Abstract: A method of monitoring call center attendants' assistance to callers is provided in which a call monitor is configured to record interaction between attendants and callers. Such interaction may be recorded for all, or substantially all, calls received at a call center. The reviewer optionally specifies criteria concerning calls that are to be recorded. The call monitor connects to a call center switch after a call attendant logs in. When the attendant receives a call matching the specified criteria, if any, the call monitor records interaction the attendant and the caller to create a call record. In a present embodiment of the invention, the call record is stored on the call monitor in compressed digital format. To replay a call record, the reviewer connects to a web server or other interface through an internetwork connection. From the web server the supervisor selects a call record to be played.
