How to use calling features to block incoming calls

If you want to block a specific phone number (or calls during certain times), there are a variety of calling features you can use. If you've already activated a calling feature, but aren't having success, double check that you understand the purpose of the feature and you're using it correctly.

Blocking specific numbers

To block specific numbers, most customers use Call Rejection or Enhanced Call Rejection.

For these features to work, you MUST create a rejection list, and the number that you want rejected must be on that list. Calls from numbers not on your rejection list ring through to your home normally. If you remove every number from your list, this service automatically turns OFF until you turn it ON again and create a new rejection list.

Call Rejection and Enhanced Call Rejection work with most local, long-distance and wireless numbers. (Note: Not all wireless numbers supply the data required to make them rejectable.)

Troubleshooting Call Rejection:

  • Call Rejection must be turned ON to work. When you first order Call Rejection, it is turned OFF. To start rejecting calls, you need to turn the service ON and create a list of numbers you want to reject. Press *60 to turn the system ON and *80 to turn it OFF. 
  • You cannot include more than 12 to15 numbers, depending where you live, on the rejection list for this feature.

Tip: If you don't know the caller's number, activate Call Rejection immediately after you get a call from that person. To do this:

  • hang up,
  • pick up the receiver again,
  • press *60 and
  • follow the recorded instructions.

Troubleshooting Enhanced Call Rejection:

  • Enhanced Call Rejection must be turned ON to work. To turn it ON, call the CenturyLink Update Center at 888-(your area code)-8052* from any touch-tone phone, or call *78 from your home phone. (For complete instructions, download the Enhanced Call Rejection user guide.)
  • You cannot include more than 25 numbers on the rejection list for this feature.

Blocking certain calls

These calling features either require callers to unhide their phone numbers, or they stop calls from ringing through to your home during certain times of the day. In some cases, they let you block particular types of calls altogether.

Anonymous Call Rejection

  • Anonymous Call Rejection blocks ANONYMOUS and PRIVATE numbers only. If that's the kind of number you want blocked, this feature should do the trick.However, it does not block numbers that are missing data. These numbers show up on your caller ID as OUT OF AREA, UNAVAILABLE, UNKNOWN or NOT PROVIDED.
  • From the line where it's installed, dial *77 to turn it ON or *87 to turn it OFF. After you do this, you.ll hear an interrupted tone letting you know you.ve been successful.
  • For troubleshooting help, we have some suggestions for what you can do if Anonymous Call Rejection's not working

Caller ID with Privacy+

  • Caller ID with Privacy+ intercepts calls that don't contain Caller ID information. 
  • Callers can record their names, then you decide which calls to accept or reject. 
  • You should notice a reduction in the number of calls you receive, since most telemarketing callers will hang up without recording a name. 
  • To manage this feature, call 888-(your area code)-8052.** Select Privacy+ when prompted, and follow the recorded instructions.
  • For printer-friendly instructions, download the Caller ID with Privacy+ user guide.

Call Curfew

  • With Call Curfew, you can block ALL incoming (and outgoing) calls during the times of day you choose. The only calls that get through during those hours are calls you authorize.
  • Call Curfew is not designed to block specific numbers, but because it blocks ALL incoming calls, it can still be helpful if you're receiving harassing calls during a certain time of day.
  • To manage this feature, dial *78 from the line it's installed on, or call 888-(your area code)-8052 from any touch-tone phone.**
  • For printer-friendly instructions, download the Call Curfew user guide.

Dial Lock

  • With Dial Lock, you can block certain types of calls such as long distance, local, toll free, operator assisted, directory assistance and 900 numbers.
  • Dial Lock isn't designed to block specific numbers. However, if the number you want blocked falls into one of the Dial Lock blocked categories, that number will de facto be blocked.
  • To manage this feature, dial *78 from the line it's installed on, or call 888-(your area code)-8052 from any touch-tone phone.**
  • For printer-friendly instructions, download the Dial Lock user guide.

Do Not Disturb (DND)

  • With Do Not Disturb, you can block ALL incoming calls during the times of day you choose. The only calls that get through during those hours are calls you authorize.
  • DND is not designed to block specific numbers, but because it blocks ALL incoming calls, it can still be helpful if you're receiving harassing calls during a certain time of the day.
  • To manage this feature, dial *78 from the line it's installed on, or call 888-(your area code)-8052 from any touch-tone phone.**
  • For printer-friendly instructions, download the Do Not Disturb user guide.

No Solicitation

  • While technically No Solicitation blocks calls, it's actually more of a screening service.
  • No Solicitation screens your calls from 8 am to 9 pm every day. An automatic message asks solicitors to hang up and tells regular callers to press 1 to complete the call.
  • This feature relies on the ethicalness of the calling party to hang up if they're trying to solicit your business. In fact, anyone can press 1 and be connected to your home. If you're trying to block a harassing caller, this feature probably isn't your best choice.
  • To manage this feature, dial *78 from the line it's installed on, or call 888-(your area code)-8052 from any touch-tone phone.**
  • For printer-friendly instructions, download the No Solicitation user guide.

Security Screen

  • While technically Security Screen blocks calls, it's actually more of a screening service and requires callers share their phone number or be disconnected.
  • People calling from blocked, unidentified, toll-free and long-distance numbers hear a message saying that you don't accept unidentified calls. They're then given the option to enter their 10-digit phone number or hang up.
  • To manage this feature, call 888-(your area code)-8052.** Select Security Screen when prompted, and follow the recorded instructions.
  • For printer-friendly instructions, download the Security Screen user guide.
