The ability to access emergency services by dialing 911 is a vital component of public safety and emergency preparedness. Recent reports of consumers’ inability to access life-saving emergency services while using Voice over Internet Protocol (VoIP) services have highlighted a critical public safety gap. The FCC has taken steps to close this gap by imposing Enhanced 911 (E911) obligations on providers of "interconnected" VoIP services. Interconnected VoIP services are those that use the Public Switched Telephone Network (PSTN), including wireless networks, to originate and terminate calls. E911 systems automatically provide to emergency service personnel a 911 caller’s call back number and, in most cases, location information.
In May 2005, the FCC adopted rules requiring providers of interconnected VoIP services to supply 911 emergency calling capabilities to their customers as a mandatory feature of the service by November 28, 2005. "Interconnected" VoIP services are VoIP services that allow a user generally to receive calls from and make calls to the traditional telephone network. Under the FCC rules, interconnected VoIP providers must:
- Deliver all 911 calls to the local emergency call center;
- Deliver the customer’s call back number and location information where the emergency call center is capable of receiving it; and
- Inform their customers of the capabilities and limitations of their VoIP 911 service.
The Public Safety Challenges of VoIP Services
Traditional phone services have generally associated a particular phone number with a fixed address. Portable interconnected VoIP services enable consumers to take their home or business phone service almost anywhere. Because certain interconnected VoIP services can be used from virtually any Internet connection, the location of the caller cannot automatically be determined.
This portability raises a number of challenges for the emergency services community. The FCC has recently taken action to make sure that emergency calls from these VoIP services will get through to the appropriate public safety authorities, but there are certain things that consumers need to know.
When you call 911 from a traditional telephone, the call in most cases is sent to a Public Safety Answering Point (PSAP) that is responsible for helping people in a particular geographic area or community. PSAP personnel often can automatically identify your location and direct the closest emergency personnel to that location. They also often can automatically identify your telephone number so that they can call you back if you are disconnected.
Because VoIP service works differently from traditional phone service, consumers who use it should be aware that VoIP 911 service may also work differently from traditional 911 service. The FCC and VoIP service providers are striving to eliminate these differences, but some of them are:
- VoIP 911 call may not connect to PSAP;
- VoIP 911 service may ring to the administrative line of the PSAP, which may not be staffed after hours, or by trained 911 operators;
- VoIP 911 service correctly connected to the PSAP, but did not automatically transmit the user’s phone number and/or location information;
- VoIP customers may need to provide location or other information to their VoIP providers, and update this information if they change locations, for their VoIP 911 service to function properly;
- VoIP service may not work during a power outage, or when the Internet connection fails or becomes overloaded.
To reduce these differences and any possible risks to public safety posed by interconnected VoIP 911 service, the FCC has imposed the following requirements:
- All interconnected VoIP providers must automatically provide 911 service to all their customers as a standard, mandatory feature without customers having to request this service. VoIP providers may not allow their customers to “opt-out” of 911 service.
- Before an interconnected VoIP provider can activate a new customer’s service, the provider must obtain from the customer the physical location at which the service will first be used, so that emergency services personnel will be able to locate any customer dialing 911. Interconnected VoIP providers must also provide one or more easy ways for their customers to update the physical location they have registered with the provider, if it changes.
- Interconnected VoIP providers must transmit all 911 calls, as well as a callback number and the caller’s registered physical location, to the appropriate emergency services call center or local emergency authority.
Interconnected VoIP providers must take appropriate action to ensure that their customers have a clear understanding of the limitations, if any, of their 911 service. All providers must specifically advise new and existing customers, prominently and in plain language, of the circumstances under which 911 service may not be available through the interconnected VoIP service or may be limited in comparison to traditional 911 service. They must distribute labels to all customers warning them if 911 service may be limited or not available and instructing them to place the labels on and/or near the equipment used in conjunction with the interconnected VoIP service.
- Interconnected VoIP providers must obtain affirmative acknowledgement from all existing customers that they are aware of and understand the limitations of their 911 service.
- In some areas, emergency service providers are not capable of receiving or processing the location information or call back number that is automatically transmitted with 911 calls. In those areas, interconnected VoIP providers must ensure that a 911 call is routed to the appropriate PSAP.
The Federal/State Task Force
Access to 911 emergency services is an issue that affects us at all levels - national, state, and local. Therefore, the FCC and the National Association of Regulatory Utility Commissioners ("NARUC") formed the Joint Federal/State VoIP Enhanced 911 Enforcement Task Force to facilitate compliance with and enforcement of the FCC's VoIP 911 rules. The Task Force, which consists of staff from the FCC and State Public Utility Commissions, will coordinate closely with the National Emergency Number Association, the Association of Public Safety Communications Officials, and state and local 911 authorities. The Task Force's mission is to develop educational materials to ensure that consumers understand their rights and the requirements of the FCC's VoIP 911 Order; develop appropriate compliance and enforcement strategies; compile data; and share best practices.
Tips for VoIP Subscribers
If you have or are thinking of subscribing to an interconnected VoIP service, you should:
- Provide your accurate physical address to your interconnected VoIP service provider to ensure that emergency services can quickly be dispatched to your location.
- Be familiar with your VoIP service provider’s procedures for updating your address, and promptly update address information in the event of a change.
- Have a clear understanding of any limitations of your 911 service.
- Inform children, babysitters, and visitors about your VoIP service and its 911 limitations, if any.
- If your power is out or your Internet connection is down, be aware that your VoIP service may not work. Consider installing a backup power supply, maintaining a traditional phone line, or having a wireless phone as a backup.
- If you have questions about whether the phone service you are receiving is an interconnected VoIP service, contact your service provider for further information.
