 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.
19.2 Configure a Call Routing Plan for the DID Block
After the DID block is created, look at the Direct Inward Dial Blocks section on the Phone System / Outside
Lines page to see the routing plan associated with the block.
