Patent ID: 7992205

Claim:
A method comprising: receiving, from one or more receiving devices, multiple user reports that identify call connections established between a call source and the one or more receiving devices as spam calls, wherein the multiple user reports are based on a perception by at least one user of the one or more receiving devices that the call connections established between the call source and the one or more receiving devices are spam calls, and wherein information corresponding to the call source is stored in a storage repository responsive to receiving a first one of the multiple user reports; after receiving the multiple user reports that the call source established multiple spam calls, updating the information corresponding to the call source in the storage repository to designate the call source as a repeat spam call offender; initiating, with a call control center, monitoring of any future call connections the call source designated as the repeat spam call offender attempts to establish in response to updating the information corresponding to the call source in the storage repository to designate the call source as the repeat spam call offender; and re-updating the information corresponding to the call source in the storage repository to re-designate the repeat spam call offender as a confirmed repeat spam call offender after the call source designated as the repeat spam call offender has been monitored attempting to establish at least one future call connection having at least one spam call characteristic, and wherein the re-designation of the call source as the confirmed repeat spam call offender indicates that one or more new call connections initiated by the call source are to be blocked for all receiving devices.
