Anonymous Call Reject allows you to block calls from callers who restrict sending their Caller ID information. Often “Anonymous” is displayed for these callers. To use this feature:
Dial *77 to activate and wait for the confirmation tone.
All unidentified calls will then be rejected.
You must Dial *87 to deactivate this feature.
Important Note for Voicemail Users: If you use Anonymous Call Reject and activate Caller ID Block (*67) you must use the Voicemail access telephone number, instead of your home phone number when accessing Voicemail from home.
