what is a silenced call

A silenced call is a feature on iPhones that silences calls from unknown numbers and sends them directly to voicemail. This feature is called "Silence Unknown Callers" and can be turned on or off in the phone settings. When this feature is on, calls from unknown numbers will not ring and will not appear as missed calls, but they will be displayed in the recent calls list. This feature was introduced in iOS 13 and later versions. Silencing unknown callers can result in missed calls from new or unexpected sources, which may be important for personal or professional reasons. If you want to unsilence calls from unknown numbers, you can turn off the "Silence Unknown Callers" feature in the phone settings.
