Please note that additional installed browser plugins (such as an ad blocker) may block the WebRTC standard. In addition, the WebRTC standard has to be enabled in the browser (e.g. via a company policy).    

To use the webinar room, we recommend Google Chrome and Mozilla Firefox browsers in one of the last two versions. Browsers such as Internet Explorer, older Microsoft Edge versions and so on do not meet the technological requirements. Apple Safari can be used to participate, but screen sharing has to be enabled locally for this browser. The current Microsoft Edge browser can be used without restrictions, as it is based on Chromium. Further information can be found in our ​technical requirements​.             

WebSocket connections (via https) are used for communication between the edudip servers and the user’s browser. An additional https connection to a media server is established for the transmission of audio/video. If no connection can be established, an attempt is made to tunnel the connection using a TURN server.

For seamless use of the edudip webinar room, it is necessary to enable all of the following listed domains with the respective transport protocols and ports in the firewall(s) and/or proxy servers. Communication must be possible without obstruction. For example, if you use “Deep Packet inspection”, it must allow WebRTC and WebSocket connections for the specified domains.
