I press the mode change button to put in music mode and then press the button in the middle of the volume control. This sends a pause to the phone and puts it in stereo headset mode. Sorry I can't remember the names of the buttons, don't have the manual with me. I keep it in music mode even when I'm only using the one side. That way I hear all the phone sounds in the headset. When I want to voice dial, I hit the mode button to put it back in phone mode and tap once for voice dialing and I hear the response in the headset.

I'm also using the unofficial 3.16 rom. With the official one, the headset always stayed in music mode for me. I only had to start doing the above since I upgraded.

I love the BT8010, the best BT I've had so far and was cheap when it was on sale for $30 at Frys a couple of weeks ago.
