As described above, a user privilege level confers a certain level of control over a conference, with that level of
control possibly depending on whether that user is the conference owner or not. These conference control levels
have the following meaning:
This level of control permits the following operations:
With full conference control, a user is able to disconnect participants, connect

A user with full conference control can view and modify any aspect of the
conference's configuration. This includes the start time, end time, or repetition

text message to all connected participants' video displays and change the
Conference custom layout.
Additionally, full control includes all of the operations covered by limited control,

Thumbnail previews are shown by default, but you can configure the user
interface not to show them. The setting that controls this is the Show video
thumbnail images option on the page. Note that the MCU
will not show thumbnail previews on the participant list page if encryption is

conferences where encryption is optional and there are encrypted participants.
Via the participant list, it is also possible to mute (or stop muting) individual
endpoints' audio, change the conference's "important" participant, and enable or
disable the participants' ability to affect their own layouts via Far-End Camera
Control or DTMF tones.
This includes being able to choose what view layout (or family) is used for
constructing the conference view being sent to a participant, changing the
