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 technology has swept the world. The biggest advantage of VoIP is that it can widely use the environment of Internet and global IP interconnection to cheaply transmit voice, fax, video, and data on the IP network. The core of IPPBX is PBX voice service and data communication function based on the principle, structure, protocol and signaling of open softswitch technology system. Based on the resources of Blackfin Asterisk IPPBX open source project in the open source community of uclinux, some module systems and design principles of the hardware design of IPPBX are given, and a discussion is also made about the transplantation of software modules. After testing shows that you can achieve the 30-way concurrent use.
