It is quite common for a Zoom user to schedule a Zoom meeting, include a Zoom Room, and attend the meeting from the Zoom Room itself. Depending on meeting configuration settings, the meeting host may need to start the meeting from their desktop or mobile client before the Zoom Room and other users can join, or may need to enter their host key on the Zoom Room Controller. To streamline this process, an administrator can configure the Zoom Rooms of their account to automatically join Zoom meetings hosted by users on their account. If this feature is enabled and the Zoom Room joins before the host or other meeting participants, the Zoom Room will automatically become the meeting host and start the meeting. The actual meeting host can always reclaim host privileges after joining the meeting.
