Direct dial, notification, and location
Learn it in 5 minutes
- This page is study material, not legal advice and not an emergency plan.
- The FCC page opened for this lab says Kari's Law requires direct 911 dialing on covered multi-line systems, without a prefix such as 9.
- The same page says notification must not delay the 911 call, and must include that a 911 call was made, a callback number, and the location the system sends, unless that information is technically infeasible.
- Section 506 of RAY BAUM'S Act, as the FCC page describes it, is about dispatchable location: a validated street address plus detail such as a suite or apartment.
- Enhanced 911, in the Wikipedia article opened here, is the North American system that delivers a caller's location to the dispatcher. Other regions use other numbers.

What is going on
The FCC's multi-line telephone system page, opened in 2026-10, says the Commission adopted rules in August 2019 for Kari's Law and Section 506 of RAY BAUM'S Act. Kari's Law and those rules are forward-looking: the page says they apply to systems manufactured, imported, first sold or leased, or installed after February 16, 2020, with a direct-dial and notification date of February 17, 2020 for those systems. Dispatchable location for on-premises fixed devices is dated January 6, 2021 on that page, and on-premises non-fixed plus off-premises devices January 6, 2022, with alternatives when automated dispatchable location is not technically feasible. A lab route pattern is not that configuration. Confirm the rule where the site operates. The congress.gov bill page did not open past a challenge, so this lab does not link it.
Confirm before relying. Confirm the emergency number, the statute, and the carrier outside the FCC page. This lab did not open those texts.
Worked example
A hotel phone that only dials 911 after a 9 will fail the direct-dial idea the FCC page describes, even if a test call with the prefix reaches a dispatcher. The study question is whether a station can dial 911 with no extra digit, and whether a person likely to see or hear a notice is told at the same time. The location string that rides with the call is a separate question.
Quiz
1. Kari's Law, as the FCC page describes it, is satisfied by requiring users to dial 9 before 911.
False. The page says direct dialing means no prefix or access code such as 9.
2. This lab page is legal advice for every country.
False. It is a study note about pages that were opened. Confirm the rule where you operate.
Ecosystem
Sister pieces sit on the ecosystem page: the glossary, the mind map, the integration map, and the sibling labs.
- MLTS — A multi-line telephone system, the term the FCC page uses for enterprise and hotel phone systems.
- Dispatchable location — The FCC page's term for a validated street address plus detail needed to find the caller.
Config. Write the digits a real station dials for emergency, and who is supposed to see the notice. Do not invent a prefix.
Troubleshooting. If the only successful test used an access code, you have not tested direct dial.
Bridge. CUCM can route 911, but routing is not the same as location. Cisco Emergency Responder is the location product in the next room.
