Filter calls in FaceTime on Mac
In FaceTime on your Mac, you can silence calls from unknown callers or calls identified as spam, and move those calls to separate lists in your call history.
Go to the FaceTime app
on your Mac.Choose FaceTime > Settings, then click FaceTime.
Do any of the following:
Turn on call filtering for unknown callers: In the Call Filtering section, select the checkbox next to Unknown Callers. Calls from unknown callers are silenced and moved to the Unknown Callers list in your call history. (Calling and data rates may apply.)
Turn on call filtering for calls identified as spam: In the Call Filtering section, select the checkbox next to FaceTime Spam. Suspected spam calls are silenced, moved to the Spam list in your call history, and hidden from the Lock Screen.
If you don’t want to receive any calls through FaceTime, sign out of FaceTime on each Apple device. See Sign in to or out of FaceTime.
Tip: You can also set up communication with your contacts only to avoid calls from unknown callers.
