How many callLegs are created when I use chat, audio/video and send/receive a presentation?


A callLeg is an element of a meeting in a space that you can access via the Meeting Server API.

The number of callLegs created for one participant depends on what device you are using to attend the meeting:

  • A participant on a Cisco Meeting App can use any combination of chat, video, audio and show/receive a presentation. These elements comprise one callLeg, and count as one participant. 
    Connecting/pairing an endpoint to a Cisco Meeting App does not change the callLeg count or the participant count (for example as reported in a CDR)
  • A participant on web app can use video, audio and show/recieve presentation. These elements comprise one callLeg, and count as one participant.
  • A participant in a meeting on a SIP endpoint can use video, audio and send a presentation. These elements comprise one callLeg, and count as one participant
  • A participant on a Lync client can use any combination of chat, video, audio and send a presentation. Any combination of these elements counts as one participant but each element is a separate callLeg. (Received presentations are displayed in the main video stream.)

Note: Cisco Meeting App for WebRTC (thin client) is removed in Cisco Meeting Server version 3.0. You can use Cisco Meeting Server web app instead of Cisco Meeting App for WebRTC.Cisco Meeting App for desktop, iOS and WebRTC are no longer supported from version 3.0.
