Click the Start button next to your desired conference.
Join the Audio
Before joining a conference, you will be asked how you want to join the conference audio: via microphone or listen only. Listen Only allows users to quickly join the conference as a listener only (no microphone check). You will be able to change your audio preference once you've joined the conference.
Chrome Microphone Permissions
If you are using Chrome, you will have to accept a Chrome-specific permission for access to your microphone. This prompt is just below the address bar. Click the Allow button.
Firefox Microphone Permissions
If you are using Firefox, you will have to accept a Firefox-specific permission to access your microphone. Choose your microphone from the Microphone to share drop-drown menu  and click the Share Selected Device button .
Note: If you don't see the list of microphones, click the microphone icon  to the left of the address bar.
It is recommended that you use a headset with a microphone for best audio experience. To ensure your audio is working correctly, complete the private audio echo test. Speak a few words and if you hear audio, click the Yes button . To choose a different microphone and repeat the audio test, click the No button . If you need help with your hardware, click the Question Mark icon .
Use Conference Interface
The conference interface contains a variety of tools to help you moderate your presentation. Each area of the interface is created within its own window and can be resized.
Moderators have improved functionality and control for recording conferences. Instead of starting the recording immediately after the first user has joined, conferences includes a start/stop button so moderators can control the length of the recording. After the conference session is over, the recorded segments will be published as one recording.
After joining the conference and setting up your microphone, moderators receive a reminder notifying them that they can record the meeting, but they must click the recording button to start the recording.
Note: You must select the record option when creating your conference in order to see the recording button.
The Users panel  displays the users in the conference. To locate the presenter/moderator, look for the presentation icon next to their name. When you are the presenter/moderator, you can switch the Presenter by highlighting the name of a user in the User list and clicking the Change Presenter button .
You can mute or unmute yourself, and if you are the moderator/presenter, you can mute everyone . You can also kick a listener out of the conference by hovering over the listener's name and selecting the x that appears to the right . The lock icon  indicates the moderator has locked viewers from accessing certain features.
At the bottom of the Users panel, click the user settings icon  to Lower All Hands, Mute All Users, Mute All Users Except Presenter, or Lock Viewers.
Sharing Media Tools
In the left corner of the title bar, you can share your desktop , join/leave audio , share your video (webcam) , record conference , and mute or unmute yourself .
Note: Desktop sharing is not currently supported on Chrome running under Mac OS X. It is recommended you use Firefox to share your desktop.
Sharing Presentation Tools
At the bottom of the viewing window, you have several options for your presentation.
- To add files to your presentation, click the Upload Presentation icon .
- To advance or back up your presentation, click the arrow keys . The number between the keys indicates the number of slides in your presentation.

The Chat window contains the welcome message  for the conference and contains all the chat messages throughout the conference.

Resize Conference Windows
Each window within the interface is independent of the others. You can resize the windows to personalize your viewing experience. To change the size of a window, hover over the edge of a window until the cursor becomes a double arrow, then click and drag to your desired size.
To leave the conference, click the log out button or close your browser tab or window.
Note: Unless you set up a long-running conference, the conference will end automatically once the last user has logged out of the conference. It may take a few minutes for the Conferences page to reflect that the conference has concluded.
