ABSTRACT:
A method and system for forwarding information, such as a message waiting indicator (MWI) message, to a telephone number corresponding to a foreign network (e.g., a wireless network) and a shared NPA/NXX. The invention evaluates individual telephone numbers of shared NPA/NXXs to determine to what networks to send messages. A representative embodiment of the invention uses a service control point and service package application to deliver an MWI message from a messaging service provider to a wireless (i.e., foreign network) telephone number of a shared NPA/NXX. Shared NPA/NXXs are marked as “portable” in a signal transfer point for forwarding to the service control point, which determines whether the shared NPA/NXX telephone numbers require local number portability global title translation or should be forwarded to an inter-switch voicemail routing (ISVMR) service package application. The ISVMR service package application determines the point code to which the MWI message should be routed.
