Estimating the term…
An IP Telephony Emergency Connections (ITEC) system and method that determines the precise origin of an emergency call and routes the call to the proper Public Service Answering Point (PSAP). A source-based routing mechanism is provided in an IP telephony type network, such as a VoIP or IP over LAN/ATM. Emergency calls are routed to the correct PSAP jurisdiction. Each server/switch may include the mechanism such that the IP Telephony network can identify an E911 connection and egress to a public network at a point closest to the emergency call point of origin. Whenever an emergency number call is made, the call's origin is determined during call setup establishment. Every port or end user jack in the network is assigned a Source Group Index (SGI), which is a number or index representing each PSAP jurisdiction in the network. All ports/jacks within the same PSAP jurisdiction are assigned the same SGI. Users may be in different areas of multiple PSAP jurisdictions.
