When in "Concentration mode - Sleeping" all callers hear my line is busy!
This is very strange situation. When I enable "concentratrion mode - sleeping" everyone who calls me hears like my line is busy at the moment. (I dont hear anything ofcourse since all is muted etc.). This is not the way it should be obviously, they should simply hear that Im not answering to the call.
This is very bad, because then the person naturally calls back again and again and again, hoping that "my call has ended". I end up having dozens of call from people because they all keep calling me back again and again.
What is causing this? How to solve?
No, no setting in that mode has anything to do with this and I wonder how this is even possible, since I understand that "line is busy" mode is done at the ISP end, not the phones end...but apparently it is not - or is it? How is this possible?!?!?!?
