we have experienced a problem with MS Teams in different customer environments when wanting to reject a second incoming call in Teams Client. From time to time (cannot reproduce this) a second incoming call cannot be rejected, if the user clicks the reject button the incoming call popup goes away for a moment but immediately returns.
Has somebody experienced similar problems and knows the root cause of this issue?
Enabling busyonbusy is not an option. Second incoming calls should be allowed but rejecting the calls should just work.
