Abstract
Systems and methods are presented for routing 911 or other emergency calls from VoIP terminal equipment, wherein the terminal includes GPS or other means to obtain geographic location information for the current location when a 911 call is initiated, and the terminal includes the geographic location information in a call setup request message to the service provider. Routing logic receives the set request and uses the geographic information to search one or more databases to identify the proper emergency service center to which the call is routed, and also the street address corresponding to the caller'"'"'s current location. The emergency call is then routed to the selected service center, where the call may be delivered with the street address or the street address information is updated in an ALI database of the 911 system by the routing logic before or during call delivery to ensure the emergency service operator or dispatcher knows where to direct emergency services.
