H. Rept. 116-173: Stopping Bad Robocalls Act, Report to Accompany H.R. 3375, July 23, 2019 [open pdf - 392KB]
From the Purpose and Summary: "H.R. 3375 would take myriad actions aimed at relieving consumers from the onslaught of robocalls. Among other things, H.R. 3375 would require the implementation of nationwide call authentication technology so consumers can again trust the number that appears on their caller ID. The legislation also provides for carriers to offer call blocking services and requires it to be offered at no additional line-item charge, and directs the Federal Communications Commission (FCC) to issue rules to protect consumers from calls they did not agree to receive and to ensure consumers can withdraw consent."
