[Android Central Question]

When phone is connected to the head set Bluetooth speaker on.Pushing buttons for voice commands to dial is not responding only with Phone 1,phone 2,on volume keys

What's not responding, the buttons or the voice commands? ("Turn the volume up" when you're on a phone call won't do anything - it's not supposed to.)
