Step 2. Press the "Power" button twice (quickly) to reject an incoming call
If you are using an iPhone 6 or later, the "Power" button is located at the top of the right side. On previous iPhone models, it is located along the top side. This way the incoming voice call will be rejected and sent directly to the answering machine.
If you are using Apple EarPods or a compatible earphone model with a microphone, you can reject an incoming voice call by pressing and holding the button on the microphone for 2 seconds. You will hear a double beep to indicate that this call has been automatically sent to the answering machine
