Abstract

Computer-implemented methods of placing and processing calls in a communications network are provided. The computer-implemented method of processing calls in a telephone network comprises: identifying a plurality of calls that have been made by a particular telephone number to telephone numbers in the telephone network; determining whether a sequence in which the calls were placed corresponds to a correct order for calling those telephone numbers, the correct order being determined based on a predetermined order for calling telephone numbers in the telephone network; and determining that one or more of the calls were made by spoofing the particular telephone number if the sequence in which the calls were placed does not correspond to a correct order.
