Mute participant
except lecturer
When the Mute Participants Except Lecturer option is enabled, the audio of all
participants in the conference except for the lecturer can be automatically muted
upon connection to the conference. This prevents other conference participants
from accidentally interrupting the lecture, or from a noisy participant affecting the
audio quality of the entire conference. Muted participants cannot unmute
themselves unless they are unmuted from the Collaboration Server Web
Client/RMX Manager.
You can enable or disable this option during the ongoing conference.
Notes:
When enabled, the mute indicator on the participant endpoints are not visible
because the mute participants was initiated by the MCU. Therefore, it is
recommended to inform the participants that their audio is muted by using the
Closed Caption or Message Overlay functions.
In the Collaboration Server Web Client/RMX Manager the mute by MCU
indicator is listed for each muted participant in the Audio column in the
Participants pane.
This option can be disabled during an ongoing conference, thereby unmuting all
the participants in the conference.
If the endpoint of the designated lecturer is muted when the lecturer connects to
the conference, the lecturer remains muted until the endpoint has been unmuted.
When you replace a lecturer, the MCU automatically mutes the previous lecturer
and unmutes the new lecturer.
When you disconnect a lecturer from the conference or the lecturer leaves the
conference, all participants remain muted but are able to view participants in
regular video layout until the you disable the Mute Participants Except Lecturer
option.
A participant can override the Mute Participants Except Lecturer option by
activating the Mute All Except Me option using the appropriate DTMF code,
provided the participant has authorization for this operation in the IVR Services.
The lecturer audio is muted and the participant audio is unmuted. You can
reactivate the Mute Participants Except Lecturer option after a participant has
previously activated the Mute All Except Me option. The participant is muted and
the lecturer, if designated, is unmuted.
In cascaded conferences, all participants (including the link participant) are
muted. Only the lecturer is not muted.
