While the system is announcing the list of conference participants after
the chairperson enters *69, the chairperson can execute the
commands in Table 33.

Features available to all participants
Self mute/unmute toggle
All conference participants, including the chairperson, can put
themselves on mute by dialing *19. While on mute, the participant can
listen to the conference. To unmute, the participant dials *19 again.
Because there is one command for mute and unmute, the system
announces to the participant one of two possible voice messages:
"Muted" or "Unmuted." Only the participant that activates the command
hears the mute/unmute announcement. The mute/unmute command is
available to those participants who dial into the conference and who the
chairperson brings into the conference using the dial-out command.
Stop or start music
This feature stops or starts the initial conference music, which is
possible only when the conferee is the first person joining the
conference. Dial *99. The first entry stops it, the second entry starts it.
