[Team] Jitsi improvements

Hi, i just did some improvements on our jitsi setup regarding buffers. I know we have still some problem with our jitsi setup but every problem we face gives us the chance to fix it and make this setup better. We hope and will see next week how good this Setup work now. We just tested Jitsi in general and it worked for us now so no diconnects anymore. We couldnt test it with large amount of people. Have a nice Weekend. BR Denny
