Assign Voice Trunk
In DIDWW, assigning a trunk is a crucial step in configuring inbound call routing for Direct Inward Dialing (DID) numbers. A trunk acts as the bridge to the destination to which inbound calls from a DID are forwarded, leading to a PBX, SIP endpoint, or a PSTN number, depending on the trunk type.
Prerequisites
Before proceeding with the steps below, ensure that you have:
A DID Number. If you do not have one, refer to our guide on how to purchase numbers here: how to buy numbers here.
An Inbound Trunk. If you have not created any trunks yet, refer to the inbound trunk documentation here.
Assign The Trunk
The DIDWW user panel offers several ways to assign an inbound voice trunk, depending on whether you need to assign it to a single number or a batch of numbers.

Step 3: Select the Numbers
In this step, select the DID numbers for which you want to assign an inbound trunk using the checkmark column.
You can choose from the following selection options:
Manually select individual numbers by checking their respective boxes.
Use bulk selection options by clicking the checkmark to the left of the Country/City column:
Select All – Selects all DID numbers that match the current filter criteria, even if they span multiple pages.
Note
This option is available when you have more numbers than the per page limit (e.g., if you have 100 numbers and only 10 are displayed per page, all 100 will be selected).
Select Visible – Selects only the numbers currently displayed on the page.
Note
If the per page setting is 10, only those 10 numbers will be selected.
