How MS TEAMS Calls are Classified by Vyopta Tech Insights Analytics


The classification of a MS TEAMS call type by Vyopta depends on the information contained within the Call Detail Record (CDR) supplied by the TEAMS platform. Within the CDR, call types are classified by 'modality': the possible types are comprised as combinations of the following:

  • audio
  • video
  • videoBasedScreenSharing
  • screenSharing - no useful information is provided within the CDR for this modality

Vyopta will classify a call as one of:

  • Audio
  • Video
  • Unknown

This classification will be performed as follows:

  • Video - when the Video modality is present, or when VideoBasedScreenSharing is the only modality.
  • Audio - when the call has the Audio modality only, or the modalities are Audio and VideoBasedScreenSharing together, since this is an audio call with screen sharing
  • Unknown - when no audio or video modalities are present.
