Hearing background noise when ringing
 

This is weird, sometimes when my phone rings I can hear the person calling in the background BEFORE I answer my phone. This happens mostly when I get calls from other Sprint users (I am a Sprint TP2 user). An example would be if my wife calls me while I am grabbing my phone I can hear her singing along with the radio in her car before I answer...it's crystal clear!! This could be real bad if you were to say something about the person you are calling (not that i would EVER do THAT).

Anyone else seen this? Anyone have a solution?
