In-Conference Controls

As a moderator (you entered the admin PIN) you get a live roster of everyone in the room and a set of controls to keep the meeting running smoothly.

What you can do

Mute / unmuteSilence a noisy line, or mute everyone but the speaker.
KickRemove someone from the room.
LockSeal the room so no new participants can join.
