. I want to check if the image sent by a speaker is meeting my expectations.

How to?

1. Check that your system (on witch you want to check) meet the speakers connections requirements
2. If it's not the case you could, for example, use an open network (guest Wifi, LTE, ...)
3. Dial-in to the virtual meeting room "No audio/video"
   
4. Once you are connected:
   • Switch the speaker to Spotlight mode (To make sure that this speaker will be the only one to be webcasted, and the other are muted)
   • Check the image from the speaker
   • It is possible that the speakers receive (before live) this type of image:
     
     This means that the assistant (you) does not send any image. Anyway this will not be webcasted as long as a speaker is connected.

Why icastGo doesn't display a video stream from the virtual meeting room for all dial-in methods?

The system considers that video sending and receiving is managed by the videoconference unit. So it is considered useless when a speaker dial-in through a videoconference unit or Skype for Business or Microsoft Teams meeting.
