It worked only with my son who is connected to the same ISP NetCologne in the area of Cologne in Germany). Somehow I came to the DS-Lite tunnel, which could cause the issues and in-deed it did. I called the Provider and ask them to Change my Connection back to a full dual-stack Connection. They confirmed and provided me with a full IPV4 address instead of the tunnelled IPV4. They applied the Change to my Connection and to my router (AVM Fritzbox 7430). From this Moment on (since yesterday) all the issues are gone and I'm able to use a stable JamKazam session with my friend which was my goal. Maybe we have to finetunes things to minimize latency but in General it works now . So, no DS-lite, but a full IPV4 address for your router. The Change has the side-effect that I now can remotely Access my router and my home Network via mobile phone.
One of us has a Mac and other Windows 10 and everything works well between them. But other two of us look grey in the same session, with the message "No audio?" in their track. Curiously, one of them hears other person but not us. The warning message of no audio from some peers appears.
Could someone of you help us, please? Thank you.
Good luck.
