How does it work?

Option 1: Create the meeting room directly in the ILIAS course or group

You can create the BigBlueButton meeting room directly in your ILIAS course or ILIAS group.
Using the green button "Add New Item" you can select the ILIAS object "BigBlueButton Meeting Room" and integrating it directly into your course/group.
Ideally, you use BBB directly with your participants in the course, so that everyone joins the meeting directly from ILIAS. In the meantime, it is also possible to invite external participants to a meeting via a link, see instructions below.
Information on the functions and possible applications of BigBlueButton further can be found below on this page in the tutorial and instructions.
1st Step: Button "Add New Item"
2nd Step: Select "BigBlueButton Meeting Room" item

Option 2: Using BigBlueButton outside ILIAS via BBB-Server

Since the winter semester 20/21, employees of the University of Freiburg can also use BigBlueButton without having to create a corresponding meeting room item in a course or group on ILIAS.
To do this, log on to with your university ID. You can then create and start rooms via this website. By sending the corresponding room links, you can invite other participants to the meetings.
This way you can, for example, hold conferences with colleagues or student fellows without having to create a course on Ilias.
1st Step: Open Website and login with Uni Account (Staff and students)
2nd Step: Create room, start meeting and share room link
The following tutorials describe functionality and procedures in detail:
In principle, BigBlueButton can be used in all known browsers, such as Chrome, Firefox, Internet Explorer and Safari. However, it is possible that individual functions do not work properly or are not available in certain browsers. The developers of BigBlueButton therefore recommend the browsers Google Chrome and Firefox for the best possible performance (cf.
In the following video, all functionalities of BigBlueButton are shown in overview (in English). Please note that the recording function is not activated in our BigBlueButton instance:

In the settings of the BigBlueButton room, you can also specify external guests for whom a direct link to the meeting room is then created.

Please note: The link will only work if a meeting room is actively open, i.e. the teacher as meeting moderator has already started the meeting. Therefore, arrange a fixed time with the guest at which he/she is to join.
To allow students to use BigBlueButton meeting rooms independently, your course must contain at least one group. There, students must be upgraded to group administrators in order to create and start BigBlueButton rooms themselves.

If you have problems using BigBlueButton, you will find known errors and their solutions in the following tabs.
If your error is not listed, please contact the e-mail addresses listed at the bottom of the page for individual advice.
The list is constantly being expanded.
BigBlueButton uses WebRTC (Web Real-Time Communication) technology, which is not supported by all browsers. For the best possible experience, we recommend using the latest browser versions of Mozilla Firefox or Google Chrome on Windows, Mac, Linux, iOS or Android. 
Safari version 11 or earlier (due to the lack of WebRTC) and Internet Explorer are not supported.
Under Windows, it sometimes happens that microphone access is not permitted for the browser. In this case, you would have to go as follows: Windows --> Settings --> Privacy --> Microphone --> ‘Microphone active’ and then explicitly authorise the browser you are using to access the microphone.
Occasionally, applications like Zoom or Skype might block the microphone, preventing both the browser and Windows from accessing it. In such cases, you should close the respective program.
Rarely, the browser itself might block microphone access. In such cases, click on the lock icon in the address bar and explicitly select "allow" for the microphone.
If you encounter connection issues, please check if your WiFi signal is strong enough. If necessary, connect a LAN cable to your device.
If the problems persist, you can activate the "Data Saver Mode" by clicking on the three dots at the top right of the settings tab. This allows you to disable webcams or screen sharing for yourself, while other participants will still be able to see them.
Currently, it is not possible to export annotated slides. You will have to use screenshots to save them.
