US Patent 7412260 Routing call failures in a location-based services system

A method and system for routing call failures in a location-based services system. A remote terminal is connected to a location-based services system and is used to generate a voice-based tailored request for information. The voice-based tailored request for information is interpreted with a voice recognition application and a natural language processing application. If the voice recognition application or the natural language processing application fail to determine the meaning of the tailored request for information to a predetermined level of accuracy then the remote terminal is routed to a call center.
