According to Pai, carriers have avoided deploying default call-blocking tools because they have been unsure if such tools would be legal under the FCC's current rules. So, launching an initiative backed by the FCC that would encourage these companies to block robocalls by default could be a big help in preventing unwanted phone calls.
“By making it clear that such call blocking is allowed, the FCC will give voice service providers the legal certainty they need to block unwanted calls from the outset so that consumers never have to get them,” Pai said.Last year, Pai asked companies to adopt a "call authentication system" that was aimed at ending the use of illegitimate spoofed numbers, which many robocalls use to trick people into picking up the phone. This week, the chairman said that he expects major phone providers to implement such standards this year and the FCC will host a summit on July 11, 2019 to review the industry's progress.
Robocalls are a problem for users across devices created by Apple, Google, and others. While there are ways to block a number that's already called you on iOS, robocalls can repeatedly contact you using different numbers and methods, making them all the more difficult to stop.
Over the years, carriers like AT&T and Verizon have also launched their own spam protection apps that aim to warn users when a call is coming in that is likely a robocall. Still, these apps can only do so much and robocall-tracking company YouMail recently estimated that there were 48 billion unwanted calls in the U.S. in 2018, up 60 percent from 2017.
