(Salem, OR) -- The Oregon Attorney General has filed a lawsuit against Avid Telecom and its owner for making billions of robocalls. Over seven billion calls were made to numbers on the National Do Not Call Registry. Avid Telecom is a Voice over Internet Protocol service provider that sells data, phone numbers, and dialing software, so its customers can make robocalls. Besides being annoying, robocalls are often used for scams involving the Social Security Administration, Medicare, auto warranties, and others. In Oregon, it's against the law to call to make robocalls to numbers on the Do Not Call list.
