There is an Apple feature whereby an incoming call to one iPhone device will ring also on other devices – phones, iPad, and even an Apple computer, if the following conditions are met:
- On both devices, the same Apple account is set up and activated.
- Both devices are connected to the same Wi-Fi
- The two devices are physically close to each other (for example, are in the same house)
Even if the user answered the call on the other device, and not the one on which the application is installed, the call will be updated and appear in the Num2 call.
