VoiceOver FaceTime bug with IOS 6

Hello Everyone, Recently I have come accross a very frustrating FaceTime bug on my iPad 2 with IOS 6. Whenever I answer or place a call, the VoiceOver speech, instead of lowering in volume, becomes alarmingly loud as soon as the connection is made. Every time I touch the screen, I can hear the speech for a split second sounding like it should, but it than always crackles to a blaring volume. This is very distracting and unsettling. I was wondering if anyone else has experienced this bug or anything of the sort. If you have any suggestions please let me know. Thanks, Emsters18
