Telephone Number Services (TNS) - Service Desk
There is a new process to interact with the Telephone Number Services (TNS) service desk. You can now open tickets, view tickets, and track communication in a single place that is integrated with the Teams Admin Center. This article describes everything you need to know to contact the service desk.
As of July 22, 2021, the current email system has been retired.
To contact the service desk:
Log in to your Teams Admin Center - admin.teams.microsoft.com.
In the left-hand pane, select Phone numbers.
At the top of the page, select Get phone number support. You will see the Phone Number Service Center.
Only someone from the same tenant will be allowed to create a case. That is, someone from @fabrikam.com cannot create a case on behalf of @contoso.com.
From the Phone Number Service Center, you can create new cases, view existing cases, communicate with the service desk, and manage your user profile. These tasks are described in more detail in the following sections.

Case type can be one of the following:
Custom Calling Name (US Only) - Set a custom calling name on your Microsoft phone numbers. This is applicable to United States phone numbers only.
