VOIP:
Voice over Internet Protocol (VoIP) can be defined as a series of technologies and technique that is used for release of voice communications and multimedia through Internet Protocol networks. In some cases, this technique is referred to as a means of converting analog audio signals into digital data that can be delivered through an Internet Protocol. The use of the technique is attributed to its ability to transform standard Internet connection into a platform for free phone calls. In the past few years, Voice over Internet Protocol has emerged as an innovative technology with the capability of completely transforming phone systems across the globe. As a result, VoIP providers have not only existed for a considerable period of time but are also growing steadily. However, the use of VoIP to rework modern phone systems is characterized by several advantages and disadvantages.
Use of VoIP:
The use of Voice over Internet Protocol is primarily an intelligent re-invention of the wheel in the world's phone systems. Generally, this technique involves transmitting voice information in digital format in distinct packets instead of using the conventional circuit-committed protocols of the public switched telephone network ("VoIP (voice over IP)," n.d.). This technique was developed following initiatives by major equipment providers to enhance the use of standard measures for transmitting voice and video using Internet Protocol within an intranet and across the public Internet. This was achieved through the VoIP Forum, which also supports the use of directory service standards for users to identify other users and the utilization of touch-tone signals for automatic distribution of call and voice mail. The use of this technology involves positioning a device at a gateway, which obtains packetized voice transmissions from users within the organization. The gateway then routes the transmissions to other segments of its intranet or transmits them through the public switched telephone network.
According to Valdes & Roos (n.d.), there are three varying methods of VoIP service...
12). Each would require however separate DHCP servers so that firewall protection could be easily integrated within the system (Kuhn, Walsh & Fries, 2005; Flatland, 2005). H.323 SIP and other VOIP protocols can be disconnected at the voice gateway that interfaces with the PSTN to allow for stronger authentication and access control on the gateway system (Kuhn, Walsh & Fries, 2005). However this can make key management problematic. Other
Security measures are available to minimize this effect, in fact an entire industry has emerged to address these needs, but control will never be the same as when the employees are under one roof and subject to scrutinizing eyes and ears and computers and cell phones are free from potential hackers. To put virtual office security into perspective think about all the security measures that are taken in traditional offices
Telecommunications Trends in Voice over IPs Voice over IP is a term that is often used in what is known as Internet Telephony, where a voice can be used to deliver the IP or the Internet Protocol. When it is used in Internet Telephony, it is generally a set of facilities that aid and control the use of IP with regard to Voice Information. It also means that the voice can
Wireless Broadband Technology Overview of Wireless technology Presently it is quite evident to come across functioning of a sort of wireless technology in the form of mobile phone, a Palm pilot, a smart phone etc. With the inception of fast connectivity in the sphere of commerce it is customary and useful to operate from central locations communicating with the remote branches, conducting conferences in remote places, discussing with every body at every

After eliminating from further analysis those that did not meet the criteria, the remaining products were reviewed from an administrative perspective." (p.1) Stated as being particularly important were "…compatibility with
VOIP With the advent of information technology, the ways different aspects of life work and operate have changed a great deal. The advancement in telecommunication sector have revolutionized and redefined the communication systems at all aspects around the world. The process of bringing the world closer that started with the invention of Morse codes has now entered an era of its own where distances of miles are bridged to a few
