The Roboblock Act would require all voice service providers, such as phone companies, to offer robocall-blocking services to their customers at no extra charge. The Federal Communications Commission would have 180 days after the bill's enactment to write regulations establishing these requirements. The bill defines robocalls as automated calls or text messages made using equipment or artificial voices, and specifies that the blocking service should target calls that are highly likely to be illegal. This legislation would directly benefit phone customers by providing them with a free tool to filter out unwanted robocalls, a widespread problem that affects millions of Americans annually. No specific funding is allocated in the bill, as the requirement would be implemented by existing phone companies rather than through new government spending.
