嵌入式IPPBX的研究与实现

Study and Implementation of Embedded IPPBX

VOIP技术已经席卷全球,VoIP最大的优势是能广泛地采用Internet和全球IP互连的环境在IP网络上便宜的传送语音、传真、视频、和数据等业务。IPPBX的核心是以开放的软交换技术体系的原理、结构、协议和信令等为基础来实现PBX语音服务和数据通信功能的。基于uclinux开源社区的Blackfin Asterisk IPPBX开源项目资源,给出了IPPBX硬件设计部分各模块系统和设计原理,针对软件模块的移植也做了相关讨论。经过测试表明,可以达到30路的并发使用。

VOIP（Voice over Internet Protocol）Technology is now sweeping across the world, and the biggest superiority of VOIP is the extensive use of Internet and the global IP interconnection for transfer of voice, fax, video, and data services .IPPBX （Private Branch Exchange Over IP）, based on open system theory, architecture, protocol and signaling of the softswitch technology, could achieve PBX-based voice services and data communication. This article describes principles and structures of IPPBX hardware design based on Blackfin Asterisk IP-PBX open-source project resources of uclinux open source community, discusses the transplant of software modules. Test shows that the processing of 30 calls could be achieved simulataneously.
