ABSTRACT:
A system (100) for tracking incoming telephone calls includes a first caller identification decoder (166) that decodes caller identification data for a first incoming telephone call including a time stamp having a value reflecting a first time. The system (100) also includes a database (170) for storing the value of the time stamp, a second caller identification decoder (164) that decodes caller identification data relating to a second incoming telephone call initiated at a second time and a frequency counter (156) having a first value at the first time and a second value at the second time. A central processing unit (152) is operable to retrieve the value of the time stamp, identify the first and second values of the frequency counter and thereby determine the second time. A database (170) stores a record reflecting the second time for the second incoming telephone call.
