摘要
SIP协议具有简单、灵活的技术特点,成为下一代网络中语音信息传输的主要形式。研究基于SIP协议的VoIP体系结构,描述SIP消息结构、呼叫流程,针对基于SIP的VOIP与PSTN网之间协议转换作了深度分析。
SIP protocol is very simple and easy to realize, these advantages show that SIP is more fit for the future development of networks. Provides an in-depth analysis of SIP by describing the SIP protocol stack, illustrating its architecture, message and operation, explains the architecture and the two key aspects of signaling intercommunication when SIP is interconnected with the PSTN.
