In a WebEx audio conference, you can use either your telephone or your computer to connect to the audio portion of your meeting. If you are a host, you can invite up to 500 attendees to participate in the audio conference. Participants can choose how they want to connect to the audio conference. They are prompted to choose:

  • Telephone—use your telephone to receive a call-back or to dial in, or
  • Computer—After joining the conference, participants can switch between audio connection modes with little or no listening interruption. In a mixed-mode audio conference, where some participants are using the telephone and others are using the computer, up to 125 people can speak.

Use the Participants Panel

The Participants panel allows hosts and participants to manage their audio and communicate effectively during the meeting.


  • Phone icons identify participants connected through the telephone.
  • Headset icons identify participants connected through their computers.
  • Clicking the microphone icon next to a participant's name mutes or unmutes that participant's audio.

Note: Participants can mute their own audio. The host can mute anyone's audio.

  • A red “x” and a highlighted microphone icon identify muted participants.
  • Sound waves indicate an “active talker” or a connection that is producing noise.

Optimize VoIP Audio Connections

WebEx integrated audio enables meeting hosts and attendees to use the Internet to connect to the audio portion of a session. Because a large number of connections can place a high demand on bandwidth, you should follow the guidelines below to maintain audio quality.


As a participant:

  • Test your audio setup in a practice meeting, especially if you have never used WebEx or are using new hardware.
  • Close any applications not being used to free up bandwidth on your computer.
  • Disconnect and then reconnect your audio if you experience a noisy connection or if other participants say they hear an echo.


As a host:

  • Select Mute on Entry from the Participant menu for large meetings.
  • Do not play music over an active connection, and eliminate as much background noise as possible.
  • Encourage hosts, presenters, and participants to use a headset with a good microphone.
  • Conduct a practice session to determine the correct sound levels.
  • Avoid speaking during slide transitions to help manage bandwidth utilization.
  • During scheduling, select the option to allow attendees to join before the meeting starts so they can test their audio.
  • Look for the “active talking” sound wave indicator in the Participants panel to identify where background noise might be originating.
