BigBlueButton* is an open source software for web and video conferencing. With numerous functions such as a digital whiteboard, chat and video chat, screen sharing or the sharing of documents and notes, online business meetings and distance learning can be made interactive and easy.
Greenlight is an easy-to-use frontend for creating rooms, starting conferences and managing recordings. If you use an application with BigBlueButto*n integration, Greenlight can be uninstalled. A list of applications with BigBlueButton* support can be found on the BigBlueButton* website: https://bigbluebutton.org/inte...
Due to the WebRTC standard used by BigBlueButton*, a large number of UDP ports must normally be available for communication. Users from networks that restrict outbound UDP connections may not be able to connect to your BigBlueButton* server.
The TURN server enables such restrictions to be circumvented by the user establishing a connection to the TURN server and the TURN server then establishing a connection to your BigBlueButton* server on his behalf.

If attendees are having audio problems, make sure that the Broadband requirements are met. The bandwidth should be at least 1 Mbit / s in the download and 0.5 Mbit / s in the upload.
Make sure attendees are using an appropriate audio output device. If the audio is output through speakers, an echo may occur. The best solution is to use a headset to prevent the transmission of background noise and echoes.
