What is Anonymous Call Rejection (*77)?

Anonymous Call Rejection

Anonymous Call Rejection (*77) enables you to block all incoming unidentified calls for as long as you want.

Among the calls that are rejected automatically are those identified as Anonymous, Private, or Blocked. The only calls rejected are those from sources that restrict their Caller ID information intentionally, including those using features such as Caller ID Block.

From time to time, the Public Telephone Switching Network (PTSN) is unable to transmit information from a calling party to a receiving party. In such cases, Caller ID systems might display a caller as Unknown, Out of Area, or Unavailable. This indicates that the Caller ID information is unavailable, not that it is being blocked actively. Such calls are not blocked by Anonymous Call Rejection (*77).

You can also block incoming call from numbers that you specify. For more information, see What is Selective Call Blocking?

To activate Anonymous Call Rejection:

  1. Pick up your handset and press *77. You should hear three quick, short beeps to indicate the feature is enabled.
  2. Hang up.

Did You Know?

  • When anonymous callers place a call to your home, they hear an announcement telling them to hang up, release their Caller ID information, and redial your number.
  • The feature remains activated until you choose to disable it.

To cancel Anonymous Call Rejection:

Press *87.
