Question #17
Your company has offices in Paris and London.
You are migrating from an on-premises PBX telephony solution to a Microsoft Teams Phone deployment that uses Direct Routing. You plan to use the existing telephony carrier. The new solution will provide telephony services to users in Doth offices.
You need to recommend a solution that is the most resistant to possible failures. The solution must ensure that calls are routed through each user's respective office.
Which two actions should you include in the recommendation? Each correct answer presents part of the solution.

- AConfigure voice routing policies for each office.
- BConfigure a single voice routing policy for all users.
- CDeploy a highly available Session Border Controller (SBC) pair to each office.
- DDeploy one Session Border Controller (SBC) to each office. Configure the SBCs as a high-availability pair.
Correct Answer:
AC
AC
GPT-4o - Answer
To ensure high reliability in a Microsoft Teams Phone deployment using Direct Routing, configuring voice routing policies for each office and deploying a highly available Session Border Controller (SBC) pair in each location are critical recommendations. Each office having its own routing policies enhances efficiency by enabling local call routing, reducing latency, and potentially reducing costs. Additionally, deploying a highly available SBC pair in each office secures the infrastructure against hardware failures, network issues, and other disruptions, maintaining continuous telephony service for all users. This approach maximizes uptime and resilience for the telephony system.

Question #19
You have a Teams Phone deployment. The deployment has a single Session Border Controller (SBC) that uses Direct Routing.
Users report that outbound PSTN calls fail.
You need to identify the quantity of specific SBC SIP errors.
What should you review?
Users report that outbound PSTN calls fail.
You need to identify the quantity of specific SBC SIP errors.
What should you review?
- AQuality of Experience Reports in Microsoft Call Quality Dashboard
- Bthe Jitter tab in Network parameters in the Microsoft Teams admin center
- Cthe network effectiveness ratio on the Usage tab for the SBC in the Microsoft Teams admin center
- DEndpoint Reports in Microsoft Call Quality Dashboard
Correct Answer:
A
A
GPT-4o - Answer
Reviewing the Quality of Experience Reports in the Microsoft Call Quality Dashboard provides a broad overview of call quality trends, but it may not give the detailed breakdown of SBC SIP errors needed to troubleshoot specific issues with outbound PSTN calls. For a more detailed analysis, Endpoint Reports in the Microsoft Call Quality Dashboard are preferable as they offer insights into individual calls and can pinpoint SIP errors at the SBC level, which are likely causing the call failures. While the Quality of Experience Reports do offer valuable data, they might not be as useful for this specific troubleshooting need.
Question #20
You have a Microsoft Teams Phone deployment.
You need to implement PSTN connectivity by using Direct Routing.
What are three requirements for the implementation? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

- Aa public DNS entry that maps the FQDN of the Session Border Controller (SBC) to a public IP address
- Ba Session Border Controller (SBC) that uses a hostname in the onmicrosoft.com domain
- Ca Teams-certified Session Border Controller (SBC)
- Da firewall rule that opens a TCP signaling port to Microsoft Teams
- Ea firewall rule that opens a UDP signaling port to Microsoft Teams
Correct Answer:
ACD
ACD
GPT-4o - Answer
Absolutely, for setting up Direct Routing in Microsoft Teams, three components are vital: a public DNS mapping for the Session Border Controller (SBC), a certified SBC, and specific firewall configurations. Importantly, the firewall must allow TCP signaling, specifically through port 5061, which is fundamental for SIP (Session Initiation Protocol) connections to Teams. Ensure these elements are well-configured to enable effective communication between your on-premises network and Microsoft Teams over the Public Switched Telephone Network (PSTN).
