description The invention discloses a main-standby synchronizing mechanism in SIP (Session Initiation Protocol) firewall software, which relates to a main-standby synchronizing mechanism used by the SIP message firewall. Since multiple main-standby SIP firewalls process message packets of an SIP calling, the same calling generates multiple SIP messages during the calling, the messages can pass through different SIP firewalls, the main-standby firewalls need to uniformly process the SIP messages belonging to the same calling to realize the main-standby synchronization. In order to solve the main-standby synchronizing problem, the operation of multiple SIP firewalls needs to be controlled by a uniform service server, the SIP firewall and the service server determine only one calling by the SIP calling identifier, therefore, for the same calling, the processing of the main-standby firewalls can be consistent to realize synchronization. The main-standby synchronizing mechanism can solve the main-standby synchronizing problem
