If you would like to filter out calls from people who have blocked their contact information from appearing on your call display, use *77. When an anonymous caller attempts to call you when this feature is activated, they will hear a message informing them to hang up, remove the call display block and call again.
Anonymous call reject will only work if BOTH the name and phone number are blocked. For example a call from “Unknown Name: 555-555-5555” will go through.
To use this service, you must be an Anonymous Call Reject subscriber.
