Abstract
A method is provided for routing an emergency call from Customer Premises Equipment (CPE) to a Public Safety Answering Point (PSAP). The method includes: establishing a session over a packet-switched network () between a CPE () and a network node (), such that the CPE () accesses a Public Switched Telephone Network (PSTN) () from the network node () via a telecommunications switch () associated with a first PSAP () serving a geographic region () different than where the CPE () is currently located; identifying a telephone number for a second PSAP () serving the geographic region () in which the CPE () is located; and, substituting the identified telephone number for a dialed telephone number when the dialed telephone number is indicative of an emergency call.
