Best thing to do is try to replicate the issue or speak with the user and see if you can replicate it while doing a debug. One thing to keep in mind is that you may experience issues if the device roams when on a call. This is default behavior of SfB and Teams. You can replicate this on any system by joining a call and walking around.
