How to Manage Phone Number Visibility in Microsoft Teams

Administrative Control: Caller ID Policies

How to configure Caller ID Policies (Admin Only)

Admins manage Microsoft Teams phone number visibility for everyone in the company using Caller ID policies. These policies, set up in the Teams Admin Center, control how each person’s phone number appears when they make a call.

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 use PowerShell to quickly set Microsoft Teams phone number visibility for many people at the same time. This tool lets you run commands to automatically set specific caller IDs for users, saving time compared to changing each one individually.

# 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 as expected, there are a few common reasons. Settings might still be updating, user privacy options could be enabled, or the necessary licenses might not be assigned to the account.

• 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)
