Nomorobo is a third party program that identifies known robocalls and stops them after the first ring.
From Consumers Union: "Thanks to pressure from activists like you, Verizon recently decided to provide more help blocking invasive robocalls. Each year, consumers lose an estimated $350 million as a result of privacy-violating phone scams. This is a big step in the right direction by Verizon."
