摘要
研究目的:随着各种信息技术和计算机网络的发展,Internet在企业中的建设越来越广泛。而基于Internet建立的IP电话系统,每年可为企业节省一笔可观的电讯网络使用费用。故本文在简述IP电话的基本原理、结构及关键技术的基础上,对企业集团基于已建的企业办公网络,配置VOIP网关或IP PBX交换机等有关设备就如何构建适合企业集团的IP电话系统方案进行研究,通过研究提出可构建的IP电话系统方案,并以实例验证该系统方案的可行性。研究结论:通过本文研究,提出企业集团基于已建的企业办公网络和配置有关网关设备,构建企业IP电话系统方案是可行的。实例验证,采用IP电话系统方案比采用PSTN方案经济、合算,每年可为企业节省一笔可观的电讯网络使用费用,减少了企业的运作成本。故IP电话系统是发展的方向。
Research purposes： Along with the development of a variety of Information Technology and computer networks, the Internet is used in enterprise more and more widely. The Internet - based IP telephony system can save a substantial amount of telecommunications network usage costs for enterprises every year. Therefore, based on brief of the basic principles, structure and key technologies of IP Phone system, this article discussed a suitable IP Phone system solution for an enterprise group via configuring the VoIP Gateway or the IP PBX and others related equipment over the corporation internal network. This paper proposes an IP phone system solution which can be constructed, and an example is given to verify the feasibility of the system. Research conclusions：Through this research, the enterprise groups IP Phone system solution, which is based on a built corporate office network extra IP Phone gateway devices, is feasible. The example shows that the IP Phone system solution is more economic than the PSTN phone system. It can save a substantial amount of telecommunications network usage costs for enterprises every year, and reduce the operating costs of enterprises. Therefore, the IP Phone system is direction for the further development.
