Stop anonymous calls, using *77.

Reject anonymous calls

FYI: This article applies to AT&T local phone service. Don't have traditional phone service? Select digital phone service or wireless service.

Anonymous Call Rejection (*77) stops calls from people that use a blocking feature to keep their name or number from being displayed. When Anonymous Call Rejection is turned on, callers will hear a message telling them to hang up, turn off the blocking feature, and call again.

Your phone won’t ring unless the caller removes the block.
