STIR/SHAKEN tech to identify spoofed calls officially kicks in today Nov 30
"As of today, telecommunications service providers will certify whether a caller’s identity can be trusted by verifying the caller ID information for Internet Protocol-based voice calls. This new technology will help reduce the frequency and impact of caller ID spoofing. As service providers continue to upgrade their IP networks and offer compatible phones to their customers, more and more Canadians will be able to see the effects of STIR/SHAKEN."
