How to Manage Phone Number Visibility in Microsoft Teams

Administrative Control: Caller ID Policies

For IT administrators, managing Teams caller ID policy settings is a core task. You can control how numbers are presented to external parties using the Teams Admin Center. This is often used to mask individual user numbers with a main company line.

How to configure Caller ID Policies (Admin Only)

Microsoft Teams phone number visibility for your whole company is managed by admins using Caller ID policies in the Teams Admin Center, which decides how everyone’s number shows up.

1. Log in to the Teams Admin Center.
2. Navigate to Voice > Caller ID policies.
3. Select an existing policy or create a new one.
4. Toggle Mask caller ID to hide the user’s specific number and show a service number instead.
5. Assign the policy to specific users via the Users tab.

PowerShell Automation for Teams

Admins can quickly change Microsoft Teams phone number visibility for lots of people at once using PowerShell, a tool that lets you run commands to set specific caller IDs automatically.

# Example: Set a specific number as the caller ID for a user
Set-CsCallingLineIdentity -Identity "user@domain.com" -CallingLineId "+15550100123" -EnableUserOverride $false

Refer to the official Microsoft documentation for more details on these cmdlets.

Troubleshooting Phone Number Visibility

If your Microsoft Teams phone number visibility isn’t showing correctly, it’s often because settings take time to update, privacy options are on, or the right licenses aren’t assigned.

• Policy Latency: Changes made in the Teams Admin Center or via PowerShell can take up to 24 hours to propagate.
• User Privacy Settings: Ensure the end-user has not manually disabled their contact information visibility in the Teams desktop client.
• License Requirements: Ensure the user is assigned the correct Audio Conferencing or Phone System license.

Steps to show or hide your phone number (End-User)

You can easily change how your Microsoft Teams phone number visibility appears to others right inside the Teams app, without needing help from an admin.

1. Open the ⊞ Start menu and find Microsoft Teams in your apps list.
3. You can also open it from the Taskbar.

4. 

5. If the small window opens, click the expansion button to open the full Teams window.

6. 

7. Click the Settings and more (…) button near your profile picture and select Settings.

8. 

9. Click the Privacy tab on the left side of the window.

10. 

11. Select the button labeled Manage contact information.
