FCC President Ajit Pai is preparing a new set of anti-robocalling measures that the commission will vote on at its next public meeting on June 6th. The decision would force operators to opt for automatic blocking of customer calls. -in feature. Pai offers a few filtering methods, including one based on the customer's contact list on their phone.

In general, the president talks about filters derived from "white lists" of analyzes and consumers. "Call blocking applications from third-party developers already use existing data to place numbers on certain lists, but more aggressive filtering, such as a contact list system, would still be enabled. In addition to this suggestion, the white lists of consumers may take other forms.

Pai also encourages voice service providers to also adopt STIR / SHAKEN standards, according to which transmitting and receiving operators check callers and certify that their numbers are not falsified. In a blog post, he said carriers wanted legal assurances when deploying these technologies. It therefore proposed exemptions from the "Safe Harbor" for these companies in the event that an automated call would not be filtered through the STIR / SHAKEN process.

AT & T, Comcast and Sprint are working to roll out STIR / SHAKEN by the end of the year. T-Mobile implemented the standards in January and Verizon activated them in March.

The president's rules do not require the telephone companies to offer these services for free, although he urges them to do so.
