The president of FCC, Ajit Pai, is preparing a new set of measures against theft that the commission will vote during its next public meeting on June 6. The decision would force operators to make automatic calls by blocking an exclusion function for clients instead of an option -in feature Pai has a couple of suggestions for filtering methods, including one based on the customer's own contact list in your phone.

Speaking in general terms, the president talks about the filters derived from the "analytical and consumer white lists". The call blocking applications of external developers already use the existing data to place numbers in certain lists. However, more aggressive filtering, such as a system based on the contact list, will remain optional. Beyond that suggestion, consumer whitelists can take other forms.

Pai is also encouraging voice service providers to also adopt the STIR / SHAKEN standards, in which sending and receiving service providers perform verifications of callers and certify that their numbers are not counterfeit. In a blog post, he mentioned that operators wanted legal guarantees to implement these technologies, so he would also propose safe harbor exemptions for those companies if in the event that a robocall is not leaked by the STIR / SHAKEN process.

AT & T, Comcast and Sprint are working to implement STIR / SHAKEN later this year. T-Mobile implemented the standards in January, while Verizon activated them in March.

The president's rules do not oblige telecommunications companies to offer these services for free, although he does encourage them to do so.
