Design And Deployment Of VoIP Technology In Enterprise

Softswitch technology is the next generation network (NGN) core technology, and the soft-switch technology is the current hotspot of VoIP technology and applications, the communication based on packet switching technology was widely concerned since it's birth, Particularly as economic development, more and more enterprises set up branches in various places, and set up a dedicated data transmission network. How to make better use of data networks for each enterprise is the focus of attention by the application of IT. IP telephony technology and next generation network NGN given us a better future.Information systems are an engineering company's infrastructure, the company should meet all the demands. Information technology should be used in the works at various stages of the EPC, especially networking, telecommunications, multimedia, database and the other technologies.With China's rapid economic development in recent years in domestic construction of large petrochemical project are many, because the project involves the design, procurement, construction, and other professionals, professional collaboration between the proposed was highly demanded. Computer network and dedicated line system were established to meet the requirement in the temporary offices of construction site, but data transmission was the main purpose for these companies, how to find a better system to ultilized this network for the project is a direction we are exploring, IP telephony (VoIP) technology is a very good choice.This article is based on IP technology division of the telephone system, the view of the current epidemic of IP telephony technology to a certain opinion, covers the principles of the IP telephony, voice coding, VoIP key technologies, to set up IP telephone system.Based on the HQCEC projects phone system, will provide a solution of IP telephone system applied to the construction, chemical engineering companies in areas.At the same time, this system is successful deployed in China Huanqiu Contracting&Engineering Coroperation. Which indicates that the application of this model has a good practical value.
