As most people know, the Do Not Call Registry has so many exceptions (surveys, charities, supposed credit card companies, etc.) that it's useless for blocking spam. If you ever put your phone number on any online order, you've given the company permission it to phone number aggregators; I accidentally did this and started getting at least four spam calls a day. So I bought this blocker and I'm THRILLED with it. When my caller ID shows an unknown or spam ID, I click the button and the number is permanently blocked: it never rings again. (And if you have any problems setting up your phone--as I did--the company responds to e-mailed questions within 24 hours.)

Although I was skeptical at first I decided to take the dive and purchased this product. First my issue, constant callers from marketers and bill collectors looking for my son who racked up bills with them and who no longer lives with us.

Every single day we can 5-15 calls from scammers, spoofed numbers, cell phones, unknowns you name it we get it. I initially tried using the number blocking feature of my cordless phone but it had a limitation of 20 numbers, always rang at least once before silencing and since scammers change their number all the time that became difficult to manage. The national do not call registry is useless, answering the phone and threatening legal action is useless as well.

So here comes this product. It looked a little flimsy and it was shipped from overseas but that should not bother anyone. Easy to set-up, just make sure you connect it correctly and READ the instruction booklet it came with. So here is how it is suppose to work. A call comes in, you press the block button and it blocks the caller the next time they call.

Well I was unable to confirm that the pressing of the button actually works or not since I did not get a confirmation light from the LED's and the instructions were very vague on that feature. So I ignored the button feature and decided to use the program feature. Fairly simple, you pick up your phone press **7# and you hear a beep then enter the recent number you want to block and press the # key again and you get another beep that confirms that number is now blocked.

Guess what.... IT WORKS like a charm. After a few annoying calls I simply enter the numbers I want to block and BAM, they are blocked. its kind of funny to see these scammers try to spoof their numbers and change them but you will get pretty good at blocking "area codes" or just out of area numbers.

Be aware that it is important that this device be connected before any phones. Meaning you CAN NOT just plug it into an extension and expect it to work. If you have a prewired house and still using old phone service with extensions in each room you are going to have to change the wiring a bit. If you have cordless phones which most of use in the modern world have, this device MUST be connected before you main cordless unit.

I purchased the call blocker for my father in law who was scammed out of all his money. The scammer would not stop calling him not once but several times a day and from different numbers.
With limited sight my father in law was unable to read the caller ID so he would answer every phone call.
I purchased this unit about a month ago and it has done everything it was advertised it would do.
I plugged it in, added the phone numbers the caller was calling from and we have not had one harassing call from the scammers since. Adding the additional numbers was easy and no hassle.
If you have elderly parents or harassing calls yourself, I would recommend the call blocker.

Though both my wife and I have cellular phones, we have a primary landline through AT&T. Our home is fairly large so in addition to the main hard wired telephone (for use during a power outage) we have an additional 8 wireless phones along with an answering machine. We have had the same landline telephone number for a bit over 20 years.

The Federal Do Not Call Registry was great while it lasted. But today it appears to be a waste of time even bothering to list your number.

Like many others, we were constantly annoyed by the nuisance telemarketers, requests for political and "charitable" contributions, surveys, polls, etc. On average we would receive 4 to 6 nuisance calls a day. So when the phone rang, either my wife or I would have to put on the reading glasses to view the caller ID to decide whether to answer the phone or not. The really annoying part was to stop what we were doing (like exercising, cooking, working on a home project, not having our reading glasses handy, etc.)

My 91 year old mother that lives out of state usually calls 2 or 3 times a day. She gets a little lonely living by herself. I enjoy her calls. My wife is close to her sister whom also lives out of state along with daily calls from my wife's or my friends. So simply letting incoming calls go to voicemail is not a practical option and neither of us care to walk around the house with our cell phones glued to our hips.

If we recognized the phone number as an out of state telemarketer, we would let the call go to the answering machine. But that got to be annoying to listen to the phone ringing 4 times and hearing the prerecorded answer message played out only to be followed by silence after which the machine would answer back with a "Thank You For Your Call".

Day after day we had these nuisance calls. We tried answering some calls, listening to the long prerecorded message which might end with a "Touch 5 to have your number removed from our list". That didn't work, just a waste of time as our number never got removed and the calls continued unabated.

We tried answering some calls and hit 1 to speak to a live representative. As soon as we asked to have our number removed, the live representative would hang up and we continued to receive calls from the same number or company day after day.

So I tried many of the suggestions I found on the internet that would supposedly help reduce the volume of calls. For instance answer the phone and hit the star and pound keys followed by a hang up hoping that would fool the automatic dialers into thinking it had phoned a computer or Fax machine and bounce our number out of the system. That didn't work.

I tried the "hit 1 for a live representative" then when someone answered, I put them on hold. That didn't work. Heck, sometimes if we tried to hit 1, we would get disconnected since a representative wasn't available.

The final insult was when my wife asked the live representative "how can we get removed from your call list?" and the person replied "Have your phone line disconnected".

So I searched the internet and found this device. I read the reviews and ordered it. Since the unit is shipped from the UK, I spent the extra few dollars for expedited delivery. I received it within a week of placing the order.

The unit I received is the V.106 International model. Connecting it was a breeze. Though a little tricky at first, I used the provided preset blocking codes to block all "out of area/international calls", all "IP dialing systems which include Skype and other overseas nuisance call centers", all type "0 or single digit spoof calls", and all "private/unknown callers".

Then I went through the past caller list stored in the phone memory and blocked all of those previous nusance calls.

We saw an immedite drop in the number of nuisance calls getting through. As new ones came in we would simply cut them off and bock the number by hitting the button located on the top of the device. Or, if we weren't close to it, we would let the call go to the answering machine then use the "block last call" or review the caller ID list and block the number that way.

In the few weeks we have had it, those nuisance calls have dropped dramatically. This device works great.

It seems that once this device disconnects the call so quickly our number gets removed from their list. I can suspect that numerous telemarketing companies might use a common computerised database so when one telemarketer has their call immediately disonnected, our number then gets removed from a common or shared database. After only a couple weeks, we seemed to have been dropped by many telemarketers to the point we don't even hear one "single ringer" over a day or multple days. We are not quite to the point of not looking at the caller ID before answering but I expect it won't be much longer until we don't bother to reach for those reading glasses.

A couple things worth noting. When a call comes in from a blocked number, the phone does ring once while the caller ID is beng sent to the device. The device then immediately disconnects the incoming call. The call is disconnected so quickly after the device receives the caller ID, the incoming call is never logged by our phones.

Personally, we like to hear that single ring of the phone. It tells us the device has just blocked a nuisance call and we can chuckle about it knowing the device is giving us our money's worth.

If you are tired and frustrated by nuisance calls, this is the device you want!!! I would give it 10 stars if I could:)

CPR Call Blocker works great. Easy to enter numbers and blocks unwanted callers, and it really works. All you have to do is note the number of the unwanted caller and then enter it via one of a few simple options (i.e., "block last call", "enter the number yourself" or some others). From then on, no more calls from that number. When any call comes in, we hear one phone ring quietly and then if blocked, nothing and if not blocked the call comes through. Only negative is blocked calls show up once in the "missed call" log on our phone while calls through come through show up twice in the "missed call". Since we clear this log out regularly, this is not a problem compared to how well the CPR Call Blocker works. Now the only calls we get from unwanted callers are the first time they try or if they are calling from a new number. Once I enter them in the unit, no more calls. Well worth the price!

This call blocker is not compatible with either my Panasonic phone or my carrier - Cox Cable. After trying in vain to get it to work - it still blocked all of my incoming calls. Did more research and discovered the issues. Sent it back and, since it is shipped from England, cost me $12 to send it back. Kind of a big wash out.

Many basic telephone systems use the star key ( *) for various signaling purposes. [Examples: * 73 to CALL FORWARD, or * 63 to SELECTIVELY BLOCK your outgoing ID number.] The CPR Call Blocker uses the STAR KEY extensively and differently. That makes it incompatible. But if you have an analog phone system, a strong enough line signal, a single telephone instrument (no extension phones), and no conflicting "star key signaling options" on your phone line, it should work for you. The CPR Call Blocker has many praiseworthy features.

Since there are so many variables, my best advise is to inquire around within your own telephone area and find someone who has a call blocker that works well. Buy that model. That's how I found my current one. It was well worth the search.
