Abstract
Aspects of the disclosure relate to routing of an emergency communication under fault conditions. Routing can be implemented in a packet-switching (PS) network that provides voice service. For a network node of the PS network, availability to route the emergency communication through a specific emergency service routing number (ESRN) can be determined and, in response to the network node being unavailable, administrative data associated with the ESRN can be accessed. In addition, an identifier associated with the administrative data can be updated (e.g., created or modified) with data indicative of the device that originated the emergency communication. The administrative data and the resulting identifier can be delivered to a second network node that can route the emergency communication to an emergency service network.
