FCC chairman Ajit Pai is preparing a new set of anti-robotic measures that the commission will vote on during its next public meeting on June 6. The ruling would be a carriers to make automatic call blocking and opt-out feature for customers rather than an opt-in feature. Pai has a couple of suggestions for filtering methods including one based off the customer's own contacts list on their phone.
Widely speaking, the chairman talks about filters derived from "analytics and consumer" white lists. At present, developers already use existing data to place numbers on certain lists. More aggressive filtering, such as a contact list-based system, would remain opt-in, though. Beyond that suggestion, consumer white lists can take on other forms.
Pai is also encouraging voice service providers to also adopt STIR / SHAKEN standards ̵
AT&T, Comcast , and Sprint are working to deploy STIR / SHAKEN by later this year. T-Mobile implemented the standards in January while Verizon turned them on in March.
The chairman's rules do not force telcos to offer these services for free, though he does urge them to do so.
