 Here are some of the reasons consumers buy this product 

call blocking:

Fraud hurts 25 million people a year
Nearly 11 percent of the U.S. adult population is affected by fraud each year.

Robocalls complaints soar in U.S. and abroad
Telemarketing complaints in the US rose from 150,393 to nearly 4 million in 2012, according to complaint statistics from the US Federal Trade Commission (FTC) and Federal Communications Commission (FCC).

Increase in unsolicited telemarketing campaigns
Despite government efforts through schemes such as "do not call" lists, unwelcome telemarketers continue to make multiple calls to homes each day. Additionally, there is a loophole in the “do not call” rules that allow charities and political organizations to keep calling even if your number is on the do not call list.

Technology misused by scammers
Technology allows scammers to manipulate caller ID to hide the real phone number from which they are calling (also known as "spoofing").

Boycott from local phone companies
Call blocking services offered by local phone companies are inefficient and costly (requiring monthly recurring fees). Additionally, local phone companies are reluctant to adopt technology to block telemarketing calls because they fear it could block legitimate calls.
