About Practice Sessions
Practice sessions allow the host, presenter, and other panelists to practice an event before starting it. They're similar to a dress rehearsal—An event production team can perform all event functions without event attendees viewing the event.
If a teleconference has been started in the main event, when the host starts a practice session, the production team automatically enters a subconference, away from the main teleconference. Conversations in the subconference are private. Therefore, attendees outside the practice session cannot hear the practice.
Start a Practice Session
Before you end a practice session (select), close any shared documents, presentations, whiteboards, web content, and polls that you do not want to share with attendees. If you do not close them, attendees can view them once you end the practice session.
