Robocalls and scam calls are one of the biggest frustrations for Americans with landlines. Even if you’ve registered your number on the Do Not Call Registry, unwanted calls often continue. According to the Federal Trade Commission (FTC), Americans lost $10 billion to scams in 2024, with phone calls one of the most common attack methods.
A landline call blocking device can help—but not all are created equal. This blog outlines the essential features you should look for in a call blocker to protect yourself and your family.
Why Do You Need a Landline Call Blocking Device in the US?
The Do Not Call Registry only works for legitimate telemarketers. Unfortunately, many spam calls come from:
-
Fraudsters who ignore the law
-
Overseas robocalls using spoofed numbers
-
Charity and political exemptions that still allow calls
-
Persistent scammers targeting seniors
This is why call blocking devices are considered one of the most effective ways to cut down on scam calls.
Summary: The Do Not Call Registry alone cannot stop overseas robocalls, spoofed numbers, or scammers, making call blockers essential for US households.
What Features Should a Call Blocking Device Have in the US?
Here are the features to look for:
-
High blocking capacity – Store thousands of blocked numbers for long-term use.
-
Preloaded scam lists – Devices should come with thousands of known robocall numbers already blocked.
-
One-touch blocking – Lets you stop scam numbers instantly with a press of a button.
-
Robocall filtering – Automatically identifies and blocks robocalls before they ring.
-
Whitelist or trusted list – Ensures only approved numbers (family, doctors, banks) get through.
-
International and unknown blocking – Stops overseas scams and withheld numbers.
-
Caller ID display and call log – Helps track who is calling and identify patterns.
-
Compatibility with providers – Should work with US landline services like AT&T, Verizon, and Spectrum.
Devices like CPR Call Blocker integrate many of these features, offering a strong defence against persistent robocalls.
Summary: US call blockers should include high capacity, preloaded scam lists, robocall filtering, whitelist features, and compatibility with major providers.
How Can a Call Blocking Device Protect You From Robocalls and Scams?
Call blockers make a real difference by:
-
Blocking spoofed numbers used in IRS and Medicare scams.
-
Filtering robocalls before your phone rings.
-
Reducing the risk of fraud by limiting scammer access.
-
Giving peace of mind to seniors who may otherwise feel pressured.
Example: In 2025, the FCC warned of a surge in spoofed Medicare calls. Call blocking devices that automatically screened robocalls were able to stop thousands of these scam attempts.
Summary: Call blockers protect Americans by blocking spoofed IRS or Medicare numbers, filtering robocalls, and reducing fraud risks for seniors.
Conclusion
Landline call blocking devices are one of the most effective tools to protect US households from robocalls and scams. By choosing a device with strong filtering, whitelist options, and one-touch blocking, you can stop nuisance calls and safeguard your family.
