Also the sound seems to register itself as a media sound, so it will hijack your play/pause functionality. If I'm playing music and get a call, pressing play/pause to stop my music will just stop the ringing while continuing to play the music. Additionally, if I get a call and pick up, later on if I hit play/pause it'll continue playing the Teams call jingle instead of my music.

It can even be seen in Big Sur with the new playing media icon in the top bar. If I click that I can see that there's an item for my music, and an item for Teams sounds.
