A little more info as I have been playing around. I'm wondering if its not an issue with my Airave from Sprint. My wife is home as well so I called her phone. That means I placed the call and she answered through our Airave at home. I moved it around and she heard no beeps/tones/etc.
I then called a friend who is not here (and of course not on my Airave) and he can hear the tones. He said it "beeps" twice with a sound like the tones on the dial pad the moment I pull the phone from my cheek. I confirmed also that my phone seems to act normally when I put the phone to my cheek (screen shuts off) and comes back on when I pull it away with the person I'm talking to's name and phone number showing.
