Is it possible to configure Teams and/or Android to be able to answer a Teams call from the Android lock screen? If so, how?
Yes it should work, however it is a global issue and only appears to be working on some Android versions or if you're using a Developer preview of Teams, you can follow along the thread below about the same question:
I’m afraid that it is not supported.
I tested in my Android client. When the screen is locked, the coming Teams call was not shown on the screen and I cannot answer it.
I also check the notification settings on my mobile and it has no problem.
