I have a problem. When I connect n900 to my bluetooth device Jabra BT8040, when I receive a call N900 just vibrates. I hear the ringtone only in the bluetooth device. The problem is that I don't hold the bluetooth on my ears all the time and sometimes I can't hear that I am getting a call. There was no problem with the same bluetooth and N95 which was not in "silent mode" when connected to the bluetooth. Do you know if this is fixable?
