Abstract: Phone numbers can be identified as being associated with spam callers. Data associated with previously identified spammer phone numbers is analyzed to obtain one or more input parameters for a classification engine. The classification engine uses the input parameters to identify one or more phone numbers in data associated with currently active phone numbers as being associated with spam callers. The one or more phone numbers identified as being associated with spam callers can be provided to call blockers of end-user telephone devices.
