Conference Voice Menu

The conference voice menu lets anyone on a conference call control the call from their phone keypad, without needing the web interface or an app. You would use it to mute yourself, adjust volume, or (if you run the room) manage who is on the call.

While a conference call is underway, press the * key on your phone to open the voice menu, then press a digit to run a command. These keypresses travel as DTMF (Dual-Tone Multi-Frequency) tones, the standard beeps a phone keypad sends. The menu applies only to the conference room you are in.

The commands are grouped by who can use them:

• Moderator: the person who hosts the room. Moderators can use every command, including the ones that manage the room and its attendees.
• Participant: any other attendee. Participants are limited to commands that affect only their own audio.

Keys 2 and 3 act on the room and its attendees, so only moderators can use them. If a participant presses 2 or 3, nothing happens to the conference.

Voice menu options

Key	Action	Moderator	Participant
1	Toggle your own microphone between muted and unmuted	Yes	Yes
2	Lock or unlock the conference so no one new can join	Yes	No
3	Remove the most recently joined attendee	Yes	No
4	Turn the overall conference volume down	Yes	Yes
6	Turn the overall conference volume up	Yes	Yes
7	Turn your own volume down	Yes	Yes
8	Leave the voice menu and return to the call	Yes	Yes
9	Turn your own volume up	Yes	Yes

Conference volume vs. your own volume

Two pairs of keys change volume, and they are easy to mix up:

• Keys 4 and 6 change the conference volume, the shared audio mix that everyone in the room hears.
• Keys 7 and 9 change your own volume, which affects only what you hear on your handset.

Caution

Key 3 disconnects the most recently joined attendee from the call right away. It always targets the last person who joined, not a person you choose, so confirm who that is before pressing it. There is no confirmation prompt.

Tip

Once everyone you expect has joined, a moderator can press 2 to lock the room. Locking blocks any further callers from entering, which keeps uninvited people out of a sensitive call. Press 2 again to unlock if someone still needs to join.

When you are finished with the menu, press 8 to exit and return to the conversation.
