Audio and video disconnection problem

Hey bro,when two people use their mobile phones to make an audio or video call。Turn off the screen。one of them will automatically disconnect after a few minutes,why?and how to deal with it?


At the moment I have the same problem.
When 2-10 participants connect, they are all kicked out of the video conference.

I am in Kazakhstan.
Connected to eu-central-1

Check default settings

hello,which configuration should I check? thank you!
