Abstract

A routing device of a telecommunications network can receive an initiation request of a communication session. The initiation request can include a destination identifier associated with a terminal. The routing device can query a responder for terminal-associated serving-network information. The routing device can then forward the initiation request to a serving network identified by the serving-network information. In some examples, the responder can query a registry for network-attachment information indicating a current media path associated with the terminal. The responder can provide the serving-network information based at least in part on the network-attachment information. In some examples, the destination identifier can include a global name, and the serving-network information can include an associated local name In some examples, the routing device can include an S-CSCF or ISBC, the responder can include an ENUM server, or the registry can include an HSS.
