【摘要】 在基于SIP(SessionInitiationProtocol)协议的VoIP网关的分析研究基础上,为提供VoIP网关模块中各用户代理的状态监控和话务管理,针对各种特殊的话务请求,定义了如强拆、强插、监听等私有的管理对象,实现了对核心信令模块行为的控制和有效的管理,同时也为SIP协议呼叫控制的管理信息库的标准化提供了参考。更多还原

【Abstract】 This paper studies a SIP-based VoIP gateway. In order to watch states and manage calls of each user agent,aiming at various especial calls,the paper defines several private management objects such as break,intervening and monitor. In this way,it controls and manages the actions of the core modules. This implementation already provides references to the standardization of MIBs of call control based on SIP.更多还原
