Unwanted Calls Bypass Traditional Call Blockers

By Greg Tavarez February 23, 2023

No one wants to come home after a long day of work to hear the landline phone ring nonstop with unwanted callers on the other line. Even traditional call blockers that are used to block unwanted calls from telemarketers, robocallers and other unwanted callers are ineffective.  




In fact, traditional call blockers are at best a 5% solution, according to imp's Landline Landscape Report. Out of the calls imp handled in Q4 2022, only 5% qualified as “blockable,” or a call that came from a known bad guy using the same phone number.  

To put that percentage into perspective, around 95 million people in the U.S. use a landline, with 7.2 billion calls reaching those landlines in December alone, according to the report. Of those calls, 85% are tagged as unwanted.  

That raises the question as to why such a low number is only tagged “blockable” when a high percentage of landline calls are deemed unwanted.  

Well, the problem is that these unwanted callers each have access to hundreds of possible numbers to call from. So, if a landline owner blocks one number, the unwanted caller will just call from another number. From there, it becomes a never-ending cycle.  

“Ninety-five million Americans rely on their landline phone. But these unwanted callers are jamming up the lines,” said imp President George Lightbody. “This means that not only are phones being used as an attack vector for scammers, but people are missing important calls from doctors' offices and pharmacies." 

That is why imp's Greenlist Technology focuses on callers that landline users want to hear from. With the Greenlist Technology, spam, scam, political, fundraising, debt collection and survey calls are stopped before a single ring. 

Imp, with its five-minute plug-and-play setup, works with all major phone brands and providers. It does not matter if the home phone comes in through a traditional hard-wired landline or is provided by a VoIP system.  

Stop those annoying unwanted calls and only receive calls from numbers that matter.
