Question
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?
- 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 Correct
- D. Endpoint Reports in Microsoft Call Quality Dashboard
Explanation
The Direct Routing health dashboard in the Teams admin center shows the network effectiveness ratio for each SBC, which is lowered by SIP failure responses from the SBC (for example 504 Server Time-out), and lets you see the calls and failures behind it. Jitter measures media quality, not call setup failures. Call Quality Dashboard Quality of Experience and endpoint reports focus on media quality and devices rather than SBC SIP error counts.
