What is E911 and why is it important?

Enhanced 911, E-911 or E911 is a North American telecommunications based system that automatically associates a physical address with the calling party's telephone number, and routes the call to the most appropriate Public Safety Answering Point (PSAP) for that address. The caller's address and information is displayed to the 911 dispatcher.

An E911 compliant system (including SIP E911) provides emergency responders with the location of the emergency without the person calling for help having to provide it. This is often useful in times of fires, break-ins, and other events where communicating one's location is difficult or impossible.

N2Net is E911 compliant and provisions E911 information by DID (Phone Number).
