The drafts may be more aggressive. Rep. Frank Pallone's Stopping Bad Robocalls Act would address some of the complaints that led to a court shooting down an FCC rule in March and set concrete goals. It would clarify the definition of a robocall, set clear exemptions, create a national database of reassigned phone numbers and require the FCC and FTC to work together on reducing spam calls by "at least" 50 percent year-over-year.

Rep. Debbie Dingell's CEASE Robocalls, meanwhile, would remove the common carrier exemption that prevents the FTC from taking action against providers who abuse robocalls. Smaller VoIP carriers have been "heavily involved" in robocalls, Dingell said.

These three proposals certainly aren't guaranteed to become law. Even if all three are completed, they'll still have to get Senate equivalents and pass both sections of Congress before they can be signed into law. If they do clear these hurdles, though, regulators would have considerably more authority to slap down robocallers. While there's no doubt robocallers will persist, the ideas would at least draw a clearer line in the sand for potential offenders.
