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 take the call—and even use Real-Time Text (RTT) for your phone calls, if your carrier supports it.
