If you have experience with landline phones, you might know that there’s a simple way to achieve this. It’s called “continuous redial,” and simply entering a code (*66) after a busy signal will tell the line to keep redialing each time a call fails. A simple three-presses of *86 then stops continuous redial.
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.
