Conferencing etiquette

  • Choose a quiet location without distractions
  • Use a headset to eliminate background noise and feedback that your microphone picks up
  • If you will have your webcam turned on, keep in mind that BigBlueButton does not have virtual backgrounds. Sit in a place that has a background you are okay with other people seeing
  • Stay muted when you are not speaking to prevent background noise and feedback

Big Blue Button FAQ

Why am I having difficulty connecting after I try to join the meeting?

VPNs often prevent BigBlueButton from connecting properly. Try turning off the VPN and reconnecting.

BigBlueButton works best in Chrome and Firefox browsers. Try using one of these browsers and make sure you approve permissions for it to access your microphone and webcam when your browser asks for permissions.

Why is my audio not connecting?

If you selected join with MICROPHONE, then make sure you gave permission for BigBlueButton to access your microphone in your browser. Your browser will give you a prompt window, asking if you want to grant permissions.

Why won’t my video connect?

Make sure you grant BigBlueButton access to your webcam when your browser prompts you to give permission. If that does not work, try leaving the meeting and reconnecting.

Why is there no microphone button for me to speak?

If there is a picture of headphones on your user icon in the User list on the left side, you are in listen only mode. Click on the button with the headphones icon at the bottom of the screen. Click the same button again when it has a picture of a phone with a line through it. You will then be prompted to join the audio call. Select the join with MICROPHONE button.

How do I improve unclear audio?

If there is lag in video or audio, you may be having internet connection or speed issues. You can put BigBlueButton into data saving mode to help with clarity. Data saving mode will allow you to turn off webcams. Click on the three dot hamburger menu at the top right of your screen and go to settings. Select DATA SAVINGS and turn off "enable webcams".

Facilitator Guide

Leading Conferencing Rooms on BBB

Purpose: Breakout rooms are a time for event attendees to collaborate. It is a working session. Sessions are led by a facilitator, but do not follow a structured agenda.

Welcome attendees into the room, remind people to join with the audio microphone icon, not the headset (listen only) icon. If a person has an icon with a headset next to their name, they have joined via listen only.

Ask users to close the main meeting hall BBB tab in their browser while they are in the breakout room. As the facilitator, please make sure you also do this. Audio from any other open BBB meeting rooms in other tabs will come through the users computer audio and it will be heard in the breakout room.

Breakout rooms may be recorded. Prior to the beginning of recording, the facilitator should notify the attendees that the session will be recorded. If people do not want to be visible in the recording, they should turn off their video. The recording will only record user webcam video and audio input during the session. Recordings will not capture presentations, shared screens, public or private chats, or shared notes.

At the end of the breakout session, post the link to the main hall in the public chat so attendees can navigate back to the main room. Remind people to close the current meeting room window tab in their browser.

Copy the notes from the shared notes section and send them to the appropriate person for posting to the Gitlab group.
