ABSTRACT:
A communication system processes a set-up message for a call to transfer a query message to a network call processor that processes the query message to transfer an inquiry message to a remote call processor. The remote call processor processes the inquiry message to select a key and transfers the key to the network call processor. The remote call processor transfers the key and call-handling information for the call to a destination system. The network call processor transfers the key to the communication system. The communication system transfers the key and the call to the destination system. The destination system associates the call with the call-handling information based on the key.
