Frequently Asked Questions

I have the area code and the 10-digit number (866-828-9088) listed on my blocker, but still my phone rings. Why?

While blocking calls particularly in the U.S, you need to know that the protocol of the caller ID is slightly different each time you are called by a number. The number may appear as 8668289088, but it can also come through with a little variation in the start. Like 1 866-828-9088, or 01 866-828-9088, or even 001 866-828-9088. Hence, if you don’t want your phone to ring with a blacklisted number. Then you should try entering 1, 01 and 001 before the number as well. It will successfully do the trick for you.

How much better does this new model of CPR V5000 call blocker works, comparatively to the previous one?

The new model of CPR V5000 has some features of improvements over the previous V202 model. It offers amended power in the unit, to perform along with some VOIP providers. While the old model lacked such a thing. Not to mention, the extended limit of 5000 numbers, which are already pre-programmed into the blocker. Where the old model only had a limit of 200. With the block now button, it can block 1500 numbers, while the previous models could only block 1000.

If I want to block all landline numbers of one area code within a single action. Do I still get to block the remaining 1499 numbers afterwards?

You sure do. And to do so, you would only need to input (for instance, 876) the area code to block it. But sometimes international calls display differently and get mixed with country codes on the blocker device. Hence, I would suggest not to forget the 1, 01 and 001 formula before entering the number to blocking list.

Does the device still register calling numbers, if it’s turned off?

The unit will certainly not record any numbers, if you have ‘Unplugged’ it. However, it will still record all incoming calls, if you have pressed the ‘Voice’ button and selected the ‘Off’ option, after toggling through the ABC. Which can later on be entitled under, white list of important calls, or black list of nuisance calls. Therefore, it is suggested that after distinguishing between good or bad calls. Set it back up for English and in-service, by selecting the option ‘A’ on it.

Does the name of caller also appear on the device along with the caller ID?

No. On the screen of the unit, you will only see  the phone number being displayed.



To block unwanted calls, a reliable call blocker is a must-have device. The top 10 list of Landline Call Blockers, we mentioned in the list are not only practical and functional.
