Block a number on iPhone and differentiate from Silence Unknown Callers

How to stop a number from ringing your iPhone. Open the Phone app, go to Recents, tap the info button next to the number, and choose Block this Caller. That number can't ring you or leave a voicemail. Silence Unknown Callers is different. It only sends unknown numbers to voicemail. It does not block them.

Actually the Ask Reason for Call option is much better than the Silence Unknown Callers when it comes to Spam Control. Those calls will not be sent to Voicemail if the caller does not provide their name and reason for call, which basically eliminates those automated Spam calls that are unable to provide that information.

Blocking is completely ineffective when it come to Spam Control because spammers are simple "spoofing" the number and are completely made up where you would not likely even receive another call from that same number again.
