Federal E911 rules
Kari's Law and RAY BAUM's Act explained for phone-system owners
These rules made emergency calling a board-level safety and compliance topic for organizations that operate enterprise, business phone system, internet-based voice, and cloud calling environments.

Kari's Law
Direct 911 dialing
Covered systems must let users reach 911 without dialing a prefix, access code, or operator first.
Notification
On-site awareness
Internal notification helps security or reception teams respond when an emergency call is placed.
RAY BAUM
Dispatchable location
Emergency calls need location information detailed enough to help responders find the caller.
What Kari's Law changed
Kari's Law addressed a simple but dangerous problem: people in hotels, offices, campuses, and other business phone system environments sometimes had to dial an outside-line prefix before 911. In a crisis, that extra step can cost time.
The practical lesson is straightforward: emergency calling must work the way ordinary people expect. Pick up the phone, dial 911, and get help.
- No outside-line prefix for 911.
- No operator or front-desk intervention before reaching emergency services.
- Notification to appropriate on-site personnel when technically feasible and applicable.
- Coverage review for hotels, offices, schools, healthcare facilities, warehouses, and multi-tenant environments.
What RAY BAUM's Act changed
RAY BAUM's Act pushed the industry toward dispatchable location. A 911 answering center needs to know not only the account or billing address, but where responders should go.
For internet-based voice and cloud phone systems, this means location is no longer a static spreadsheet attached to phone numbers. It is a lifecycle process.
- Validated civic address.
- Additional detail such as floor, suite, room, zone, or building where needed.
- Support for fixed, nomadic, and remote users.
- Policies for softphones, mobile apps, shared phones, and common-area devices.
How to show good-faith compliance
A defensible E911 program produces evidence. If a call fails, leadership will need to know what was configured, what was tested, what changed, and who owned remediation.
- Maintain an inventory of covered systems and locations.
- Document direct-dial testing.
- Document delivered callback and location results.
- Review notification delivery and escalation paths.
- Keep change-control records for carriers, SIP voice trunks, session border controllers, UC policies, and network location assignments.
