    With Call Block you can block up to 10 telephone numbers within your local calling area. Persons calling you from a number you have screened hear a recorded message saying you do not wish to receive calls. Call Block/Call Screening is feature that is available at a low monthly rate.

    Listen for dial tone.
    Press *60.
    You will hear the announcement that gives the current status of the Call Screening list.
    You will then hear recorded step-by-step instructions on how to add and remove numbers on your Call Block list, as well as how to turn the service on/off.

    Listen for dial tone.
    Press *60.
    Press #.
    Wait for three confirmation tones.
    Dial the 10-digit phone number you wish to add.
    Press # again.
    A recorded message will help you designate a list of numbers you wish to block calls from.

    Listen for dial tone.
    Press *60.
    Press *.

    Dial the phone number you wish to remove followed by * or remove a number by dialing 07 after it is read by the recording.

    Anonymous Call Rejection/Blocking (*77) or ACR intercepts calls from people who have used a blocking feature to prevent their name or number from being provided to people they call. When the ACR service is activated, callers hear a message telling them to hang up, unblock delivery of their phone number and call again. Your phone will not ring unless the caller removes the block.

    To activate ACR:
    Pick up the phone and press *77.

    To deactivate ACR:
    Pick up the phone and press *87.

    ACR stays on until you turn it off.
    If a call comes in from a private number on your Personalized Ring or Selective Call Forwarding list, the call will be accepted.
    ACR does not intercept calls that display as "Unknown" or "Out-of-Area" on the Caller ID. These designations usually mean that the call originated in an area in which Caller ID is not available.
    ACR does not block Operator Assisted incoming calls.
    Caller ID is required in some areas.

    If annoying or harassing calls continue, please contact us to change your phone number. Fees may apply.
