US Federal Communications Commission Chairman Ajit Pai will proposed giving mobile phone companies more power to block unwanted robocalls, according to a release from the FCC on Wednesday.
Pai's proposal, if adopted, would allow phone companies to block unwanted calls for customers by default.
According to the release, customers can opt-in or out of any blocking services they don't want.
Pai also proposed seeking public comment on how caller ID authentication standards, otherwise known as SHAKEN/STIR, could inform call blocking.
The SHAKEN/STIR framework would validate where calls originate from, where they claim to be coming from, and would allow for faster tracing of illegal calls to find out who's responsible for them.
Later today, Pai and four other FCC commissioners are set to testify before a US House panel over the growing number of robocalls.
