As a customer administrator, you can delete phone numbers from an organization, in bulk, in Control Hub.
Before you begin
Only phone numbers that are unassigned can be bulk deleted.
If a number belongs to a block of numbers, it can’t be deleted unless all numbers in that block are unassigned.
From the customer view in https://admin.webex.com, go to .
Select the phone numbers you’d like to delete.
Click Delete from the top navigation menu.
Confirm your deletion.
The bulk delete process starts and can be viewed in Task Manager.
