The invention includes a technique for integrating emergency calling for VoIP users with legacy emergency services to facilitate adapting to the evolving emergency services network and the services that are available in a given location. Generic location information provided by (or determined for) VoIP emergency callers, typically in civic or geodetic formats, is translated into Emergency Response Locations (ERLs) defining an area, such as an area within an enterprise premises, in which the caller is located. The translated location information is conveyed to the Public Safety Answering Point (PSAP) with the emergency call in for form of the ANI (Automatic Number Identification) or calling line identification number. An appropriate route/gateway is then selected to be used to reach the PSAP appropriate for the caller's location, and an emergency call notification to the appropriate local emergency response personnel is generated within the enterprise based on the caller's location.

Adaption of emergency calls to the emergency services network based on caller location

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.
