    Pick up the receiver of the phone on which you do not want to receive anonymous calls. Wait until you hear a dial tone.

  2. Dial a code

    Dial *77 on the phone. Listen for a beep or confirmation message to let you know that the feature has been activated.

  3. Hang up

    Hang up the phone. The feature remains activated until you turn it off.
