Muting Conference Participants
Only presenters can mute and unmute conference participants.
If a presenter mutes your audio, a notification is displayed on your device, and a Mute icon   is 
displayed next to each person who is muted. When a presenter mutes your audio in the Skype for 
Business client, it takes one second for the mute icon to display on your device.
You must wait for the presenter to unmute your audio before you can speak in the conference again.
