IPC: H04M3/436
Filed: 2019-05-24
Abstract: There is provided a mechanism that allows automated calls (which may be junk, spam, nuisance or unwanted 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 features may comprise variations in call frequency over time including transitions from quiet periods to busy periods (and/or vice versa). The classification indicates whether the calls include automated calls. Further calls from the set of numbers are routed in accordance with the classification, which may involve preventing calls identified as automated from being routed, or routing the call straight to an answer machine.
