VOIP SECURITY
Introduction
Voice over Internet Protocol (VOIP) also referred as IP Telephony is a technology that is used as the transmission medium for Voice calls over the computer network.This is evolved from “Digital Signal Processing” which converts the voice signal from your telephone into a digital signal that travels over the internet. VOIP is attracting a lot of attention today. There are many reasons for this like VOIP seeks to deliver many business benefits for example,integrating voice in data communications, and it is much more flexible.
History
Traditional phone lines are slowly being expelled from the communications market with the growing new technologies. The actual transmission was taken place in 1973 as a result of the Protocol invented for the ARPANET, while origin of VOIP is first announced in 1995 by an Israel company called Vocaltech which allows users to call via computers. This product works only when if both sender and receiver had the same software setup.
Present
Over the last 14 years the process of VOIP showed a tremendous increase in the telephony world. Early suppliers of voice over IP administrations offered plans of action and specialized results that reflected the structural planning of the legacy phone system. Second-era suppliers, for example, Skype, have manufactured shut systems for private client bases, offering the profit of free calls and accommodation while possibly charging for access to other correspondence systems, for example, the PSTN. This has constrained the flexibility of clients to blend and-match outsider fittings and programming. Third-era suppliers, for example, Google Talk, have embraced the idea of united VOIP, which is a takeoff from the structural engineering of the le...

It is crucial that individuals take precautions when using technology to have conversations with others. Due to the fact that it can be dangerous, effective telephone communication is very important. Before using technology as communication devices, it is a good idea to know the main issues regarding it. It is also a good idea to know about any recent developments and how it affects its users. By making sure the technology has high ratings and positive feedback, there is a greater chance that you will be happier with the outcome of your purchase.
Using a high-speed Internet connection or ISDN, a video connection is established; a qualified sign language interpreter relays the conversation with the voice telephone party.
Phones have come a long way from their beginnings. When the first phone was developed, a mere phone call took up to ten minutes just to connect. The calls made on this phone would go through a system of connections where the caller would have to state who they were calling and where the person lived. It would be many years later that a telephone would be created that made use of a dial, which made calling easier. In 1963, the first pushbutton telephone was distributed by the company, Bell Telephone. In 1983, the first cellular device, the Motorola DynaTAC 8000X, was created, which took the world by storm. Soon later, miniature computers were being put in these devices, allowing the user to browse parts of the web while on their cellular device. Yet we wouldn’t see a product that allowed us to browse the web, communicate with others, and let us store music and run apps, until 2007. (ht...
Background One. Tel was launched by Jodee Rich and Brad Keeling in 1995 (Cook, 2001).

Filing information and documents (manually and using computerised databases) and being able to find them again when necessary. They must also ensure confidentiality of private and sensitive information.
This will give us the advantage of sending very large pieces of information over the phone line. The only thing that we do know about the telephone, is that it has come a long way since its first discovery by the inventor Alexander Graham Bell. A man who will always be remembered.
Cell phones have become a part of mainstream culture. Recently they have become more affordable and accomplish much more than making and receiving calls. Along with the growing popularity there is also growing concerns about safety and health. In this paper we will address cell phone history and how they have evolved. We will discuss health concerns such as tumors and talking while driving. Finally, we will talk about all of the technology that cell phones can accomplish such as receiving Email and buying stocks.
Modems originated as a way for teletype machines to communicate over ordinary telephone lines. When the US Air Force needed a convenient way of transmitting hundreds of radar images to command centers during the Cold War in the end of 1940s, they turned to the telephone system and modems as a solution (Dalakov 2014). Thus, first digital modem was developed in 1950s. In 1962, the first commercial modem was manufactured – the Bell 103 by AT&T. The Bell 103 was also the first modem with full- duplex transmission, frequency-shift keying, and had a speed of 300 bits per second (Wright 2014). For many years, AT&T hold a monopoly on the phone system in the United States, so only AT&T could provide modems to work on its network (Edwards 2014). Companies got around this restriction by inventing the acoustic coupler, which hooked a radio or modem to the telephone system via a cradle in which the user placed a standard phone handset. This way, the modem c...
On March 10th, 1876, a revolutionary invention was created by Alexander Graham Bell. The telephone was invented to send vibrations from one receiver to another electrically (History.com ‘Speech Transmitted by Telephone’ accessed on March 11, 2014), and due to Alexander Graham Bell accidentally discovering that he could hear the sound of a ‘clock spring twanging’ (Marry Bellis, ‘The History of the Telephone’ accessed on March 11, 2014), that was possible. The invention of the telephone permitted new levels of communication, allowed families connect around the world, and improved military systems, but also served negative consequences, such as breached privacy. If two people wanted to have a conversation, they would have to write letters back and forth, but with the telephone they were able to pick up the receiver, dial the number, and be connected in a matter of minutes. Telephones enabled long-distance communication, which allowed families to converse despite their location. Military officials and soldiers were also able to stay in touch through field telephones as well as keep contact with the president. Although telephones were originally placed in general stores or other major city locations and homes/neighborhoods that were wired (Elon.edu ‘World Changes Due to the Telephone’ accessed on April 2, 2014), telephones became commonly used in homes in the early twentieth century when telephones began to connect internationally.
Despite the short amount of time since the introduction of the smartphone, the rapid development of the software and technology has had a tremendous effect on the everyday life of society today. The concept of communicating through a telephone was developed in the 1870s. Devices to transmit speech electrically were designed by Elisha Gray and Alexander Graham Bell, but Bell's design was patented first. On March 10, 1876, Alexander Graham Bell achieved one of his greatest successes in the making of the telephone. This brought upon a major change in communication and gave leeway to the improvement of the telephone in the days to come (Bellis, 2013b).
