Getting Started with Teams Audio Conferencing

  • Call the audio conference phone number listed in the 'call in (audio option)' section from the Teams meeting invite.  You should hear a prompt welcoming you to the Audio Conferencing Center.

  • Next, enter the Conference ID followed by the # pound sign.

  • The automated voice will say "If you are the meeting organizer, press star now."  You will be prompted to enter your five-digit Teams PIN followed by the # pound sign.

  • The automated voice will announce "You are now joining the meeting as the leader."
  • NOTE:  When a meeting starts, the organizer needs to admit all dial-in users in the lobby to join the meeting. For example, if two participants try to join a meeting before it has started, they will be put in the lobby and will listen to music on hold, and when the meeting organizer joins using their PIN via phone, the meeting will start and the organizer can use the in-meeting command (press *21) to admit all dial-in users in the lobby.

Other System Generated Notifications

  • Is received when a user resets their PIN
  • Is received when a user's license is removed (sample shown)
