In this paper , investigation of the ip telephony technology transporting real time audio data over the internet which is non - real time network is made first . this paper illustrates the history , advantages , problems and the corresponding solving of the ip telephony technology 本文首先研究了通过非实时的internet数据网络传输实时语音信息的ip电话技术，阐述了ip电话技术产生的市场背景、当前优势、面临的问题以及目前的解决办法。
Compared with traditional telephone , ip telephone is getting more attention for its effective use of network bandwidth , low - cost and provision of diverse add - in services easily . recently , ip telephone tech ( voip - voice over ip ) has made further progresses and improvement , now there are two major protocol stacks , h . 323 protocol stacks put forward by itu - t and sip - based telephone tech by ietf 与传统电话相比， ip电话以其网络带宽利用率高、通话成本低、灵活地提供丰富的增值功能而备受市场的青睐，当前， ip电话技术（ voip ）取得了长足的完善和发展， ip网络电话协议主要有两个，第一个是itu - t提出的h . 323协议栈。
In order to obtain precise information beneficial to company very quickly and improve the employee ' s efficiency , company needs lots of communication and has to spend much money on it , so many companies need ip telephone system that is low - cost and can provide colorful servives . this article try to study and design ip telephone system suitable to these companies 另一个是ietf提出的基于sip的ip电话技术。为了最快获取准确的有利于公司的信息，提高公司的工作效率，企业需要大量的通信，通信费用也十分可观，因此许多企业十分需要成本低、服务多的ip电话系统，本文针对企业的应用研究和设计适用于企业的ip电话系统。
Although the quality of ip telephony is not satisfactory at present , the orientations of its development have been highly valued by the telecommunication industry . many international standardization organizations have been engaging in stipulating system standards and protocols that focus not merely on the ip telephony self but more on the ip multimedia multicast communication and the application of various enhanced services by ip telephony 虽然ip电话的语音质量还不是很完善，但是ip电话技术的发展方向却受到了通信业界的高度重视，许多国际标准化组织正积极制订各种相关的标准，其着眼点不仅在于ip电话本身，更重要的是在于未来ip多媒体多点通信和ip电话的各种增值业务的应用。
After that , i put forward the scm platform based develop solution of the single channel ip phone gateway and discribe the develop hardware platform , software platform and compile tools . i also design the applications software and divide it into several different modules . then i particularly introduce the design and realization of the mainly control module , interrupt dispose module , sdram driver module , nework task dispose module , address transfer module , phone task dispose module and other peripheral equipment driver module 本文首先介绍了ip电话技术及其相关协议；然后分析了ip电话网关在voip网络中的工作原理，比较了其几种可行的实现方案，提出了在单片机平台下开发单线ip电话网关的具体方法，介绍了系统的总体方案，完成了硬件设计选型和软件总体设计和模块划分；接着，介绍了软件开发工具和现有的底层库函数，并对主控程序、中断处理程序、 sdram驱动、网络任务处理、地址映射、电话任务处理、其他外围设备驱动等各个应用软件模块的设计与实现进行了详细的介绍；最后，说明了实验软件的测试结果及今后改进的构想。
Although currently the quality of the voice of voip telephone is not good , it is paid high attention by the communication practitioner . many international standard organization are proposing new related standards , focusing no only on the voip telephone itself , but also on future ip multimedia multi - point communication and various kind of voip ancillary services 虽然voip电话的语音质量还不是很完善,但voip电话技术的发展方向却受到通信业界的高度重视,许多国际标准化组织正积极制订各种相关的标准,其着眼点不仅在于voip电话本身,更重要的是在于未来ip多媒体多点通信和voip电话的各种增值业务的应用。
