SIP协议是一个用于建立、更改和终止多媒体会话的应用层控制协议。它是IETF多媒体数据和控制体系结构的一部分，并借鉴了许多已有的Internet协议，具有简单、便于扩展和扩充等特点。文中描述的系统，由于此平台开发较早，不支持标准的SIP协议通讯，鉴于现实需求又必须要对外提供标准SIP协议接口，如果对系统进行改造将会是颠覆性的重构。所以文中通过对SIP协议栈的解析，针对已有的非SIP域设计了一种通讯策略，实现了标准SIP域和非SIP域之间的通讯，使得SIP协议兼容现有的视频调度系统，提高了使用范围，避免非SIP域的重新设计，并得到了较好应用。

SIP is an application layer control protocol for creating,modifying and terminating multimedia sessions. It is the part of IETF multimedia data and control system architecture,drawing on many existing Internet protocols,has the features such as the simple,easy to extend and expand. The system described in this paper,since the early development of this platform does not support standard SIP com-munication,in view of the practical needs also must provide external standard SIP interface,if the system is changed would be disruptive reconfiguration. So through the SIP stack analysis,design a communication strategy for present non-SIP domain,achieving the communi-cation between standard SIP domain and the non-SIP domain,making the SIP compatible with existing video scheduling system,impro-ving the scope of use,to avoid non-SIP domains redesigned and get a better application.
