Teams Calling Directory with Assigned MS Numbers

Teams does not provide a separate “Teams Calling directory” that shows only users with Teams Phone numbers, nor does it require a phone number for a user to appear in search.

Key points based on current behavior:

1. Directory search vs. phone numbers
   • Teams user search is based on the organization’s directory (Azure AD/Exchange address book), not on whether a user has a Teams Phone number.
   • As documented for Auto attendants and Call queues, Teams users can be found and called without having a phone number or Calling Plan assigned. Phone number assignment is not a prerequisite for being discoverable:
     • “Teams users who can be reached by using Dial by Name or Dial by Extension aren't required to have a phone number or have Calling Plans assigned to them.”
   • This same directory underlies user search in Teams; it does not filter or label users by whether they have a Teams Phone number.
2. Where Teams Phone numbers are visible (admin-only)
   • Teams Phone numbers assigned to users are visible centrally only in the Teams admin center, not in an end-user-facing directory:
     1. Go to Microsoft Teams admin center.
     2. Navigate to Voice > Phone numbers.
     3. Use the Assignment Status column and filters (Assigned to user, Unassigned, etc.) to see which numbers are assigned and to whom.
   • This view is for admins; end users do not see this as a “phone directory” inside the Teams client.
3. Differentiating users with/without Teams Phone numbers
   • In the Teams client, there is no built-in visual indicator in the people search results that a user has a PSTN phone number assigned via Teams Phone.
   • Because directory search is identity-based (user account) rather than phone-number-based, searching by name will show colleagues from the org directory regardless of whether they have a Teams Phone number.
4. Calling behavior to mobile devices
   • If a person does not use the Teams app, calling their Teams identity will still attempt a Teams call (which they may not answer if they never sign in).
   • If the goal is to call a cell phone number directly via PSTN, that requires:
     • A Teams Phone–enabled account (appropriate license and calling capability), and
     • Dialing the phone number from the Teams dial pad, not relying on the directory to distinguish who has a Teams-assigned number.
5. Options for working with contacts
   • For personal contact management, the People app in Teams lets users create and manage contacts, including phone numbers, but this is per-user and not a tenant-wide phone directory:
     • Users can add contacts by name or phone number and store additional details.
     • These contacts sync with Outlook but do not expose a global “Teams Phone directory” of all assigned numbers.

In summary:

• There is no separate end-user Teams directory that lists only Teams Phone–enabled users or exposes their Teams-assigned PSTN numbers.
• Admins can see and filter all assigned phone numbers in Teams admin center → Voice → Phone numbers.
• User search in Teams is directory-based and does not distinguish or label users by Teams Phone number assignment.
