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 services, i.e., VoIP services 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.

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.

What should I know about VoIP?

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 an  emergency service provider in your local area. 911 operators can often automatically identify your location and dispatch the closest emergency personnel. They also often can 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:
