How Do Call Blocking Apps Work on iPhone?

Call blocking apps integrate with iOS through the CallKit framework, allowing them to identify and block unwanted calls. Once installed and enabled, these apps check incoming numbers against their databases of known spammers and either block the call or send it to voicemail. This process occurs silently in the background, providing seamless protection without interrupting your daily activities. (idownloadblog.com)

Yes, iPhone users can utilize the built-in "Silence Unknown Callers" feature:

  1. Open Settings.

  3. Toggle on Silence Unknown Callers.

This feature silences calls from numbers not in your contacts, recent calls, or Siri Suggestions, sending them directly to voicemail. However, it may also silence important calls from unknown numbers, so it's essential to consider your needs before enabling this feature. (makeuseof.com)
