Thanks Henrik,

I'll test this UA in a few hours - I used "Teams Phone Fix" addon to
Firefox, but it suddenly stopped working. Microsoft deploys its apps
partially - I can have some version, the person sitting next to me - the
other... and of course - they can work differently :)
Got the "User Agent Switcher" as well, beacuse O365 webmail looks like
the old Squirrelmail using the original Firefox UA (I suspect they have
some expressions looking for Mac, Linux and Windows - FreeBSD is out of
the league).

The easiest way to confirm web rendering depends on UA is to observe
Cam, Mic and "Download App" icons - one time they are grey, the other
both are active or one only :)

On Windows there is an option to make a Test Call within the Settings
menu - I haven't seen that on "spoofed" browser yet.
