MS-721: What Should You Configure First to Link Voice Routing Policy to Voice Route in Microsoft Teams Direct Routing?

Learn the crucial first step in linking a voice routing policy to a voice route in Microsoft Teams Direct Routing. Discover why configuring PSTN usage records is essential for seamless call routing.

Question

You have a Microsoft Teams Phone deployment.

You use Direct Routing with a Session Border Controller (SBC) named SBC1.

You need to link a voice routing policy to a voice route named Route1.

What should you configure first?

Select only one answer.

A. a network roaming policy
B. a network site
C. emergency addresses
D. PSTN usage records

Answer

To link a voice routing policy to a voice route in a Microsoft Teams Direct Routing deployment, the first step is to configure Public Switched Telephone Network (PSTN) usage records. These records act as the bridge between voice routes and voice routing policies, ensuring that calls are routed correctly through your Session Border Controller (SBC) and telephony infrastructure.

D. PSTN usage records

Explanation

A call routing policy (also called a voice routing policy) is a container for PSTN usage records. You create and manage voice routing policies by using Voice > Voice routing policies in the Microsoft Teams admin center or by using Windows PowerShell. Before you create a voice routing policy, you must configure the PSTN usage records, which can then link the policy to Direct Routing voice routes.

Why PSTN Usage Records Are the First Step

PSTN usage records are essential because they define the permissions and routing logic for calls. They are used to:

• Authorize Call Routing: PSTN usage records specify which routes users are allowed to use based on their assigned voice routing policy.
• Link Components: They connect voice routes (which define how calls are routed) with voice routing policies (which determine user permissions).
• Enable Flexibility: By associating PSTN usage records with multiple routes and policies, administrators can create tailored call-routing configurations for different user groups or locations.

Without PSTN usage records, you cannot associate a voice route with a voice routing policy, making them the foundational element of call routing in Direct Routing setups.

Configuration Steps

Create PSTN Usage Records:

1. Navigate to Voice > Direct Routing in the Microsoft Teams Admin Center.
2. Select Manage PSTN usage records and add new records as needed (e.g., “US and Canada”).
3. Save your changes.

Create Voice Routes:

1. In the same section, go to Voice Routes and define your route settings, such as dial patterns and SBCs.
2. Associate the relevant PSTN usage record(s) with the route.

Create Voice Routing Policies:

1. Navigate to Voice > Voice Routing Policies.
2. Add a new policy and associate it with the appropriate PSTN usage record(s).
3. Save and assign the policy to users.

Supporting Evidence

• PSTN usage records are explicitly required to link voice routes with routing policies, as outlined in Microsoft’s documentation on Direct Routing configuration.
• They ensure that users can only access routes authorized by their assigned policies, making them integral to security and functionality.

By starting with PSTN usage records, you lay the groundwork for effective call routing in Microsoft Teams Direct Routing. This step ensures that all subsequent configurations—voice routes and policies—function seamlessly.
