Yesterday I tried to call my colleague via Microsoft Teams web-app 
(latest Firefox on CURRENT, spoofed User-Agent). Yes, there is no audio 
and video at all in both directions.

If I run desktop version with linux strace and it crashes. I think it 
because of unimplemented cgroups calls. Both Microsoft Teams and Skype 
are Electron applications, that tries to run chromium in isolated 
environment.
