To change the mute mode of your call while in your personal Online Meeting Room, simply click on the dashboard icon at the top of the screen and select 'Mute All' or 'Unmute All'. You will then have the option to allow participants to unmute themselves (Q&A mode) or prevent them from unmuting (Presentation mode). The same controls are also accessible via your telephone handset - for more information about this, please visit the following support link: What Conference Controls Are Available To Me?
