    In this section I will be telling U.S.A customers how to successfully program their
    CPR Call Blockers on Digital VOIP lines like Comcast, Cox Communications,
    Time Warner, Century Link, Century Tel, Verizon/Verizon FIOS, AT&T, Charter, etc.

    If any U.S customers experience programming issues with their Call Blockers,
    can you please try the following workaround methods before returning the product
    to wherever you purchased it from.

    Make sure the Call Blocker is set up correctly by using the LINE/LINE 2 and TEL/TEL 2 ports
    (LINE 1 and TEL 1 aren’t used overseas in the U.S.A).

    You need to program the Call Blocker using the IN-LINE connection below and
    then you should get red lights or an active LCD screen on the call blocker whilst
    you have an active dial tone. This confirms the unit is set up correctly and working.



    Q. Customer is stating that they can’t program any programming codes.

    A. You must have it set up IN-LINE (as above) for programming to work.
    If you don’t hear any beeps after the # keys, then there’s a good chance
    that your telephone provider’s call feature codes are conflicting with the
    call blocker and producing a fast busy signal before you can input the
    codes. There are a few things you can try to resolve this…

    1. Instead of getting a dial tone first and then inputting the programming codes,
    simply input the full programming code into the phone first
    (e.g * * 7 # NUMBER #) for adding a specific number and then dial the number
    as you would a normal call to see if the beeps respond in this way. If they still don’t and
    you get an error or a busy tone from the provider, then remove the main line cable from
    the LINE 2 port of the call blocker (LEFT SIDE) and put it into the LINE 1 port of the
    call blocker (LEFT SIDE). This may enable you to program it without it conflicting with
    the telephone provider’s codes.

    2. If that fails and you have a v.107/v.108 or v.201/v.202 Call Blocker, then you can also use
    the alternate programming code of # * 7 # NUMBER #. The v.107/v.108, v.201/v.202 model
    call blockers have an alternate way of programming the codes which shouldn’t conflict
    with the telephone provider’s codes. Start all programming codes with # * instead of * *.

    3. Another thing you can try is by programming the start of the programming codes
    (* * 7 # ) as a speed dial option with certain phones and telephone companies. If your
    phone or telephone provider has a speed dial function, try setting the above code as
    a speed dial and then try programming the unit in the ways mentioned above.

    4. Some phones (Panasonic 6.0 DECT) have phone buttons on the base station unit.
    Try programming the codes using the buttons on the base station rather than the
    phone handset itself using both * * and # * commands.

    5. If this fails, get a dial tone and press and hold down the BLOCK NOW button for
    5 seconds until it beeps and mutes the line (v.202 model only). You should then be
    able to input the programming codes without getting a fast busy signal. Try both * *
    and # * commands.

    6. Input the full code and number as normal * * 7 # NUMBER # and then dial it as you
    would a normal number. The call won’t connect because of the * and # codes but the
    number is stored on your call log as the last number you dialled. Then hang up the
    phone and get a fresh dial tone (press talk/green phone button if on a cordless phone)
    and press and hold the BLOCK NOW button for 5 seconds to mute the line. When the
    Call Blocker beeps and mutes the line, quickly press the redial/call button on your phone
    to redial the last number and it will go through and the call blocker should accept
    it as a valid programming code. If it fails, try the # * programming command in the same

    7. I have used this following method with an Ooma telco hub and it works fine. Pick up the
    handset without getting a dial tone and key in * * 7 # NUMBER # and ring the number as
    you would a normal call. The phone will go through a preparatory dialling sequence and
    dial the number in quick succession and the phone should beep and the call blocker will
    add the number to the block list (if you have v.202 model the screen will display the
    number on the callblocker, then as soon as you see it immediately press BLOCK NOW
    to add that number to the list). This works 100% so use this as a last resort if no other
    codes respond. This method also works with the PARALLEL setup and should
    work with all other VOIP providers too.

    8. If all of the above fails…please try to program the unit with an analogue
    corded receiver phone instead of a wireless DECT phone as these omit different
    dial tone frequencies. The codes should then go through. Wire it up as per the image below…


    Please make sure you try EVERY method above and also try BOTH of these
    codes with EVERY method listed above and one of them should enable
    you to program the call blocker.

    * * 7 # NUMBER #
    # * 7 # NUMBER #

    9. This method seems to work especially with Comcast customers so give this a try if all
    of the above methods have also failed.

    Dial your home phone number.
    Press the * key to quit the Comcast Message Service.
    Wait for a busy signal.
    Enter your desired Call Bocker programming code, such as * * 7 # 876 # to block
    calls from the 876 Jamaican area code.
    Enter any additional Call Blocker programming codes until finished.
    Then simply hang up.

    If this too fails, it could be because you are wired up directly
    through the cable router/modem. Please unplug and wire up directly
    through the main master socket/jack using a splitter on the wall and
    try again. Follow the diagram below for correct setup in this way…

    Please Note: Once you are in programming mode, you can manually add
    multiple numbers or programming codes at once. So for example, if you
    wanted to add the following numbers, you would do so as follows…

    * * 7 # (beep) 408 000 0000 # (beep) 408 000 0001 # (beep)
    408 000 0002 # (beep) * # (beep) 6 * # (beep) and so on with different
    blocking codes and numbers. This is handy, especially if you have issues
    getting into the programming mode via fast busy signals with your
    telephone providers as it saves you having to repeat the codes all the time.
