Voice Over IP & 911 Service Advisory
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 Federal Communications Commission (FCC) has taken steps to close this gap by imposing Enhanced 911 (E911) obligations on providers of "interconnected" VoIP servicesthat is, VoIP services that use the Public Switched Telephone Network (PSTN), including wireless networksto 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.
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, in most cases the call is sent to an emergency service provider in your local area. 911 operators can often automatically identify your location and dispatch the closest emergency personnel. Operators can also often identify your telephone number and 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 calls may not connect to a 911 center.
- VoIP 911 calls may ring to the 911 center's administrative line, which may not be staffed after hours.
- VoIP 911 calls may correctly connect to the 911 center but not transmit the user's phone number and/or location.
- 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.
The FCC has imposed the following requirements:
- All interconnected VoIP providers must provide 911 service to customers without customers having to request the 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 where the service will be first used.
- Interconnected VoIP providers must provide an easy method for customers to update the physical location they have registered with the provider.
- 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 customers have a clear understanding of the limitations, if any, of their 911 service.
- All providers must advise new and existing customers of the circumstances under which 911 service may not be available or may be limited in comparison to traditional 911 service.
- All providers must distribute labels to customers warning them that 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 acknowledgement from existing customers that they 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 911 call center.
To ensure your ability to dial 911 you should:
- Provide your accurate physical address to your interconnected VoIP service provider.
- 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.
- Be aware that your VoIP service may not work if your power is out or your Internet connection is down. You might consider installing a backup power supply, maintaining a traditional phone line, or having a wireless phone as a backup.
- Contact your service provider if you have questions about whether the phone service you are receiving is an interconnected VoIP service.
