I have literally tried everything to turn this off on my Motorola Cliq. I went to my home screen, clicked menue, then settings. I went to notification settings then to notification sounds. There is not a silent! I don't know how to make this sound go away!! I tried installing the "Missed Call" app, hoping that I could override the default settings on my phone, but it doesnt. Now I have two missed call notifications. Please help!!! Thanks in advance!
