There are over 1.5 billion nuisance phone calls made to UK households every year, many are from overseas call centres using automated sales lists.
The CPR Call Blocker is pre-programmed with 200 known numbers which have been allocated as nuisance callers and will block any call originating from any of these numbers. The CPR call blocker will also reject any caller that is with-holding their number, so you will minimise any sales calls immediately.
A unique ‘Block Now’ button is located on top of the unit which when pressed, cuts off a caller in their prime with the number logged into its memory and permanently blocked.
The CPR Call Blocker is ideal if you don't want anymore calls from:
Recorded calls
Harassment or malicious calls
Overseas call centres
PPI calls

Its easy to set up and works with any home phone line, even if you have additional handsets or have a broadband connection.
The CPR Call Blocker is pre-programmed with more than 200 numbers which are 'deemed' as known nuisance callers. Companies which are selling by phone, using overseas call centres and automated sales lists are all pre-programmed which will minimise the sales calls you receive almost immediately.
The ‘Block Now’ button is located on the top of the unit. At the touch of a button the unwanted caller’s number is logged into the unit’s memory, the call will hang up and the number blocked permanently. This feature allows you to block up to 1000 unwanted callers as they are calling you.
There are also programmable functions that can be turned on or off including withheld blocking function, international blocking function, unavailable blocking function, VOIP blocking function, last calling number blocker, area code blocker and PPI calls blocker.

Rated 5 out of 5 by from Not sure about the last review... Many of the nuisance callers seem to think they are exempt from tps rules or just ignore them and hang-up when you tell them you're registered. I was getting between 10 and15 calls on a bad day, then they started at the weekend so although this seemed quite expensive it has been worth it. Having installed my CPR Call Blocker I'm now down to just a couple of calls a day and now I've programmed those numbers in (which is really easy - **7# number #) its only the occasional one that slips through. You can buy cheaper elsewhere but I live close to Maplins and couldn't wait for the mail order options.

Rated 5 out of 5 by from Simple set up Simple set up, instant blocking using "block now" button. NO crank calls for 2 weeks now! :-) Only possible problem is that international and withheld callers have to be set to block all or none as impossible to be selective (not makers fault). Withheld numbers could be from places like hospitals, work switchboards, etc. If you suffer from crank calls where caller ID is visible I can HIGHLY recommend getting one of these especially as Royal Mail junk deliveries are likely to be followed up with a call from the sender!

Rated 5 out of 5 by from Excellent purchased to stop unwanted calls, international, silent, with held numbers, and sales calls. We could receive 5 international calls a day, we get non now all blocked. We would regularly received silent and with held number calls - non now. Now whenever we receive a sales call we simply walk to the CPR blocker and press the button on the top. Over the 3-4 weeks I've owned the CPR Blocker the unwanted calls have dropped until we have non Great piece of kit, succeeded were BT and everybody else failed

Rated 5 out of 5 by from This device is unbelievable! We had been plagued with callers 'withheld', 'foreign' and all sorts, in fact most of our daily calls were unwanted. I bought this call blocker about two weeks ago, set it up and we have had not one unwanted call since. Very easy to set up. On our system, the line went in and out through line 2. It's all explained in the instructions. Very easy to set up. A 'magic bullet' for unwanted callers. We haven't had to press the button on the top to stop a call. We simply haven't had any since it was installed. Very happy.

Rated 5 out of 5 by from I was surprised at the small size of the unit but the ease of connection and set up was very satisfying, once the few codes had been entered and the unit was operating the silence spoke volumes. It has been an eye opener all the nuisance calls have stopped and if an occasional number does get through, you just enter that number directly into the unit and its never heard from again. Would recommend to family and friends.

Rated 5 out of 5 by from Great product I bought one of these 2 weeks ago and all of those solar panel, PPI, healthcare, accident and people offering to fix my slow computer calls have gone. Fantastic. It is so quiet now I have to keep checking my phone to see if it is still working. So easy to set up, was working straight out of the box within a couple of minutes. I would recommend downloading the instruction manual from the website as the one provided has very small print. Just one point, you can block "withheld" numbers, but some Doctors surgeries and Hospitals are using "withheld" numbers as well as friends who are ex directory. After an e-mail to CPR and a very quick response, I was told that you can ask people to add a 4 digit code to your number and that will bypass the call blocker. A very worthwhile buy if you are pestered by nuisance calls.

Rated 5 out of 5 by from This really works! Note though that YOU need to switch on the international blocking, plus it is also possible to make personal 'code' blocks - I've done this for 0845 and 0800 and 0500 numbers. Since installation all we have had are two single rings as it identified and blocked the callers - checking calls list after revealed they were 'international. We are signed up to mps online declining cold calls, but unfortunately this is not very effective as many companies have found a way round or ignore the system. We are only the second family in our house and with a 'new' phone number, but we were plagued with calls, especially for a Campbell family - who have never lived here! Sorry to them if they actually wanted those calls.

Rated 5 out of 5 by from To John - 03/07/2013 - Looks like you haven't set the unit up fully yet! You can 'fine tune' whatever numbers you want to block - even a whole area code if you wanted to. You can block 'bogus' numbers which begin with '0'. You can block withheld numbers, or international/unavailable numbers, VOIP numbers. All individually settable. Best little gizmo I ever bought!

If a number is blocked by user error ( if I press the block button but didn't mean to) does this device allow me to UNBLOCK a specific number so it works again ?

Asked by: Steve G
Erasing one Number from the "Blocking" list 1. Get a dial tone and input * 6 # you will hear a ‘beep’ 2. Then enter the telephone number you wish to delete followed by the # key, you will hear a ‘beep’ to confirm success. 3. Hang up to complete setup. Full instructions for the device can be found here

Does this product cut-off outgoing calls at pre-set time i.e. 59 minutes. if not, can you recommend me a phone adapter that will cut-off outgoing calls after 59 minutes.

Asked by: Dalwinder
On this occasion Maplin do not stock a product that exactly meets your requirements, or indeed anything close enough to offer you as an alternative.

The call blocker has blocked all withheld numbers (which is great), but some 'unavailable' callers are still getting through. Is there a way to block these manually? I am not always near the phone to press the 'block' button when these calls come through.

Asked by: Phyl
No, I am sorry but the item will not work for this use.
