Mute or Unmute Yourself

To mute or unmute yourself, click Mute Mute or Unmute Unmute.


You can also use the keyboard shortcut Ctrl + M for Windows or Command + Shift + M for Mac to mute and unmute yourself.

If you want to speak while muted, you can hold the spacebar down to temporarily unmute yourself. When you finish speaking, release the spacebar to mute yourself again. If the meeting or event host doesn't allow participants to unmute themselves, you receive a notification.

If you try to speak while muted, a message appears letting you know to unmute yourself first or to raise your hand to let the host know that you want to be unmuted.

You're muted notification

If you use your computer for audio in meetings and events, you can mute and unmute yourself using your headset controls. Your mute status appears in the meeting controls and the Participants panel. Similarly, muting and unmuting from the desktop app also affects your headset.

If the host has prevented participants from unmuting themselves in Webex Meetings or Webex Events, you can only unmute yourself after the host sends you a request. When you get the request, click Unmute me. To keep your microphone turned off, click Stay muted.

Mute Background Noise

The Webex Meetings Suite applications automatically detects background noise coming from your microphone and gives you a notification to let you know.

Background noise detection prompt

If you turned on the Remove background noise feature, Webex Meetings and Webex Events separates your voice from background noise automatically. You won't see the background noise detection notification.


When you see the background noise notification, click Mute.


If Webex Meetings detects background noise by mistake, click Not a noise to ignore it.


(Optional) If you don’t want to be warned about background noise coming from your microphone, click Disable noise detection.

Mute While Sharing

When you're sharing, click Mute Me on the Meeting or Event Controls Panel at the top of your screen to mute your microphone.

Muting from the sharing toolbar

You can also press *6 on your video device to mute or unmute yourself.

Mute Others as a Host or Cohost

If you're the meeting or event host or cohost, you have options to help you moderate your meeting. You can mute individuals or everyone at once, prevent participants from unmuting themselves, and mute participants automatically when they join. Muting participants is useful when you hear background noise or when participants speak out of turn.


To mute or unmute specific people, go the Participants panel, find their name and click Mute Mute or Unmute Unmute. When you click Unmute, you send a request to the participant that asks them to unmute themselves.


To mute everyone but yourself and the presenter at once, open the Participants panel, and then select Mute all or Unmute all.


To mute participants automatically when they join the meeting or event, go to the Participants panel and click Mute on entry.

Prevent Participants from Unmuting Themselves

For Webex Meetings, you can choose to prevent attendees from unmuting themselves until you grant them permission to.

In Webex Events (new), these settings only apply to panelists.

From the Participant panel, click More options and uncheck Allow attendees to unmute themselves.

When unchecked, attendees can't unmute themselves until you allow them to.

Allow attendees to unmute themselves menu option

Use Moderated Unmute Mode

Moderated Unmute mode is available for Webex Meetings on versions 41.2 and later sites. This feature is also available for Webex Events (new) on versions 41.4 and later sites.

Moderated Unmute mode allows hosts and cohosts to unmute participants directly instead of prompting users to unmute themselves. For example, a teacher may unmute a student when they call on them. Meetings and events in Moderated Unmute mode have an indication at the top of the meeting or event window to let everyone know.

If your administrator has enabled Moderated Unmute mode, you can schedule meetings and events with it, or enable it for Personal Room meetings.

Click Unmute Unmute icon in the Participants panel next to name of the participant that you want to unmute.


Currently, hosts and cohosts can't directly unmute participants who joined from a cloud-connected video device or from the Webex app. When you click Unmute, you send a request for the participant to unmute themselves.

Participants who join a meeting from versions of the Webex Meetings mobile app earlier than 41.1 still receive a prompt to unmute.

If the host mutes a participant who joined using a SIP phone, the participant must press *6 to unmute themselves.
