Once logged in an easymeeting™ meeting, simply press the booking button on the toolbar (or use the horizontal User menu à Raise hand) to send a request to speak to the supervisor of the meeting.

When the supervisor (who functions as mediator) has the opportunity will enable the user on the Full-Duplex channel.
The order of reservations is displayed as a number, in increasing order of requested reservation, next to the name in the user window.
