Enhanced E911 network access for call centers
First Claim
1. A method of providing a telematics call center with access to an Enhanced 911 network supporting a public safety answering point (PSAP), comprising:
- receiving a non-packetized phone call from a telematics call center;
converting said non-packetized phone call into an Internet Protocol (IP) based packetized phone call;
querying a VoIP positioning center for call routing information to route said IP based packetized phone call to a particular PSAP, said VoIP positioning center query comprising a phone number of a wireless device initiating said non-packetized phone call;
receiving said call routing information from said VoIP positioning center; and
forwarding said IP based packetized phone call both to said particular PSAP based on said call routing information, and to said telematics call center.

Abstract
An emergency call (e.g., a 911 call, an alarm company call) forwarded by a telematics call center is routed over the switched PSTN to a Voice Over Internet Protocol (VoIP) call server, where the switched call is converted to a session initiating protocol (SIP) packetized IP call for presentation to an emergency services gateway, which reconverts the call to TDM and connects to a selective router via dedicated circuits, gaining full access to the Enhanced 911 network. This provides a PSAP receiving a call from a telematics call center or other call center with all features available in an Enhanced 911 network, e.g., callback number of the 911 caller, and location of the 911 caller. Location of the caller is provided using a VoIP positioning center (VPC).
