Technology has a never-ending story. It speaks about change and evolution and not about permanence. From film-making to video game consoles, expect that technology will find a way to change these things into something that will interest the public as well as have it coping up with the drastic change of time and society.

From the traditional method of recording films during the pre-war times, there you have modern film-making equipments to help film-makers and producers make their movies very interesting to the viewing public. Fantasy, scientific fiction (sci-fi), and animated movies are now possible with these modern film-making gadgets and equipments. On the other hand, from the 2-dimesional graphics and monotonous audio outputs of Magnavox and Atari video game systems, there you have the seventh generation of video game consoles, such as the newly-released PlayStation 3 and the Xbox 360, which is now the center of attention of the gaming public.

Technology changed the way the people look and use such stuff.

It is not surprising to see communication tools evolve through the course of history. From the Morse code and telegraph mode of communication during the early times come the modern and sophisticated communication tools, which are produced for a single purpose-to provide individuals an effective, reliable, and convenient communication channel in keeping in touch with their friends and loved ones all over the world.

Regular telephone lines started the saga of modern communication system, which allowed individuals to make voice calls anywhere in the world in exchange for a certain fee charge on a per-minute or per-call basis, depending on the telephone service provider. At the later decades of the 20th century, mobile phones were introduced to the market. Such mobile phones allowed a user to make voice calls even if he or she is in a remote area, provided that the mobile phone service reaches such remote area. Satellite phones are also produced to cater individuals who are living outside the coverage area of a regular mobile phone service provider. These are all products of technology to make existing communication systems convenient and reliable for the public to use.

At the early years of the 21st century, the communication industry introduced another form of modern communication, which is said to be the most reliable and cost-effective communication tool nowadays-the Voice over Internet Protocol, or commonly known as VoIP. This latest communication offering is now wisely used for business application and now getting popular among residential and other applications as well.

VoIP differs from other communication system in one thing-communication medium. Unlike in regular telephone lines that make use of underground telephone cables and mobile phone lines that make use of signal towers, VoIP relies on a high-speed Internet connection to facilitate voice calls. Thus, VoIP routes voice conversations using the Internet or other Internet Protocol (IP)-based networks.

VoIP became popular to business applications because it cuts down telephone bills by as much as 60 percent, both in terms of installation costs and monthly bills. You only need to purchase one VoIP infrastructure and upgrade your existing VoIP system if you will need several lines in the future. In addition, VoIP systems are cheaper by about 22 percent in terms of operation compared to circuit-switched networks. That is why the installation cost and monthly billing in VoIP system is cheaper compared to regular telephone lines.

Such advantages prompt telecommunication giants to switch from their traditional phone system operations to VoIP system. One of which is Cisco, which provides VoIP-based structures to help business organizations integrate their communication system closely with their business processes as well as to ensure that information and other data reaches the intended recipients by using the most appropriate medium.

Cisco's primary VoIP offering, which is the Cisco Unified Communication, is now a recognized product in voice as well as in data communication. It combined the advantageous features of networking security and open application programming interface to facilitate an effective business communication channel within the walls of your business organization, which can lead to simplified network management and lower total cost of business operation.

Soon, Cisco will introduce the VoIP system extensively to residential and other essential applications. They are committed to provide an effective and unified communication not just for businesses but for the world as a whole.
