In a decision issued in April of this year, the Canadian Radio-television and Telecommunications Commission ("CRTC") required all telecommunications service providers ("TSPs") in Canada to implement STIR/SHAKEN to authentic and validate IP-based calls effective 30 November 2021.
STIR/SHAKEN is a set of protocols and procedures that are intended to reduce caller identification ("ID") spoofing. Caller ID spoofing occurs when callers deliberately falsify (or spoof) their caller ID. This conduct undermines the ability of call recipients to screen out nuisance calls.
