There are also self-review measures. Both the FCC and the Justice Department have to create a working group that will study enforcement of certain robocall bans, and report to Congress. Likewise, the FCC will have to examine its policies on number resources to see if it can reduce access to spammers.

This isn't likely to completely stop the deluge of robocalls. Perpetrators that are willing to use real numbers (including hijacked ones) or find clever software tricks might still get through, and some may be willing to take risks knowing that the payoff from successful scams could be high. And remember, this only applies to illegal calls. "Rachel from cardholder services" might not bug you, but your cable provider will with your permission. This is more about creating a barrier that could deter 'casual' spam calls.
