Several companies that made over 50 million deceptive robocalls to Massachusetts residents have agreed to settle charges, Attorney General Maura Healey announced Thursday. Healey joined with 38 other states and the Federal Trade Commission in going after the robocall operation, which collected more than $110 million over a number of years. In the calls, the companies claimed to be fundraising for various charities, but only gave about 10% of what they collected to the causes. Some charities received as little as one tenth of a percent, Healey said in a written statement. They also violated federal rules against using soundboard technology, in which an operator plays pre-recorded messages over the phone to trick people into thinking they're speaking with a real person.
