ABSTRACT:
A call schedule is received that includes a plurality of sample calls to be made by an automated calling station. The plurality of sample calls are automatically placed on the network using the automated calling station. At least one final billing record corresponding to the at least one completed sample call is received. The call data is processed to determine billed cost data. The billed cost data is compared to the previous cost data and a change in the rate plan is detected based on the comparison of the billed cost data to the previous cost data.
