If you’re trying to tap block a specific phone number, you should use a call-blocking device. This is a device that plugs into the phone’s wall outlet and is designed to intercept and then approve or block all incoming calls from private number.

These devices, such as the CPR V5000 or the Mcheeta Call Blocker, usually cost less than $100 and are simple to install and configure. To prevent your phone from ringing as frequently, they may use a combination of whitelists (phone numbers you have approved) and blacklists (numbers the device has been programmed to automatically reject).

If you’re getting spam calls or unwanted call from a variety of sources, there are a few different ways to stop them – but none of them are foolproof.

Start by adding your phone number to the National Do Not Call Registry if you haven’t already.

The Federal Trade Commission (FTC) maintains this database, which reputable solicitors use to avoid calling people who do not want to receive such calls. Unfortunately, the Do Not Call Registry is only used by reputable businesses, so it will not deter illegal spammers.

Next, contact your phone company to see what call-blocking services they provide. This is the best option for you. If your home phone is a VoIP (Voice over IP, or internet-based phone service) service that comes with your ISP’s internet service, your ISP may offer some online tools for managing unwanted call.

Even if you have a traditional landline that isn’t linked to the internet, your service provider may have options for blocking unwanted phone calls. These services are frequently included with your plan, but there may be fees.

Finally, if you want to reduce the number of spam calls you receive, never respond to incoming calls you suspect are from telemarketer. If you answer a robocall, even if you hang up a second later, you increase the likelihood of being called back in the future.

BT’s phones are by far the best option for blocking numbers on your landline. They do an excellent job of preventing nuisance calls from getting through, thanks to special TrueCall technology built in.

They will block numbers from a constantly updated database of cold callers and scammers, in addition to anonymous calls. Furthermore, a dedicated nuisance call blocking button is available on many of their handsets. It’s a satisfying feeling to press this and permanently banish cold callers from your landline!

Unfortunately, everything else about the phones fails to impress. The sound quality on BT handsets is generally much lower than that of rival models from Panasonic and Gigaset.
