Optimized routing of VOIP emergency calls |
摘要 |
A method for routing emergency calls is provided for emergency calls placed over a packet-switched network ( 310 ) from a Customer Premises Equipment (CPE) ( 110 ) at a remote location ( 100 ). The method includes: registering the CPE ( 110 ) with a home Internet Service Provider (ISP) ( 260 ) through a remote ISP ( 130 ) that is providing the CPE ( 110 ) access to the packet-switched network ( 310 ); determining that the CPE is at a remote location ( 100 ); obtaining a local Internet Protocol (IP) address that corresponds to a Public Safety Answering Point (PSAP) ( 170 ) serving the remote location ( 100 ); routing non-emergency calls to the home ISP ( 260 ) for call processing; and, handling emergency calls locally at the remote ISP ( 130 ) in accordance with the obtained local IP address.
