Abstract: A proxy-server system (15) connected preferably to a computer-telephone system (10) intercepts, processes, and analyzes as traffic-analysis results (68A-C) all forms of real- and non-real-time electronic communication passing over the network in the form of raw traffic data (61). The proxy-server system normalizes each communication into the measure of time needed by recipient(s) of the communication to understand the information contained therein. Once normalized, the data may be aggregated into summary reports (69A-C). As part of the analysis, the aggregated communication records are compared with user-defined rules to provide alerts if the individual or aggregated durations exceed boundaries set by the rules. In one embodiment, the summary reports may be integrated with general-ledger data (94) and other raw business data (74) via a relational database (72) to derive more accurate records of activity-based-costing information (76).
