基于G.729A的IP电话系统设计
Design of IP Phone System Based on G.729A
【摘要】 研究并实现了一种基于G.729A语音编码标准的IP电话系统,集成了Windows底层音频接口、线程同步机制和WinSock通信等关键技术,利用普通全双工声卡,较好地实现了PC-to-PC的窄带全双工实时数字语音通信功能。
【Abstract】 This paper gives a introduction of the research of IP phone system based on G.729A codec, which also integrates Windows low-layer audio API, thread syncronise mechanism and WinSock communication technologies.Through full-duplex Audio card,it satisfactorily realizes PC-to-PC’s full-duplex real time voice communication in narrow-band network.
