Abstract
A computer system receives a first message from an originating communication node indicating a telephone number for a user. The computer system processes the telephone number, number portability data, and user mobility data to identify a first route number for a home communication node and a second route number for a visited communication node currently serving the user. The computer system transfers a second message to the originating communication node indicating the first route number and the second route number. The call may be routed from the originating communication node to the visited communication node based on the second route number, but if the visited communication node is unable to complete the call, the call may be routed from the originating communication node to the home communication node based on the first route number.
