Make and receive phone calls in FaceTime on Mac
When you want to make or receive a phone call, you don’t have to reach for your iPhone – you can use your Mac. When someone calls you, a notification appears on your Mac and you can anser the call — and even use the National Relay Service (NRS) for your phone calls, if your service provider supports it.
