CALL PROCESSING DIGIT TRANSLATION AND CHARACTERIZATION

摘要

An optimal digit translation and call processing system and method is provided. A prefix translation and digit characterization process are performed utilizing a digit prefix table and a second table of call termination types. The digit prefix table contains records corresponding to prefixes of dialed digit streams. Each record includes an index to a record of the second table. A dialed digit stream length is analyzed to resolve ambiguities in the digit stream when an index in a record of the digit prefix table references more than one record of the second table. A call screening table is interrogated with termination type data obtained from the second table. The call screening table can pass call control to a national or international translator table which provides a route index. The route index may be modified by data in additional tables before the call is ultimately routed.
