The Skype-certified program for headsets in Skype for Business required a Skype-certified headset to do a minimum of three things:

1.  Set itself as the default audio device in the Skype for Business client.

2.  Provide device metrics into the Quality of Experience report.

3.  Have a USB HID multi-function / call control button to answer and hang-up Skype for Business calls directly from the device.

I don't get why we spent so much time getting this right in Skype for Business, only to throw this away in Teams. #3 was a long time coming, but now finally works - can we please fix #1 to ensure that a certified headset sets itself as the default audio device in Teams as soon as it is connected, i.e. the way it used to work in Skype for Business.
