Design and implementation of interception model in SIP network
SIP网络监听模型的设计与实现

According to the SIP network and its protocol's characteristic, this article placed emphasis on how to implement interception work rapidly and effectively in Session Initiation Protocol (SIP) network. And on such basis, a design of network interception model was put forward as well as the implementation flow aiming at the target UA's communication. Both the design and the implementation above are exploratory. They are not only more flexible but also more convenient than the existing interception interfaces.
