Abstract
The VoIP Management System is capable of identifying voice-based wireless devices and denying wireless communication services to these devices. The VoIP Management System also identifies VoIP packet data traffic, and this communication connection can be denied. The VoIP Management System can also identify encrypted VoIP packet data traffic (for a unique Source -Destination IP pair) based upon VoIP packet data traffic characteristics: packet timing, packet rate, and packet size, since VoIP services have a distinct packet data traffic pattern. When a VoIP call is detected, the VoIP Management System disrupts the identified VoIP packet data traffic, without modifying the packet data content, such as by adding sufficient latency to the Packet Data Unit of the packet data traffic to make the VoIP services unusable.
