Today T-Mobile launched a call protection feature called STIR/SHAKEN in partnership with Comcast to prevent robocalls. It’s available on T-Mobile and Metro on certain phones, and could come to iPhones. (via Reuters).
This is T-Mobile’s technology called Secure Telephony Identity Revisited (STIR) and Secure Handling of Asserted information using toKENs (SHAKEN). It’s a way to identify authentic calls across cellular networks.
Right now, certain phones from LG and Samsung have the feature. In the future it will also be available for Comcast Xfinity Voice home phone service customers. T-Mobile hasn’t officially confirmed that its ‘Caller Verified’ feature will come to iPhones, but it’s a possibility and T-Mobile is working with Apple on it.
Robocalls and spam calls are an industry-wide problem, and we’ve got to join forces to keep consumers protected. Today, we’re the first to cross industry lines to do just that.John Legere, T-Mobile CEO
Last month AT&T had announced it successfully tested what it believed was the first STIR/SHAKEN-authenticated call between two different telecom networks with Comcast.
