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