Attorney, Agent or FirmInternational ClassH04M 003/42AbstractA system for an international telephone redial service is provided for callers who attempt to complete telephone calls to parties via foreign telephone networks. If a call is not completed, the foreign network returns unsuccessful call reason information related to the cause of the call completion failure. Informative messages may be played to the caller to inform the caller of the nature of a given call failure. Unsuccessful call reason information may be organized in groups, so that each group of unsuccessful call reason information is associated with a different informative message. International redial service may be selectively based on unsuccessful call reason information. International redial service may be inhibited when the cause of a call completion failure is due to a semi-permanent condition, such as when a non-existent number is dialed. | |
