Return recent or missed FaceTime calls on Mac
You can quickly return a recent FaceTime call (including calls you missed) from FaceTime, Notification Center, a reminder, or the Dock. See FaceTime requirements.
Return a call from FaceTime
The left side of the FaceTime window shows you all the calls you’ve made or received (unless you deleted your call history). It’s organized by date, with the most recent calls on top.
The Upcoming section appears when you create a link for a FaceTime call or when a link is available in Calendar, Reminders, Mail, or Messages. These links appear in the Upcoming section for a day or so; otherwise, they appear in the date-based section—for example, Last Week.
In the FaceTime app
on your Mac, move the pointer over the call window, then click the Video button 
or the Audio button 
next to a call. (You can also click a call in the sidebar, then use the Touch Bar.)
Tip: A Group FaceTime call remains active until all participants leave the call. To join or rejoin a group call that’s still in progress, click the Join Video button 
.
Return a call in another way
On your Mac, do one of the following:
Return a missed call from Notification Center: Click the date and time in the menu bar at the top of the screen to see notifications, then click a call in the list of missed calls. See View app notifications.
Return a call from a reminder: In the Reminders app
, click the FaceTime button next to the reminder. (A reminder is created automatically when you decline a call and set a reminder to call back later.)Return a call from the Dock: Control-click the FaceTime icon, then click a call below Recent Calls.
If you don’t see the FaceTime icon in the Dock, you can add it.
You can’t call someone who’s restricted by communication limits in Screen Time.
