Voice routing policies in Microsoft Teams

This article talks about Voice routing policies in Microsoft Teams

Voice routing policies

Voice routing policies in Microsoft Teams act as containerized permissions that determine which PSTN (Public Switched Telephone Network) usage records apply to a user, regulating how they make and receive external phone calls via Direct Routing.

These policies allow administrators to define which Session Border Controllers (SBCs) or voice routes, such as local, national, or international, are accessible to specific users

Lets create Voice routing policies step by step

Open Teams admin center –> https://admin.teams.microsoft.com/

Navigate to TAC–> Voice –> Voice routing policies

You can use the Global (Org-wide default) policy, or create one or more custom mobility policies for people in your organization

Lets add one test policy

give a suitable title

add PSTN usages to voice routing policies, which are assigned to users, and voice routes. PSTN usages are evaluated in the order they’re listed until a match is found.

finally save it

finally assign it to the set of users
