"It remains uncertain whether the proposals will stem the flood of robocalls, and how much, if anything, consumers will pay for call-blocking services. FCC chairman Ajit Pai said the proposals “would likely greatly increase adoption” of call-blocking technology.
He encouraged phone companies to provide the service free, noting that fewer robocalls would also mean fewer complaints from customers and less spam traffic on their networks. But he stopped short of proposing to mandate that the services be free. He also said the proposals are designed to ensure emergency calls wouldn’t be blocked."
Doesn't sound like they are hell-bent on mandating the tech be applied. & my take was it will take some time for the tech to mature & the IEEE piece implies the same. Still, it sounds nice.
