You can use Siri to answer an incoming call on your iPhone or Apple Watch (with cellular) if you have a pair of AirPods, Beats headphones or a car with Bluetooth is connected. When you receive an incoming call, you’ll hear a ringing tone interrupt whatever it is you’re already listening to.
When you call a dead phone does it ring?
Answer: A: With a dead battery it should not ring but it should go to voicemail directly.
