Ringback Tone Volume and Distortion


I have several songs set-up to play as ringback tones for my callers but they are WAY TOO LOUD (!) and b/c they are soooooo loud, they are distorted. It is not a pleasure to hear them for my callers. How can I fix this to a normal volume so I am not blowing out my friends eardrums with distorted music? It should sound way better than this. Can someone help or can Verizon turn it down? I have clients calling my number-- it's embarrassing. THANKS !!!!
