ABSTRACT:
A system and method for processing a plurality of call detail records (CDRs) each indicative of a call transaction on a telecommunications network. The method includes receiving the plurality of CDRs at a first controller, wherein each of the CDRs include a data structure including a plurality of fields each containing at least one character. The method then selects a first sorting field from the plurality of fields and groups the plurality of CDRs as a function of data within the first sorting field. In one embodiment, the first sorting field is used to group the CDRs according to different carriers. The method then analyzes at least one additional sorting field within each of the CDRs which were previously grouped according to the first sorting field. A report is then generated for each of the grouped CDRs as a function of data within the additional sorting field. In this way, periodic, customized reports can be generated from information contained with CDRs with user-selectable sorting or analysis fields.
