    Hi @Maria Cottone

    Thank you for reaching out and for providing the details of your issue.

    Regarding external calls made from Teams Phone to regular phone numbers (PSTN), the number displayed to recipients is typically controlled by a Caller ID policy. According to Microsoft guidance, outbound caller ID behavior depends on the assigned caller ID policy, calling policy, and the PSTN provider. While Teams can display your assigned phone number, administrators also have the ability to replace it with another number or configure it to appear as anonymous.

    Therefore, I recommend contacting your IT administrator to review your current Caller ID configuration. Specifically, they can:

    • Navigate to Teams admin center
    • Go to Voice > Caller ID policies
    • Verify the policy assigned to your account (or the Global policy if no custom policy is applied)

    Under “Replace the caller ID with”, the setting should be configured as:

    • User’s number : this ensures that your assigned Teams phone number is displayed to recipients

    By selecting this option, your outbound calls should display your correct phone number, aligning with your requirement.

    For more details, please refer to: Manage caller ID for users - Microsoft Teams | Microsoft Learn

    Even when your Teams Caller ID is configured correctly, the final display may still depend on the recipient’s telecom carrier. In some cases, external carriers or mobile applications may classify calls as spam or unknown. While adjusting the Teams Caller ID policy can help improve identification, it does not guarantee that calls will not be flagged by external systems.

     

    I hope the information above helps clarify the possible causes. Please follow the suggested steps, particularly having your Teams administrator review the Caller ID policy, and let me know if this resolves the issue.

    If the problem persists, I would be happy to continue assisting you and explore further solutions.

    Thank you for your patience and for contributing to the forum.

    To show the phone number to the receiver in Teams, check both user-side and admin-side caller ID settings.

    1. Check if caller ID is being hidden in Teams (mobile with Teams Phone Mobile)
      • In the Teams mobile app:
        1. Tap profile picture.
        2. Tap Settings > Calling (under the Microsoft tab).
        3. Make sure Hide your phone number when dialing people who are outside Microsoft Teams is turned off.
      • If this is on, outbound calls will show as Anonymous to others.
    2. Ask the Teams/IT admin to review caller ID and spam settings
      • Admin should check the Caller ID policy and Calling policy assigned to the user:
        • If a Caller ID policy has Block incoming caller ID enabled, inbound PSTN calls to the user will show as Anonymous. This affects what the user sees, but similar policies or number formatting issues can affect how others see the user’s number.
        • Admin should also ensure the user’s phone number is configured in proper E.164 format (for example, +15551234567). Numbers not in E.164 format can increase the chance of being flagged as spam or not recognized correctly.
      • If Teams spam filtering is enabled, calls might be labeled “Spam likely”. Admins can adjust spam filtering as described in Configure spam filtering for calls in Microsoft Teams.
    3. If using Direct Routing
      • The admin/SBC operator should verify that the correct caller ID is sent in the SIP From header and that it matches the P-Asserted-Identity header, or adjust/remove P-Asserted-Identity as needed so the PSTN network presents the correct number.

    If these settings are corrected (hide caller ID off, number in E.164, SBC headers aligned), the called party should see the actual phone number instead of anonymous or likely spam.
