This is a Apple/carrier issue. the iPhone6 for some reason is not passing the voice on the AT&T network. I attached the phone to the bluetooth in my car, so none of the phone’s mics are in play. I can hear them, but they can’t hear me. I took the phone to the Apple store, and their Genius basically tried to have me spend $299 to upgrade the phone. I think I will upgrade the phone to an Android.
