Meta Description: Learn how to block incoming external PSTN calls on Microsoft Teams for a specific user without affecting the entire tenant. Step-by-step guide, tips, and best practices.
Introduction
Microsoft Teams is a powerful tool for communication and collaboration, but sometimes businesses need to restrict external calls for specific users. For example, you may want to block incoming PSTN (Public Switched Telephone Network) calls for a particular employee without affecting the entire organization.
In this blog, we’ll walk you through how to block incoming external PSTN calls on Microsoft Teams for a specific user—not tenant-wide. We’ll also explore why this feature is useful, how it works, and best practices for managing call restrictions in Teams.
Why Block Incoming External PSTN Calls for a Specific User?
There are several scenarios where blocking external calls for a specific user makes sense:
- Employee Role Changes: An employee may no longer need to receive external calls due to a role change.
- Security Concerns: Restricting external calls can prevent unauthorized communication.
- Focus and Productivity: Blocking external calls can help employees focus on internal collaboration.
- Cost Management: Reducing unnecessary external calls can lower telecommunication costs.
How to Block Incoming External PSTN Calls for a Specific User
Blocking incoming external PSTN calls for a specific user in Microsoft Teams involves configuring Calling Policies and Voice Routing Policies. Here’s a step-by-step guide:
Step 1: Access the Microsoft Teams Admin Center
1. Log in to the Microsoft Teams Admin Center.
2. Navigate to Voice > Calling Policies.
Step 2: Create a New Calling Policy
1. Click Add to create a new calling policy.
2. Name the policy (e.g., “Block External Calls”).
3. Under Inbound calls, set the option to None to block all incoming external PSTN calls.
4. Save the policy.
Step 3: Assign the Policy to the Specific User
1. Go to Users > Manage Users.
2. Select the user you want to block external calls for.
3. Under Policies, assign the newly created calling policy (e.g., “Block External Calls”).
Step 4: Verify the Configuration
1. Test the setup by having someone call the user’s external phone number.
2. Confirm that the call is blocked or redirected as intended.
Alternative Method: Use Voice Routing Policies
If you want more granular control, you can use Voice Routing Policies to block external calls for specific users. Here’s how:
- Go to Voice > Voice Routing Policies in the Teams Admin Center.
- Create a new policy and configure it to block calls from specific PSTN routes.
- Assign the policy to the user.
This method is ideal for organizations with complex call routing requirements.
Best Practices for Managing Call Restrictions in Microsoft Teams
- Use Groups for Policy Assignment: Assign policies to groups instead of individual users for easier management.
- Regularly Review Policies: Periodically review and update calling policies to ensure they align with business needs.
- Communicate Changes: Inform users about any changes to their calling permissions to avoid confusion.
- Monitor Call Logs: Use Microsoft Teams call logs to monitor and analyze call activity.
