Moving Phone Numbers Within Your Managed Domains

As a Reseller Admin, you can manage phone numbers (DIDs) within the domains assigned to you. This includes reassigning numbers between users, call groups, or services inside the same domain and releasing numbers back to inventory for reuse.

This article walks you through how to move numbers within your managed domains.

What You Can Do as a Reseller Admin

You can:

  • Move (reassign) numbers between users, call groups, or services within your managed domains.
  • Release unused numbers back to your domain inventory for later use.
  • Add numbers from your available inventory to users or services.

Step 1: Access Inventory

This is your Reseller or Top-Level Root Inventory, not the Inventory associated with the domain. 

  • Log in to the portal.
  • Ensure that you are in your portal root versus selecting the domain that currently has the number assigned.
  • Go to Inventory > Phone Numbers to see all numbers.

Step 2: Release a Number 

 

If a number needs to be freed up before assigning it to a new user or service:

  • Find the number in Inventory> Phone Numbers.
  • Click Edit next to the number.
  • Replace the current assignment (user, group, or service) with "Available Number".
  • Save the changes.


The number will now return to the domain inventory.

Step 3: Reassign the Number

To assign the number to a different domain, user, group, or service:

  • In Inventory > Phone Numbers, locate the number in your inventory.
  • Click Edit next to the number.
  • Enter the domain.
  • Choose the new assignment type (User, Call Group, Service).
  • Select the specific user or service.
  • Save changes.

Step 4: Verify and Test

Once reassigned:

  • Make a test call to confirm proper inbound routing.
  • Ensure outbound Caller ID is correct.
  • Update E911 records if the number is tied to an emergency address.

Best Practices

  • Document changes: Keep a record of number movements for billing and support.
  • Plan changes during off-peak times to minimize disruption.
  • Update related call flows: If the number was tied to auto attendants or ring groups, update those routes accordingly.
