The Audio Muted Participant box lists all the participants currently 
connected to the conference. A clear check box indicates that the 
participant's audio channel is in the normal mode (unmuted), while a 
checked box indicates that the participant's audio channel is muted.

Select the check boxes of the participants to be muted.
Alternatively, to mute all the participants except those who are video 
forced (that is, those who are displayed in one of the video layout 
windows) click the Select Unforced Participants button. All the 
participants that are not video forced are checked. You can now unmute 
and mute an individual participant in the Audio Muted Participants box.

Click OK.

The participants’ audio icon 

 

in the Audio column in the Monitor 

and Status panes now

 

indicates that the audio channel was muted by the 

operator. 

The operator or chairperson can lock or unlock an On Going Conference to 
dial-in participants. In addition, you can lock a conference during setup 
(whether you are defining a new conference in the Reservation template or in 
the Conference Properties dialog box) and, if required, unlock it while it is 
ongoing. The purpose of conference locking is to:

•

Limit the number of dial-in participants connecting to the conference

•

Prevent additional participants from connecting to the conference once 
all the required participants are connected

•

Save resources

You can lock and unlock the conference from the right-click menu, from the 
toolbar or from the Conference - Properties dialog box.

Alternatively, the chairpersons can lock or unlock a conference from their 
endpoint using the appropriate DTMF code (the default code to lock a 
conference is *7, and the default code to unlock a conference is #7).

Expand the On Going Conferences list.
