As of ~ 2015, CLOUD X-10 has a "LECTURE MODE"
Account managers can select a layout in which a selected participant or system shows full screen. Participants only see the lecturer participant; the lecturer sees all participants.
To access, click on any existing meeting from the CLOUD Desktop Application (ver 9.0.111 or higher).
Assuming you OWN the meeting, you should see an edit button.
You should see a 'lecturer' dropdown menu near the bottom.
You can also do this when you create a new meeting.
If you encounter situations where users are complaining about not being able to see anyone else besides a SINGLE party... chances are the virtual conference room is in LECTURE MODE**
