For a covered system, Kari’s Law concerns direct 911 dialing and on-site notification, and the RAY BAUM’S Act rules concern the location sent with the call. An emergency calling project has to prove three separate things: the caller reaches 911 with no access code, the 911 center receives a usable location, and the right people on site are notified.

This paper explains which systems and devices the federal rules cover, what each control should look like in a written requirement, and how to test and record the result for every phone and route. It also covers keeping locations current after a phone moves.
