General Recommendations
Here are some generell recommendations for using our any video conferencing service:
- Make sure you have a stable broadband internet connection.
- Your home wifi is probably too shaky for real-time traffic; rather use one of these
- ISDN + Video = No No
- Use a headset! Your fellow participants will hate you for echos or white noise.
- If you are in a bigger meeting (>3 part.), mute yourself when ever you are not speaking.
- We recommend using Chrome or Firefox for all our services
- We recommend to disable all privacy plugins and if necessary disable your firewall (alternatively allow the WebRTC udp-ports)
- If you want to test your headset/webcam, you recommend this Testing Service
- Don't be like this ;-)
