how to silence unknown callers

To silence unknown callers on an iPhone, follow these steps:

1. Open the Settings app on your iPhone.
2. Scroll down and tap on "Phone."
3. Scroll to the section titled "Call Silencing and Blocked Contacts."
4. Toggle on the "Silence Unknown Callers" switch (it will turn green when enabled).

With this feature enabled, calls from numbers not in your contacts, recent calls, or Siri Suggestions will be silenced and sent straight to voicemail. Your phone will not ring, but you'll still see the calls in your recent calls list, and the callers can leave voicemails if they wish. This helps reduce interruptions from spam or unknown callers without missing any important calls from saved contacts or known recent callers.
