I have a select few users that claim that Teams is not reliable for meetings. I am trying to determine why other than they refuse to transition from what they are used to (Zoom). I am looking at the Call Quality reports which shows <2% failure rate but need to understand what and how to read these to get a better understanding on what is a "failure" and how to determine if there is really a reliability issue with Teams. That way I can bring that back to our meetings. They can never provide examples, just say, there have been issues.
