ABSTRACT:
An E-9-1-1 voice-over-IP (VoIP) solution is provided wherein a 911 call from a wireless VoIP device is routed directly to the correct Public Safety Answer Point (PSAP) via dedicated trunks, together with correct location information and call-back number. VoIP gateways are implemented locally, at least one per LATA, and accept VoIP packetized data inbound, and convert it to standard wireline voice calls. Calls are routed to an IP address at the VoIP gateway, which then egresses the call to a voice port at a selective router. Dedicated voice trunks (CAMA, SS7, FG-D) are installed between each local VoIP gateway and appropriate selective routers. An Automatic Location Identification (ALI) database is provisioned with ESRKs dedicated for VoIP use. TCP/IP circuits may be established between some or all of the various local VoIP gateways.
