Abstract
A network element for routing a calling name (CNAM) query message through a communications network includes a communication module capable of receiving a CNAM query message from and transmitting the CNAM query message to a communications network. A CNAM query routing information database stores CNAM query routing information for at least one CNAM database. A CNAM query routing address translation process performs a lookup in the CNAM query routing information database based on information contained in the query message and determines whether to route the query message to a national CNAM database based on results from the database lookup.
