...customers, we have to think about our operational cost and the ways of reducing it. One such way is the implementation of Voice over Internet Protocol ( VOIP ), also known as the internet telephony. VOIP has become more popular in recent years as companies need to cut costs and improve communication between increasingly mobile employees and increasingly global customers. The first Voice over Internet Protocol (VoIP) call was made back in 1995 between two PCs. Initially, this was just a technological novelty. However, by 1998, VoIP had already begun establishing itself as a low cost means of providing calls over long distances. It was estimated to carry about one percent of the US phone traffic. Thirteen years later, VoIP has managed to revolutionize the manner in which business and residential communications take place. Infonetics estimates that about 25 percent of the total international phone traffic is handled as VoIP. So what exactly is VoIP and how does it work? Let me give a few basics about VoIP. Many people have used a computer and a microphone to record a human voice or other sounds. The process involves sampling the sound that is heard by the computer at a very high rate (at least 8,000 times per second or more) and storing those "samples" in memory or in a file on the computer. Each sample of sound is just a very tiny bit of the person's voice or other sound recorded by the computer. The computer has the means to take all of those samples and play them, so that the...

...September 17, 2015 Voice vs. Data Cell phones- wireless phones served by a cellular telephone system broken into small geographical areas. It’s a two-way that carries full duplex conversations. Cell phones have evolve from 1G, which carries information similar to the way fixed line phones transmit voice from subscriber to central office to 4G network for fast access of the internet. It uses both voice and data networks. (woodward, 2012) Landline phones – Initially landline phones started as a device to transmit voice. While it didn’t seem like a good choice to transmit data, however, for many years it was subscribers’ only choice for transmitting data. SMS/Text messaging –The short messaging services (SMS) still works on voice networks. It is the mechanism of sending short messages over mobile networks. The message from the sending mobile is stored in a central SMS center which then forwards it to the destination. SMS can be no longer than 160 characters. (http://www.wirelessdevnet.com) Fax Machine – short for facsimile machine is a device that can send or receive pictures or text over a telephone line. It works by digitizing the image into grids of dots. The dot is either black or white representing on or off. (http://www.webopedia/TERM/fax-machine.html) VOIP (voice over IP) uses VOIP technologies for placing and transmitting calls over an IP network such as the internet, instead of the traditional public switch telephone network (PSTN).

... But the older systems are still around because they need them as a backup in case the VoIP goes down. Ultimately the best solution would be that the VoIP never goes down. There are something in the work that will hopefully provide that avenue for the National Guard and the military as a whole. VoIP and the Military VoIP was is it? It is voice over IP and it refers to the way that phone calls are transmitted through an IP data network, whether that is on the internet or on an internal network. The reason people and especially the military are interested in VoIP is because it has the ability to help reduce expenses because the phone call travels over the network instead of a phone company’s network. Wikipedia’s definition of VoIP is “Voice over Internet Protocol (Voice over IP, VoIP) is a family of technologies, methodologies, communication protocols, and transmission techniques for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.

...Introduction: Voice over IP or VoIP is a relatively new modern way of digital voice communication that relies on many communication protocols, technologies, methodologies, and transmission techniques. The distinctive feature of VoIP is that communication happens over the internet. VoIP is a revolutionary technology that has the potential to compete with the world’s telephone systems. Some engineers have indicated that the creation of VoIP is basically a clever “reinvention of the wheel” that relates to telephone communication. Contrary to the misconception that VoIP induces, it does not deal only with voice transmission. VoIP technology can be considered a medium of transmission also for fax, SMS, voice messaging applications that are transmitted via the Internet rather than the PSTN or public switched telephone network. Some may refer to VoIP as IP telephone but these two terms are actually different since IP telephone has to do with digital telephony systems that use IP protocols for voice communication, while VoIP is actually a subset of IP telephone that transports phone calls and other type of digital information. VoIP has a relatively short history since it began spreading in 1994 as a way of communication developed by some Israeli people. Later in 1995, the first VoIP company launched on the market, "Vocaltec". By releasing an internet phone software that could be added to a computer and its peripherals while using the internet, Vocaltec's software made it possible...

...analysis will explore the current state of the telecommunications industry with the rapid emergence of the Voice-over Internet Protocol (VoIP) technology, wireless communications and the effects on traditional landline or what is known as Publicly Switched Telephone Network (PSTN). This effort will look into current problems and successes with increased focus on AT&T and Skype. Additionally, this paper will attempt to provide a perspective on the key issues with assumptions of what some of the causal factors may have been. Finally, what the companies’ leadership may consider for the future. Prior to examining the key issues of Skype and AT&T, what is Skype vs. AT&T? Skype was currently one of the industry leaders in VoIP and desired to challenge AT&T and other large phone companies. The telecommunication business is certainly going through a technological revolution with increased demands for faster speeds and services. Additionally the infrastructure is in demand to grow with the customer needs. AT&T along with several other landline based companies owned a major portion of the Internet infrastructure. Skype requires access to the Internet by way of Internet Service Providers (ISPs) in order for Skype to provide their VoIP service. AT&T with the other companies currently could not charge Skype beyond the normal rates for access to the Internet. With a looming battle with the large phone companies this presented some key issues with Skype. Skype...

...Major Player’s in the U.S Voice-over Internet Protocol market namely Comcast Corporation, Time Warner Cable, Cox Enterprises and Vonage have embraced internet technology and wireless broadband making VOIP one of the most sought out service. Skype’s partnership with AT&T only fuels the boost usage of Voice- over Internet Protocol usage over land line usage. In the wake of these technology advancements, it became clear to entrepreneurs that offered voice traffic and internet service would be one of the next major applications to take full advantage of Voice-over Internet Protocol. There are more advances than innovations in the VOIP world. That’s because some of the most important developments had more to do with commercial and political maneuvers than with technical creativity. One of the most prominent developments was net net neutrality which enables user access to participating networks that advocates no restrictions to materials throughout the modes of communication allowed online ("The mobile World," 2011, para. 4). Further, this industry also have to consider pressures influenced by the government ( FCC) that could dismantle net neutrality by limited user access as well as decrease the power of big wireless communication giants like AT&T. Still, such maneuvers often helped spread the benefits of VOIP much more than technical innovation. And collectively, the advances brought some already evident trends in the increasing integration of voice with other applications...

...competition among the Voice-over Internet Protocol (VoIP) industry segment, especially as it relates to the relationship between Skype and AT&T and the competition between the VoIP market and the land line market. In analyzing this segment we found that VoIP is a growing industry in what has historically been predominately a land line telecommunication company such as AT&T. The industry segment is faced with a rivalry type competitive market that is currently being influenced by federal government through the Federal Communications Commission (FCC). This agency is considering a new law (Network Neutrality) on the websites that would decrease the power of big telecommunications companies like AT&T. The segment may feel continued pressure from substitutes in the form of other retail segments, but this should not have a strong effect on the over-all competition within the industry. The biggest difference between the competitors was that AT&T used traditional telephone, is run through a public switched telephone network (PSTN) and was much more expensive. Skype offered its customers VoIP, which, defined simply, was the transmission of voice traffic over IP-based networks. In other words, it was telephone via an Internet connection. VoIP is expected to show constantly increasing growth rates in the near future. According to a report by Infonetics Research, the global VoIP services market had reached $15.8 billion in 2006, an increase of 66 percent over 2005, and was on track...

VoIP is a phone service that uses internet connectivity to dial. VoIP stands for voice over internet protocol. VoIP phone service provider can help a business save a lot of money and the ease of implementation and service makes it an attractive choice for business just like Southwest Airlines Federal Credit Union. Southwest Airlines Federal Credit Union wanted to upgrade its phone system in there call center branches in Dallas, Phoenix, and Huston offices. They wanted a system that would be flexible, cost effective, and a scalable solution that would replace their old PBX system that they were using. Their decision to change over to a VoIP phone system was to save costs and easier administration. Using the old PBX system, Southwest Airlines Federal Credit Union had to have multiple servers which in turn made maintenance and support time costly. The other factor was each time they needed to upgrade to the old PBX system, it required substantial investment. Without the newest software for the PBX system, there was no way for them to take advantage of the new features the software update had to offer. They found a solution by choosing VoIP phone system. Their solution to their problem was to implement VoIP for their four call center branches. VoIP would provide a single phone system to cover all four branches and also have room...

However, our focus is our ongoing security and supporting roles for companies who use voice over internet protocol or VOIP services. A recent article in PC Magazine explains that “issues get worse with VOIP calls, which have all of the security issues of the Internet and personal computing. If the person you're calling has a conventional phone line, you've got both kinds of security threats” (Spector, p. 1). As the technology for VOIP expands more cybercriminals will attempt to steal any bit of information that they feel my be profitable if sold to another firm or used by the criminal enterprise in course of a day. Spector continues from page two stating “the digital data of a VOIP call can be intercepted anywhere along the complicated path from your router through the multiple servers until it goes out to the analog phone network. Assuming your VOIP service doesn't encrypt calls, whoever intercepts it can listen to it… (Spector, p. 2)” Model, Inc. started as a small local network repair company until landing an account with Chase Bank in Arizona 10 years ago that changed everything.

...real-time voice traffic to traverse the same packet-switched network. The data traffic will consist of FTP (file transfer protocol) and email traffic and the voice traffic will be a VoIP (Voice over Internet Protocol) implementation. You will experiment with various router queuing policies to see how routers within a TCP/IP network can be utilized to support QoS (Quality of Service) within a converged network that is based on TCP/IP. Explanation and Background Traditional voice and data applications have been kept on separate networks. The voice traffic is confined to a circuit-switched network while data traffic is on a packet-switched network. Often, businesses keep these networks in separate rooms, or on different floors, within buildings that they own or lease (and many still do). This requires a lot of additional space and technical manpower to maintain these two distinct infrastructures. Today’s networks call for the convergence of these circuit-switching and packet-switching networks, such that voice and data traffic will traverse a common network based on packet switching. A common WAN technology used for this purpose is TCP/IP because it operates at Layer 3. It is capable of delivering voice and data services right to the desktop. However, voice and data traffic require different quality of service guarantees, because voice is interactive and takes place in real time, whereas data traffic is non-real-time and can tolerate delays to a much higher degree than voice traffic...
