摘　　要：本文介绍了IP电话的基本功能、特点,并给出了一个基于宽带接入Phone to Phone技术基础而开发的IP电话语音终端系统的硬软件设计。该设计方案改善了传统IP电话语音滞后严重的问题,同时利用已有的硬件建设实现,从而费用低廉,具有良好的应用前景。This article introduces the IP phone basic function and characteristic. At the same time one IP phone terminal implementation including hardware and software design based on broadband access with “phone to phone” technology is given mainly. Because the implementation improve the signal problem of traditional IP phone, and can be carried out by existed equipment, it can be used widely in the future.
