Mute and Unmute Others

Mute and unmute audio, either by choosing Mute at the top of the meeting window, or by choosing the microphone icon at the top of the Chat window.

You can also mute yourself or other callers individually. On the meeting roster, select the microphone icon next to the caller to mute. When a caller is on mute, only they can unmute themselves.
