    You would need a circuit to detect the ring with a microphone and tone-sensing circuit, and then momentarily press (short across) the answer key. This requires opening the phone and adding a couple wires across the answer key contacts. Can you do that? Alternately, you could use a solenoid to push the key mechanically but that likely would be difficult to get it to operate properly.

    Auto-answer used to be available on cellphones before smartphones. I'm wondering if there isn't an app for that?
