Implement and configure Teams Phone

Question

You have a Teams Phone deployment that has users in Canada and the United States. You have a Session Border Controller (SBC) in Calgary and an SBC in New York City. Both SBCs are connected to Direct Routing. You plan to implement toll bypass for the users in Canada. The solution must meet the following requirements: - Prioritize the New York City SBC for calls to numbers in the United States. - Leverage the Calgary SBC for resiliency if the New York City SBC is unavailable. You create a PSTN usage named Canada and associate this policy to a voice routing policy. Which two voice routes should you create with the Canada PSTN usage? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

Explanation

The Canada PSTN usage must contain two voice routes to satisfy both requirements. First, create a route matching only US number patterns with priority 1 pointing to the New York City SBC (D) - this ensures US-bound calls prefer NYC. Second, create a wildcard route (matches all numbers) with priority 2 pointing to the Calgary SBC (A). This wildcard route handles Canadian PSTN calls via toll bypass through Calgary, and also serves as the resiliency fallback for US calls if NYC becomes unavailable. Teams evaluates routes in priority order, so NYC wins for US numbers when available, and Calgary catches everything else including Canadian local calls.
