In some cases, True can also be represented as 1 and False can be represented as 0. Dimension data types and units Booleanīoolean values are always either True or False. Many Dimension values can also be used as filters. Dimensionsĭimensions information is based in part on data uploaded to the CQD portal.

The First Is Caller dimension can be used to help identify which endpoint was the caller or callee. That First and Second classification is separate from which endpoint is the caller or callee. second is set based on internal ordering of the user agent category to ensure that the ordering is consistent.įor example, here each row represents a pair of User Agents involved in a stream: User Agent Category of Caller

If both endpoints are the same type, first vs.

A Client endpoint is considered Second unless the stream is between two Server endpoints.

A Server endpoint (AV MCU, Mediation Server, and so on) is considered First when a Server is involved in the stream or call.

The following logic determines which endpoint involved in the stream or call is labeled as first:

Many of the dimensions and measurements in CQD are labeled as first or second. To learn more about CQD, see Use CQD to manage call and meeting quality in Microsoft Teams. This topic provides detailed information about the dimensions and measurements visible through CQD. The Call Quality Dashboard (CQD) for Microsoft Teams and Skype for Business Online allows you to better understand call quality of calls made with these services.
