Schumer is backing legislation cleverly titled the Repeated Objectionable Bothering of Consumers on Phones Act - ROBOCOP - that would require phone carriers to offer free call-blocking technology to consumers.

It also would direct the Federal Communications Commission to require carrier verification that the caller ID information is accurate.

The aim of the FCC requirement is to prevent what is known as "spoofing" - using a familiar area code or phone-number prefix to entice consumers into answering robocalls.

In a conference call with upstate reporters, Schumer acknowledged that the 2003 “do-not-call” list is no longer effective. The list, the result of congressional legislation the same year, allowed consumers to insulate themselves against unwanted calls.
