Abstract
An apparatus for routing in a network environment, is provided that includes an application manager residing in a home network and being operable to interface with an access terminal that makes an emergency call. When the call is placed, a call establishment message is transmitted and is marked as an emergency call, the home network recognizing an identity of a visited network emergency services application server that resides in a visited network. If the access terminal cannot reach the home network at the time the emergency call is made, the access terminal can make the emergency call directly through the visited network emergency services application server. In more particular embodiments, the home network knows the identity through configuration or through dynamic means. Alternatively, the home network knows the identity through a registration mechanism via the access terminal.
