Additional meeting and call-related features and issues within Microsoft Teams for business
Again I think that's the issue EricF3_UB had/has, the original reported issue hasn't reoccurred at the company I work out for about 4 months now.
The original issue was Teams external meetings crashing out the audio driver of the device as opposed to no sound in Teams.
Sadly the company I work at wants to build company comms around this piece of software which has proved troublesome since it was brought out.
