The modern communications have really evolved. Nowadays, people connect with their peers in other parts of the world through the Internet, which provide for faster and cheaper connection. Yes, because the Internet can facilitate for higher rate of connection, real-time interaction and cheaper costs, it is becoming a more popular venue where people can make calls, just like the way they used to do using land and mobile telephones.

The H.323 is a computer application standard that sets a foundation for data, video and audio communications throughout Internet-protocol based networks. The term is a jargon in modern information technology industry and only a few people have the full extensive and comprehensive knowledge and awareness of it.
The H.323 is defined by online site Webopedia.com as a computer application standard that sets specification for equipment, computers and services for communicating multimedia information and data over networks transmitted across the Internet.

Computer telephony has increased over the years. Technology has allowed the computer and telephone to share data more conveniently and with good quality. Because of the integration of contact channels like email, fax, voice and web service with computer systems, computer telephony has expanded.

With different types of external equipment appearing in the market to accommodate people’s communications needs, VoIP telephony was born. Voice over Internet protocol or VOIP telephony is today’s most popular service that allows users to make and terminate calls over the Internet to landline units. Apart from lower costs, voip telephony offers the same quality service as the traditional landline calls.

The telecommunication network that has helped to overcome the hurdles of distance for communication is the Signaling System No. 7 (SS7). Some of the ways in which SS7 is used in the communication network are the setting up of phone calls, providing cellular roaming and messaging, supplying congregated voice and data services. The evolution of SS7 and its advantages necessitates an in-depth understanding of the Protocol, Architecture and the Services of SS7.

The Voice over Internet protocol or VOIP has really come out and captured the interests and needs of the ever insatiable telecommunications consumers.

Around the world, VOIP systems are being unravelled and launched left and right with the principal purpose of luring more users and eventually generating higher revenues.

Because technology and market demand are changing rapidly nowadays, VOIP systems or IP telephone systems are also evolving at a pace or rate that can be comparable to how data are transferred online.

IP phone systems are the next generation in global communications, what with the continuously growing world market and the need for industry consolidations among companies all over the globe.

Whether you are a small office or a large corporation, VoIP systems are forecast to be a must for every company when the time comes. Not only to IP phone systems help save costs by making phone calls free, they also account for better work efficiencies because all who have access to the single network can enjoy the benefits of standard telephony, while also being able to share huge volumes of information and files.

The boundaries of internet have been spreading far and wide these days. The internet is finding new uses and applications day after day. The most recent inclusion to this field is the concept of VoIP which enables transfer of audio and video data through the internet. Recently, the method of sending fax through VoIP has become popular. Now, the idea of using VoIP for wireless applications is gaining momentum.Wireless VoIP is the combination of VoIP and wireless internet networks. To use wireless VoIP, we need hardware that can support this technology. For example, laptops with wireless VoIP connection and VoIP soft phones have the necessary hardware inside them to support VoIP.

In recent years, the internet technology has grown in leaps and bounds. One major product of this technology is the Voice over Internet protocol (VoIP). VoIP is a technology that enables better audio and visual communication from our home computers. Through this, we can communicate easily from wherever we are and it is cheaper than the conventional telephone services. The upfront investment required for this is also very less. VOIP is still in its early stages and it has to undergo more development before it can substitute the regular telephone.The two types of VOIP protocols used today are:
1. H.323
2. SIP
