Robocalls, those annoying phone calls with automated sales pitches, continue to irritate consumers despite laws to limit the calls.
Richard Berman listed his landline on the National Do Not Call Registry, and those calls have pretty much stopped.
"However, I'm still getting two or three calls a week on my cell phone," he said.
To limit nuisance telemarketers, consumers can also register their mobile phones on www.DoNotCall.gov.
Charities and political candidates are still allowed to call, and some unethical telemarketers keep calling anyway.
"The problem is that enforcing the rules on unwanted marketing calls is tough," Margot Gilman with Consumer Reports said.
To help limit such calls, you should hang up and not press any buttons, according to Consumer Reports. By pressing numbers, as the robocalls often instruct, verifies to the autodialer that a real person answers that phone and the calls are likely to continue.
Another way to combat the calls is a new free service called Nomorobo. It identifies robocalls and hangs up on them after the first ring.
It is available only for internet-based phone services and those provided by cable companies. Consumers can sign up through www.nomorobo.com.
When blocking robocalls, essential alerts like school closings and flight changes will still get through.
