Abstract
A method, system and apparatus for providing emergency service location of an IP telephony client. A request for an emergency call is received from the IP telephony client. Subsequently, it is determined whether an actual location of the IP telephony client is encompassed by a first location data stored at a corresponding Automatic Location Identification (ALI) database that associates a unique identifier of the IP telephony client with the first location data. The unique identifier is sent for receipt by a Public Safety Answering Point (PSAP) associated with the ALI database, if the actual location is encompassed by the first location data. An Emergency Location Information Number (ELIN) is sent for receipt by the PSAP if the actual location is not encompassed by the first location data, wherein the ELIN is associated with the actual location at the ALI database.
