The detection capability of the Avaya SBC solution uses numerous dynamic and adaptive algorithms to detect any anomalies in the learned caller behavior that are based upon user-definable Time-of-Day (ToD) and Day-of-Week (DoW) criteria. These algorithms are flexible enough to accommodate special circumstances such as weekends, holidays, and other user-specified time periods. Avaya SBC solution can also learn and apply dynamic trust scores, starting from an unknown score and either increasing or decreasing to different levels depending upon the behavior pattern of the caller, which could be Trusted, Known, Unknown, Suspected, or Spammer. The dynamic trust score is also dependant upon called party feedback, including (Black List and White List, further enhancing the time-critical ability to detect anomalous behavior.
