Abstract
The invention provides a system, method and apparatus for controlling a mass calling event in a VoIP network. The invention provides for monitoring port traffic information on a network edge device and detecting the occurrence of a mass calling event in conjunction with a call control module. Control instructions or information may then be provisioned to network edge devices to alleviate congestion. The invention enables network edge devices to gap or provide other controls to reduce call overloading. Controls for alleviating congestion include blocking the packets, providing an announcement to the call, re-routing the traffic associated with this specific mass calling event, and reducing the quality of the service.
