I have my voicemail set up with Google Voice. When I listen to a message, it will not play through my bluetooth headset (only though the phone or speakerphone). I have a Voyager Pro, which is not A2DP. Would the message play through the bluetooth if it was A2DP? Or is it a Google Voice thing? I thought the Voyager Pro was A2DP when I ordered it, but now I am thinking of returning it for a Blueant Q1.
