摘要
SIP是NGN(Next Generation Network)呼叫控制中的一个重要协议,其应用研究正方兴未艾。该文基于NGN关键设备——媒体服务器的开发实践,对其中运用SIP控制媒体服务器提供多媒体业务进行了说明和讨论,特别以交互语音应答(Interactive Voice Response,IVR)为例,给出了一种用SIP及其扩展控制多媒体会话的具体实现方案。
SIP is a very important protocol for call-control in next generation network (NGN) and the R&D of it is well going all around the world. The article is based upon the development practice of a key NGN equipment——media server. It describes how to use SIP to control media server to provide media services in NGN. With the example of interactive voice response (IVR), it gives a solution of using SIP and its extensions to control multimedia session and analyzes the merits and demerits.
