You can connect to a Microsoft Lync Online communications software conference call, or to the audio portion of an online meeting, by calling in. You can dial in either as a participant, or as the conference call leader. Both leaders and participants can use dual-tone multiple-frequency (DTMF) commands to manage the conferencing experience.

Note:  In Lync Online and the Online Meeting Add-in for Microsoft Lync 2010, conference call leaders are referred to as presenters. The meeting organizer is automatically a leader.

What do you want to do?

Join a meeting or conference call by phone

For most Lync conference calls, joining is as simple as dialing the conference call number. As soon as you’re connected to the call, you can mute your line or hear a list of people on the call by using DTMF commands.

The following table shows the typical DTMF commands available to participants during a conference call:

DTMF Code

Description

*1

Privately play a description of the available DTMF commands

*3

Privately play the name of each participant in the conference

*4

Mute audience, or return mute control to participants

Important:  Turning off audience muting does not unmute individual participants. When you turn off audience muting, participants hear a message explaining how to unmute themselves.

*6

Mute or unmute your microphone

*7

Lock or unlock the conference

*8

Admit all participants currently in the lobby to the conference. After you issue this command, everyone joining the meeting bypasses the lobby.

*9

Enable or disable announcements for participants entering and exiting the conference. Announcements are heard by everyone in the meeting
