Field/Option Description
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.
•The Mute Participants Except Lecturer 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
participants) are muted. Only the lecturer is not muted.
