1. A method of detecting revenue leakage in a telecommunications system, the method comprising: detecting, by one or more processors connected with the telecommunications system, one or more characteristics of non-reconciled telephony service detail records for calling line identities across point codes and routes for selected calls on the telecommunication system; associating, by one or more processors connected with the telecommunications system, the detected characteristics with at least one of a plurality of profiles, each of the profiles comprising one or more exponentially-decayed recursive variables that summarize a history of calling behavior; generating an absolute value, frequency and proportion for at least one of the detected characteristics or at least one of the profiles; and generating a hierarchal summarization of the detected characteristics or the at least one of the profiles according to the absolute value, frequency and proportion.
