No Caller ID: The caller has actively chosen to hide their identity. Unknown caller: Your phone or carrier cannot determine the caller's information, often due to technical reasons. Blocked number: A specific phone number has been manually blocked by you or flagged by your phone/carrier as spam.

Dialing *77 activates Anonymous Call Rejection, blocking incoming calls from private or blocked numbers on landlines and some mobile services, making anonymous callers hear a message that you don't accept their calls.
