Abstract:
A method and apparatus for enabling a signaling message to be sent in response to an emergency call, e.g., an E911 call, set up message to provide information as to whether or not the E911 call has been successfully completed are disclosed. An indicator of a failed call setup will trigger the call to be re-originated transparently to an emergency center where live operators can handle the call on a 24hours/day basis. In one embodiment, an emergency center is a call center that is operated by a network provider or a third party provider to support emergency calls when a PSAP cannot be reached by a caller for various reasons. The emergency center is capable forwarding a call to the appropriate PSAP for call termination on behalf of the E911 caller.
