The FCC has issued some regulations regarding VoIP and the ability to call 911. Because VoIP uses the Internet and not a landline phone, when a call is made to 911 from a VoIP connection, the operator who receives the call receives none of the caller's pertinent information. This includes address or location of the call. Some service providers do not supply 911 at all; others have what is known as Enhanced 911 services. To use these services you may need to activate your service, as well as register your information with 911. However, you will need to sign a statement when you apply for your VoIP services stating that you understand your 911 capabilities may be limited.
