I am new to iPhone, coming from an Android 2.3 phone an I am noticing an annoying difference in feature, perhaps a bug. I have an iPhone 4S with a Plantronics Voyager Pro headset. When I place a call on my iPhone touch screen the audio automatically routes to my Voyager Pro perfectly... When I receive a call, I hear it ring in my bluetooth, I touch answer on the screen and I hear an audible like its answering and then I don't hear anything... I have go hit Audio Sources > Bluetooth to get it routed to my headset, so I have 2 steps to answer via bluetooth. On my old Android I touched answer and it would automatically route to bluetooth. Is this normal for iPhones? I am disabled with little arm movement so touching the answer button on the bluetooth itself is impossible for me. Thanks for the help.
