With Duo, all you do is call the person from the app. If you're on i OS, you get a push notification that someone's calling. On Android, Duo calls come through like phone calls, ringing loudly and taking over the screen.
If the person in your phone book, the Knock Knock feature provides live video before you pick up. Turn it back on and video should return, too— though it doesn't always cooperate.
Video also isn't conducive to modern communication.
Everyone texts, usually with emoji and GIFs and little punctuation.
