基于H.323协议的改进第三方多媒体通信控制协议

A Third-party Calling-control Protocol of Multimedia Communication Based on H.323

改进并建立了一个协议以解决基于H.323网络的第三方通话控制问题。该协议用于H.323的网关守卫连接CTI服务器。通过分析现有的CTI服务，提出了改进的措施。并且简要地介绍了改进的协议的网络环境、组成部分和主要的协议内容。最后给出了一个使用新的改进协议的实例。

This paper develops a new protocol to solve the problem of building a third-party calling control in a network based on H.323. It gives a special protocol with H.323 gatekeepers connected to CTI server and suggests some main features of the new protocol. It suggests some steps to improve the CTI server by analysing the old one. This paper also introduces the network circumstance, constitutes and main contents of the improved protocol. Finally, an example of its using is offered.
