System and method for call redirect detection and treatment
View Patent ↗Disclosed are systems and methods in which call intelligence, such as may be disposed in communication with signaling systems utilized in controlling calls, is used to provide information for making determinations with respect to the treatment of calls. Call intelligence may be coupled to or disposed within such networks to receive signaling therefrom and/or transmit signaling thereto for determining the appropriate treatment of a call and, preferably, controlling the treatment of a call in accordance with such determination. Signaling messages received by call intelligence may be utilized to determine that a particular calling activity (e.g., enhanced calling service such as call redirecting or three-way calling) is being employed, to collect data with respect to a call, and the like. Signaling messages transmitted by call intelligence of the present invention may be utilized to prevent a call from being setup, to prevent a particular aspect of a call, to provide information to a billing entity for payment, and the like.
