Collaboration Communications Systems Engineer — Question 8

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?

Answer options

• A. Quality of Experience Reports in Microsoft Call Quality Dashboard
• B. the Jitter tab in Network parameters in the Microsoft Teams admin center
• C. the network effectiveness ratio on the Usage tab for the SBC in the Microsoft Teams admin center
• D. Endpoint Reports in Microsoft Call Quality Dashboard

Correct answer: C

Explanation

The correct answer is C because the network effectiveness ratio on the Usage tab provides insights into the performance of the SBC including SIP errors. Options A and D focus on call quality but not specifically on SBC errors, while option B relates to network jitter, which does not directly address the identification of SIP errors.
