Apple has released iOS 13, which includes a new feature to combat unwanted robocalls called "Silence Unknown Callers" that sends calls from unrecognized numbers directly to voicemail. This feature may help reduce the annoyance of illegal robocalls but raises concerns about unintended consequences, such as consumers potentially missing important calls. The success of this feature depends on various factors, including how well consumers use it and whether other technologies, like SHAKEN/STIR, are used in conjunction with it to provide a more secure authentication framework. Twilio is working on a program that provides context about why organizations are calling, aiming to improve the user experience and reduce unwanted calls.
