Abstract
The present invention is a call routing system for use in directory assistance. The call routing system employs a primary call routing device configured to receive directory assistance calls from callers at a first directory assistance system, and determines, for each of the calls, whether they will be handled by the first directory assistance system, or by a second directory assistance system among a plurality of directory assistance systems.A secondary router is also provided, configured to route the calls within the first directory assistance system to the primary call routing device. The secondary router has a default call distribution logic, such that if the primary call routing device is off-line, the secondary call router routes the calls among the first directory assistance system and the plurality of directory assistance systems according to the default distribution logic.
