I made some short mp3 tones from my music collection and bluetoothed one to my wife's C5212 for a call tone. It was far too quiet, so I increased the dB until it was +12dB. It was hardly any louder at all. I'm puzzled - can anyone explain why this is and if there is a way round it? I should add that I'm not familiar with the phone as it isn't mine.
