Meta-owned WhatsApp can now automatically mute incoming calls if they’re from an unknown number, the service announced today.
The setting is available by going into WhatsApp’s settings, hitting “Privacy,” selecting “Calls,” and turning on the “Silence Unknown Callers” toggle. WhatsApp says the feature will help “screen out spam, scams, and calls from unknown people for increased protection.”
When enabled, the feature silences all signs of incoming calls from unknown numbers including both sound and visual alerts in the app. However, silenced calls will still appear in your recent calls list with a “silenced unknown caller” note next to them, in case you want to call back.
