Just so I can make sure I understand the use case correctly, you have
several extensions on the Yealink phone, and you only want that phone to
get MWI notifications for specific extensions such as line 1 and 2? You
want the phone to not be notified of voicemails on the other extensions
such as line 3 and 4?
