In 2023, a woman in an office building called 911 from her VoIP desk phone during a medical emergency. The call connected. Dispatchers were sent. They went to the company's old address — the one from before they moved offices 8 months ago. The ambulance arrived 14 minutes late to the correct location.
The employee survived. The company was sued. They settled for $380,000.
This is not an isolated incident. E911 misconfiguration on VoIP systems is one of the most common compliance failures I encounter — and one of the most dangerous.
How 911 Works Differently on VoIP
| System | How 911 Finds You |
|---|---|
| Landline | Phone company database (ALI) maps your phone number to your physical address automatically |
| Cell phone | GPS + cell tower triangulation sends coordinates in real-time |
| VoIP desk phone | Whatever address was manually entered when the system was set up |
| VoIP softphone | Whatever address was manually entered — could be wrong if user is remote |
| VoIP mobile app | Depends on provider — may use GPS, may use registered address |
The critical difference: landlines and cell phones locate you automatically. VoIP does not. Someone has to manually enter and maintain the correct address for every VoIP endpoint.
The Legal Requirements You Are Probably Violating
Kari's Law (Effective February 2020)
| Requirement | What It Means | Common Violation |
|---|---|---|
| Direct 911 dialing | User dials 911, call connects. No prefix. | System requires dialing 9+911 |
| On-site notification | Someone at the location is notified when 911 is called | Nobody configured the notification |
| Applies to | All multi-line phone systems (including VoIP) | Companies think it only applies to hotels |
Penalty: FCC can fine up to $10,000 per violation, per day.
RAY BAUM's Act (Effective January 2022)
| Requirement | What It Means | Common Violation |
|---|---|---|
| Dispatchable location | 911 call must include floor, suite, or room number | Only building address registered, no floor/suite |
| Applies to | All VoIP and multi-line telephone systems | Companies registered main address only |
| Remote workers | Home address must be registered for each remote user | Remote workers never registered their home address |
This one is critical for remote/hybrid workforces. If your employee calls 911 from their home office, and the VoIP system sends your corporate HQ address, dispatchers go to the wrong location.
The 5 Most Common E911 Failures
| # | Failure | How Often I See It |
|---|---|---|
| 1 | Address never updated after office move | 40% of companies |
| 2 | Remote workers not registered with home address | 70% of companies with remote workers |
| 3 | 9+911 required (Kari's Law violation) | 25% of companies |
| 4 | No on-site notification configured | 60% of companies |
| 5 | Multi-floor building with only one address registered | 35% of companies |
I am not exaggerating these numbers. I audit VoIP E911 compliance as part of every deployment assessment. The majority of businesses are non-compliant.
How to Fix It Today
Step 1: Verify Your Registered Address (5 minutes)
Log into your VoIP admin portal. Check the E911 address for every location. Is it current? Does it include suite/floor number?
Step 2: Register Remote Workers (15 minutes per worker)
For every employee using a VoIP softphone or mobile app from home, register their home address in the E911 system. Most providers have a self-service portal where users can update their own address.
Step 3: Test 911 Routing (Coordinate with PSAP)
Call your local PSAP's non-emergency number. Tell them you want to test E911 from your VoIP system. They will tell you when to call 911 and verify the correct address displays.
Step 4: Remove 9+911 Dialing
If your system requires dialing 9 for an outside line, 911 must still work without the 9. Test it: pick up a VoIP phone and dial 911. Does it connect? If not, fix your dial plan.
Step 5: Configure Notification
Set up email/SMS alerts to your security desk or office manager when 911 is dialed from any extension. Include the caller's name, extension, and registered location.
