To silence all callers on the line, press once. To cancel a muted participant’s ability to un-mute themselves, press *6 again or twice in a row.
You may silence your phone from the call screen on an Android device. A mute button is included in the call screen (circled below). It’s a microphone with a line through it, and it has a slash through it. To mute or un-mute your hone, please click this button.
To unmute oneself. Hit the key that corresponds to your name. Participants may not be muted by hitting any keys. It is impossible to mute anyone. To resume open discussion mode. Repeat the process once again.
