I just discovered this problem the other day. I'm on a call using my bluetooth headset and as soon as I receive another call (call waiting), the audio cuts out in my headset, however the person I'm talking to can still hear me. The only way to get it back is to toggle the headset off then back on using the button on the dialer (bluetooth audio off, bluetooth audio on). Is anyone else experiencing this? I looked around and don't see any other reports.
