摘要
IPPBX(PBXoverIP)是VoIP(VoiceoverIP)领域内的一个研究热点。IPPBX将企业内部现有的数据网与电话网融合,是企业与公共交换电话网PSTN(PublicSwitchedTelephoneNetwork)、IP网等外部网络通信的桥梁。本文基于现有的多个IPPBX系统抽象出两种最常见的模型,并在此基础上改进后,提出了一种适合中小型IPPBX系统的结构模型。
IP PBX (PBX over IP)is a research hotspot in the VoIP domain. It is the key technology to bridge the telephonenetwork and data network inside enterprises. IP PBX device establishes communication between enterprises and outsidenetworks. This paper abstracts IP PBX's two commonly-seen architecture models and brings forward a new architecture model,which suits the medium and small IP PBX system.
