Abstract

There is provided a mechanism that allows automated calls made from a set of one or more numbers to be detected and routed in an appropriate manner. The calls are classified based, at least in part, on one or more features of a call frequency time series that is generated from data representing a plurality of calls previously made from a set of one or more numbers by determining a respective number of calls made by the set of numbers during each of a plurality of time intervals. The classification indicates whether the calls include automated calls. Further calls from the set of numbers are routed in accordance with the classification.
