If your business runs a multi-line telephone system, two federal laws shape how 911 has to work on it. Kari's Law (47 U.S.C. 1401) requires that a multi-line telephone system allow a caller to dial 911 directly, without a prefix or access code such as dialing 9 first, and that the system send a notification to a designated on-site location, such as a front desk or security, when a 911 call is placed, where the system is capable of doing so without improvement. The RAY BAUM'S Act (Section 506) requires that a dispatchable location, meaning the street address plus the specific location such as suite, floor, or room where appropriate, be conveyed with 911 calls, including from multi-line telephone systems and certain fixed and non-fixed VoIP and other services.
These rules apply based on the type of phone system you operate, an MLTS, not the type of business you run. They reach offices, medical and dental practices, schools, hotels, retail, warehouses, law firms, and almost any business with a multi-line, PBX, or hosted phone platform. Cyber One Solutions deploys and supports business phone systems such as 3CX and Microsoft Teams Phone, and configures and tests direct 911 dialing, notification, and dispatchable-location settings on the systems it manages.
These are the practical elements a compliant business phone deployment addresses under Kari's Law and the RAY BAUM'S Act. Each one is paired with the configuration, testing, and documentation work Cyber One Solutions performs on the systems it manages. Cyber One Solutions is a technology management firm, not a telephone service provider or carrier, and does not provide 911 service itself.
Kari's Law requires a multi-line telephone system to let users dial 911 directly, without first dialing 9 or any other access code. We configure the dial plan on the systems we manage so 911 connects on the first attempt from every extension.
Kari's Law requires a notification, such as an on-screen alert, email, or message, to a front desk, security, or similar location when a 911 call is placed, where the system is capable without improvement. We set up and test that notification so the right people know a call went out.
The RAY BAUM'S Act requires a dispatchable location, the street address plus specific location such as suite, floor, or room where appropriate, to be conveyed with 911 calls. We map location data to phones, DIDs, and sites on the systems we manage.
Location data is only useful if it stays current. As phones are added, moved, or reassigned, we update the associated dispatchable-location records through your moves, adds, and changes process so a 911 call reflects where the phone actually is.
A configuration is not proven until it is tested. We test direct 911 dialing, notification delivery, and location handling at each location, coordinating so testing validates the setup without disrupting normal service, and confirm results rather than assuming them.
We document how direct dialing, notification, and dispatchable location are configured on the systems we manage, along with test results, so you have a clear record of the work and a reference point when locations or staff change.
Kari's Law and the RAY BAUM'S Act apply because you operate a multi-line telephone system, not because you are in a particular line of work. That is why they reach offices, medical and dental practices, schools, hotels, retail, warehouses, law firms, and nearly any business running a multi-line, PBX, or hosted phone platform. If someone in your building dials 911, the call needs to connect directly and carry a location that emergency responders can act on.
The obligations attach to the type of system, the MLTS, rather than the type of business. A dental office, a warehouse, a law firm, and a hotel are treated the same way if each runs a multi-line or hosted phone platform.
That is why a business with no other federal compliance obligations can still be squarely inside Kari's Law and the RAY BAUM'S Act simply because of the phone system it uses every day.
The RAY BAUM'S Act contemplates a dispatchable location for calls placed from a multi-line telephone system and certain fixed and non-fixed services, which includes softphone and remote users. A teleworker on a laptop or mobile app can place a 911 call from an address that is not your main office.
On the systems we manage, such as 3CX and Microsoft Teams Phone, we configure how location is captured or confirmed for remote and softphone users so a 911 call reflects where the person actually is. Because remote users move, keeping that information current is part of your ongoing moves, adds, and changes process, and customers remain responsible for the accuracy of the location records they provide for remote workers.
Emergency calling depends on the dial plan, the phone system configuration, the network, and the 911 or telecom service provider all working together. Testing is how you confirm the pieces line up before a real emergency does it for you.
We coordinate testing of direct 911 dialing, notification, and location handling at each location so the work validates the configuration without interrupting normal calling, and we document the results as part of the record for the systems we manage.
Cyber One Solutions is a technology management firm. It deploys and supports business phone systems and configures and tests E911, direct 911 dialing, notification, and dispatchable-location settings on the systems it manages. It is not a telephone service provider or carrier, does not provide dial tone or 911 service, and does not guarantee regulatory compliance.
Ultimate regulatory compliance responsibility for Kari's Law and the RAY BAUM'S Act rests with the customer and its telecommunications and 911 service provider. Emergency calling depends on proper configuration of your carrier account, network, and endpoints, and on accurate, up-to-date location records that the customer is responsible for maintaining for every physical location and remote user. Customers with questions about their regulatory obligations, 911 service, or carrier compliance should contact their 911 or telecommunications provider or qualified telecommunications counsel.
Common questions from businesses working out how Kari's Law and the RAY BAUM'S Act apply to their phone system and what Cyber One Solutions configures and tests on the systems it manages.
