The data table includes a table header for identifying the data table. Data in the table is organized in one or more rows corresponding to one or more columns. The data table further includes a table specification for defining the one or more columns of the data table. Data tables can be created in a telephone service creation environment in the telecommunication network and can be accessed by one or more call processing records for executing telephone services during telephone service execution. The call processing records comprise a plurality of nodes and branches, each node representing a particular call processing procedure. The data tables are stored in a data base in the telephone service creation environment.
