On February 16, 2020, a new federal ruling called Kari's Law comes into effect for enterprises with multi-line telephone systems (MLTS). The law requires the elimination of prefix digits when calling 911 and notification of designated personnel when a 911 call is placed. Additionally, Section 506 of RAY BAUM’s Act has been adopted by the FCC to improve dispatchable location information for first responders. Enterprises should consult with legal teams, plan proactively for employee safety, map user endpoint locations, and test 911 across endpoints to prepare for these new E911 regulations.
