Abstract
This patent concerns a system and method for detecting a mass calling event in a telephone system and to regulate telephone calls to a call destination for which a mass calling event has been detected where a packet transport network and Call Server is integrated into the Public Switched Telephone Network (PSTN). A packet transport network and a central Call Server implement switching functionality traditionally provided by numerous Time Division Multiplexing (TDM) switches within the PSTN. A credit bucket mechanism is used for call regulation in a mass calling event. The packet network may be based on (but is not limited to) ATM, Frame Relay, or IP packet protocols.
