Disable cell calls and notifications while on Teams call in Android.
I don't see this issue, so posting as new idea.
When I am on a Teams call on my Android phone, I still get notification sounds in the background.
Also, if I receive a call to my cell number, it will ring through the Teams call until I decline it.
I moved from 3CX, which didn't allow these sounds or interruptions. So, I know it's probably a quick setting for you guys to add.
