  • Emergency call localization for IP-based telephony
    Patent number: 8576990
    Abstract: A method and system for localizing an initial point of an Internet Protocol (IP)-based telephone call that is an emergency call. A Telephony Application Server (TAS)-Proxy receives the emergency call originating from a Voice-over-IP (VoIP) subscriber. An emergency call application transmits to a replication database a request for emergency call data for identifying an initial point of the emergency call. The replication database determines the emergency call data from the IP address of the VoIP and transmits the emergency call data to the emergency call application. The emergency call applications sends the emergency call data to the TAS-Proxy. The TAS-Proxy routes the emergency call, and sends an Emergency ID of the emergency call data, to a local responsible Public Safety Answering Point. The local responsible Public Safety Answering Point can use a reference in the Emergency ID to technical data to locate the initial point of the emergency call.
