DRAG DROP
-

Your company has a main office in New York and a branch office in Calgary. All offices connect to each other by using a dedicated WAN.

You have a Microsoft Teams Phone deployment.

You need to recommend a Direct Routing solution that meets the following requirements:

• If a Session Border Controller (SBC) fails in the New York office. PSTN services must remain available through a local PSTN egress in New York.
• The Calgary office must prioritize a local PSTN egress and ensure that PSTN services remain available in the event of a local SBC outage.
• The number of SBCs must be minimized.

What should you recommend for each office? To answer, drag the appropriate components to the correct offices. Each component may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

NOTE: Each correct selection is worth one point.

New York: 2 SBCs with local PSTN egress and HA configuration. Calgary: 1 SBC with local PSTN egress and failover to New York's SBCs in case of failure. Minimizing SBCs: By deploying 2 SBCs in New York (with HA) and 1 SBC in Calgary, you minimize the number of SBCs while ensuring local PSTN availability and failover capabilities. High Availability: Ensures that if any SBC fails, there is always a backup in place, either locally (New York) or via the WAN (Calgary).

A single SBC in Calgary with two voice routes (VR1 and VR2). VR1 first priority to route calls to local SBC, VR2 lower priority to route calls to New York SBC.
