Apple is taking a new step to combat spam calls in iOS 13. Today, you can already install third-party spam call screeners on your iPhone, but if that’s not good enough (or something you don’t want to do), iOS 13 will add a new solution this fall. From a report: iOS 13 will be able to automatically silence any calls coming in from an unknown number. Even better, it’ll automatically send them to voicemail. The new “silence unknown callers” option can be toggled on or off based on your preference, but I’m thinking most people will enable it right after updating and leave it that way. The feature is explained on this page of what’s new in iOS 13. So many of the spam calls we’re bombarded with on a daily basis are spoofed to look like a local number. But Apple says that iOS 13 will “use Siri intelligence to allow calls to ring your phone from numbers in Contacts, Mail, and Messages.” Any number that can’t be found in one of those places will be routed to voicemail.
