Multimedia Networking - VoIP (Communications and Networks) Essay

Multimedia Networking - VoIP (Communications and Networks) - Essay Example Moreover, it enables the companies to perform complimentary telephone calls that make IP-PBX extremely well-known these days. Thus, distant or international phone-calls are becoming a great deal less expensive at this time thus companies are saving a large fraction of expenditures that they had to spend on worldwide and long distance phone calls. Furthermore, IP-PBX presents less costly telecommunication facility that enable businesses to stay in touch with the people in the different areas on the earth. In this scenario, with the adoption of IP-PBX hundreds of businesses have controlled to reduce their operating cost as well as become more beneficial. However, the main need of IP PBX is the accessibility of broadband internet link. In addition, IP-PBX is extremely proficient with respect to its cost and technology. Furthermore, at present Telecom corporations present many IP-PBX technological facilities so that clients could be able to regulate IP-PBX according to their requirements (CallingTools., 2011; TechTarget, 2005). This paper presents a detailed analysis of the IP-PBX technology. This paper also outlines the facts due to which the use of this technology is growing rapidly. This paper will assess main advantages and architectural confines of IP-PBX technology and present its main SIP (Session Initiation Protocol) technology that is a significant promise to provide tighter incorporation between business processes, desktop applications, plus collaboration tools. IP-PBX and Its Principal Characteristics A Private Branch Exchange (PBE) is a user’s site telephone framework that has the capability to handle telephone calls coming to the corporation as well as works as a door for the outside voice communication networks. In this scenario, a network router or switch transmits coming data packets to the suitable data communication network. Conventionally, two different communication networks are required in order to perform this procedure: one network is required for voice and other network is required for data transmission. Moreover, in place of 2 different networks, simply one communication network is preferred when voice data is divided into packets (VoIP) and transmitted on communication network. Furthermore, an IP-PBX is a merger of a router/ switch and a PBX that manages Voice over IP (Silicon Press, 2010). As shown in below given image: Figure 1IP-PBX Working, Source: http://www.silicon-press.com/briefs/brief.ippbx/brief.pdf In an IP-PBX, systems could be connected in a shared LAN (local area network) that is usually connected to the IP-PBX. In this scenario, telephones have to be straightly linked to the IP-PBX. So this configuration eludes QoS (Quality of Service) concerns that could take place if both telephones and computers are configured on a joint LAN. In the same way, communication voice packets will need to struggle with data packets intended for the network based joint LAN. Thus, less effective telephone voice featu re will take place if network voice packets are not broadcasted in a suitable way (Silicon Press, 2010). An IP-PBX works like a gateway that offers voice links (for example voice lines, T1s) to a LEC, a large scope business, etc. as well as data links (DSL, cable, E1, ISDN) to a LEC, a cable operator, an Internet Service Provider, etc. In addition, IP-PBXs
