摘要
提出了不同于传统H.323协议,基于SIP协议的IP-PBX的研究方案,分析了SIP协议的网络逻辑组成,并依此提出一套解决中小企业、集团企业通信的全业务的IP-PBX系统整体结构,阐述了系统语音、传真、多媒体相关业务流程,总结了实现SIP协议栈的关键组件技术,建立了一个可扩展IP网络增值的基础平台。
Different from traditional H, 323 of IP protocol, this paper gives an architecture of IP- PBX system based on SIP protocol. According to the network element structure of SIP protocol analyzed first, this paper constructs a set of whole-service IP - PBX system which consist of VolP , FolP and MolP services, then induces the key component techniques of SIP protocol stack, provides an extendable platform for IP Network value - added service（VAS）.
