The technical scheme includes a signaling management system and method. The system includes: a core management module used for receiving and distributing signaling, establishing and interrupting communication and managing other modules; a query module which is used for accessing the database to query the signaling information and sending a query result to the core management module; a database which is used for storing the collected signaling information; and a management module which is used for sending a disconnection request to an initiator and a receiver of the signaling according to the signaling information sent by the query module and executing a disconnection operation. The beneficial effects of the invention are that the system and method can effectively reduce operator cutover and configuration tasks, reduce the difficulty of unified management and fault elimination, and have a full-amount telephone traffic accurate management capability. In some special application occasions, the method and ssytem have the advantages of low cost, few fault points, stability, reliability and the like, are a competitive solution for management of harmful telephones after IMS (IP MultimediaSubsystem) conversion of telecommunication networks in special occasions such as armies, and do not have the problems of line cutover or iFC configuration and the like.
