This has happened to me only once this far.... I was listening to music over bluetooth headset when I needed to call someone so I used the Voice Control to dial my contact, and the music I was listening to carried over...at about quarter volume... to my call... when this happened did the person I was calling didn't pick up so I'm not sure if they would be able to hear it as well during the call.... tried dozens of calls since and hasn't happened again... anyone else have this happen?
