Seeking Assistance with MS Teams Call Quality Analysis-Issue with Unclassified Stream Classification

[Kalavathi]

Hi everyone,

I'm retrieving the call quality data for MS Teams using dimensions and measures for analysis. However, I've noticed that the majority of streams are classified as "Unclassified" instead of "Good" or "Poor". Could someone please help me understand the reason behind this?

Thank you.

Hi @Kalavathi ,

Streams in the Call Quality Dashboard (CQD) for Microsoft Teams are classified as Good, Poor, or Unclassified based on the values of the available key quality metrics. It may be due to an issue with the data processing or visualization if there is only the streams which are classified in CQD as Unclassified. To determine the cause, you may need to review the data source, the queries used to filter and transform the data, and the Power BI report settings.

Good, poor, and unclassified calls

---

• Good or poor: A good or poor call consists of a call that contains a complete set of service metrics, for which a full QoE report was generated and received by the service. Determining whether a stream is good or poor is described earlier in this article.

• Unclassified: An unclassified stream doesn't contain a full set of service metrics. These can be short calls—usually less than 60 seconds—where averages couldn't be computed and a QoE report wasn't generated. The most common reason for calls to be unclassified is that there was little to no packet utilization. An example of this would be a participant who joins a meeting on mute and never speaks. The participant is receiving, but not transmitting, media. Without media being transmitted, there won't be any metrics available for CQD to use to classify the endpoint's outbound media stream.
