Abstract
Enhanced services, such as call restriction, call forwarding, anonymous call rejection, and proprietary services, may interfere with an emergency callback potentially preventing the callback from reaching the intended destination. Systems and methods for processing emergency calls to eliminate emergency callback failure in response to an emergency call being disconnected are provided herein.
