Openh323是为开发使用 H．323协议在 IP网上进行多媒体通信的应用程序 而专门设计 的全功能协议栈 。

该协议栈封装 了大量 H．323实体，功能完善 ，是 v0IP领域一个相 当重要的基础项 目。首先介绍 Openh323项 目计

划．然后描述 了协议栈类库结构，着重说明类的划分和协议过程实现机制 ，并且结合 网守技 术实现的基本思路从进

程模式 、类的继承等方面对如何将 Openbh323协议栈运用到商用 VoIP软件的设计开发中进行探讨。 -Openh323 is for the development of the use of H. 323 IP Internet protocol for multimedia communications applications specially designed full-featured protocol stack. The protocol stack Packaging a lot H. 323 entities, the functional improvement of the area v0IP a very important infrastructure projects. First introduced Openh323 project. Then describe the protocol stack library structure, focusing on such an agreement and the demarcation process Implementation Mechanism, Gatekeeper and integration technology to achieve the basic ideas from the process model, Class of areas, including inheritance to how to Openbh323 protocol stack used in commercial VoIP software design development explored.
