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:
To reduce these differences and any possible risks to public safety posed by interconnected VoIP 911 service, the FCC has imposed the following requirements:
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.
