...History of VoIP Voice over Internet Protocol (VoIP) enables individuals and companies to communicate the delivery of voice communications and multimedia sessions over the usage of the internet. The VoIP industry success is stimulated by the US Federal Communication Commission decision not to control or limit voice traffic over the Net, and the low price of these services. According to the Pike & Fischer’s research forecasts, “ a 14% growth rate for the VoIP market over the next five years, and predicts that 30 million US households will use some form of VoIP by the end of 2010”. (sipnology.com). It is now the year 2012 and the VoIP technology growth is still rising due to the documented benefits that VoIP has to offer our society. “Specialists consider that 31.4 million USA households will use a VOIP as the main and the only home phone line by 2012”, according to SNL Kagan’s ten-year outlook. (sipnology.com). It is obvious that the VoIP technology concept is making a major impact on our society. Statistics show that VoIP is really going to change the way people communicate in the present and the VoIP revolution may be compared with mobile revolution of last years. VoIP is a new technology that has influenced our lives in these ways: political, social, economical, and through the media. The first telephone system was introduced back in the 1870s by the inventor Alexander Graham Bell. He had designed a device that could transmit speech electrically from one point to another...

...is went over a typical wireless local network. I will also provide information on what the advantages to using a wireless network, the problems associated with using a wireless network and what are the best solutions in overcoming these issues. A Wireless Voice network or VoWLAN (Voice over WLAN) is how we send digital voice traffic over a wireless broadband network. The type of wireless set up is basically VoIP sent over a WiFi Access Point. Within the industry this type of VoIP set up is call VoWLAN or WiFi VoIP because it uses the standards set for transporting data by the IEEE 802.11 for wireless technology. In order to use this technology we have to use a VoWLAN enabled device; the most common device on the main stream market is the PDA. There are other devices available like the WiFi handset which looks like a cell phone, but it allows voice data packets sent over the network rather than the normal analog voice signal. One of the other major enterprise level devices is not a device at all. It is software based and is loaded on to a workstation or laptop. This type of software is call softphone. It is a virtual phone that routes call through the WLAN AP to the VoIP gateway or IP PBX. There are some advantages and disadvantages to using this type of technology. One of the major advantages is cost a majority of user have WiFi hotspot available in order to stay connected. “A big advantage of wireless VoIP is that IP phones that work on Wi-Fi networks can be used in place of...

...network consultant hired by Acme Manufacturing, the company has asked Team A to develop a new networking design for Acme’s expanding business. The description below describes the key steps involved in developing a WAN for Acme Manufacturing. The company has six different buildings in six different locations throughout the world that needs to be networked collectively. All the remote locations need to communicate effectively with the main headquarters that is in Atlanta, Georgia. The two buildings that house the headquarters are located across from each other. One building is used solely for corporate operations whereas the other building is for staffing the sales and engineering department. PBX vs VOIP PBX (Private Branch Exchange) is a system that has been around for a while. This allows users to communicate to other users in an office, even without an outside line connected. In a normal environment, the user would have to dial a specific number (or code) to access an outside line. In this way an end user could dial a number that would stay internally. A PBX also allows the users to share the lines that are accessible to the company. If a customer were to call the company on the main line, the receptionist could transfer that call to the salesperson. PBX systems also allow for many other features such as: Voice mail, Caller ID, Programmable phones, Extensions, Hold Music, and ect. The biggest downside of a PBX system would be the number (or extension) is attached to the...

...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...

...VoIP Voice over IP Hani Aladmaai Prof. Ali Bicak IT-520: Enterprise Infra and Networks Introduction VoIP or Voice over Internet Protocol is an IP based approach to transmitting voice over a computer network. It allows a person to make voice calls using an Internet connection instead of using a phone line. The user can make phone calls free (in certain circumstances), or they may get a service provider and pay a very low rate. How VoIP works is, it converts your voice into a digital signal that will travel over the Internet. First to send voice over a digital network, it must first be converted to digital and converted back to analog at the receiving end. VoIP may allow you to make a call directly from a computer, via VoIP programs such as Skype, a special VoIP phone, or your traditional phone connected to a special adapter. The research paper will begin with an introduction as to what VoIP is, what it accomplishes, what purpose it serves and how it works; also how it is configured. Next it will discuss some of advantages and disadvantages. Legal issues will also present on the usage of the VoIP. What is VoIP?

...VoIP as a New Trend Student Name University Name Professor Name 06/20/2010 There is a new trend that has taken the networking technology to the next level. It all started in the 90’s looking for a less expensive way to make phone calls across the world. Both residential and commercial customers have been looking for a cheaper way to make local and international calls. This new revolution is called Voice over Internet Protocol (VoIP). If I had to put this in plain terms, this technology allows voice traffic to be transmitted over the Internet. VoIP is a new application of Internet Protocols (IP) that enables the conversion of voice communications into data packets and then these packets are transmitted via an IP network such as the Internet. “VoIP services convert your voice into a digital signal that travels over the Internet”. (fcc.gov) Similar to using your analog phone system and going through a Public Switched Telephone Network (PSTN), now you will be using a digital phone and going through the Internet. All you need to get the ball rolling and to be part of this new trend is a decent Internet connection at home and you could say goodbye to that plain old analog telephone line forever. Most cable companies are offering service bundles that include cable television, Internet access and telephone services. These companies are transitioning from the telephone analog system to the VoIP systems. A lot of costumers are switching over to VoIP for the simple reason of saving...

...saw in the above list. I think that a cryptanalyst would likely to use the Histogram. I personally think it is easier to read and the information that it gives is very valuable. It gives you the frequency and percent on how many times a certain character was used. Which if I think if I was a cryptanalyst this may help me out in deciphering the encrypted text. Q2. What do you notice about the histogram results when text is encrypted with the Vigenère cipher in comparison to the results of the Caesar cipher? Why is this the case? I really don’t see too much change however, what I have noticed from the first histogram using Caesar cipher vs. using Vigenère I noticed that E is no longer the letter with the most characters used like it was in the Caesar cipher. As a matter of fact it is between L, and K and really doesn’t give a character to use to help decipher it. We know that the letter could be a J but how many words or even phases have a lot of Js in its message? It seems that Vigenere is the better and more difficult cipher to use. Q3. There is an error in the following ciphertext representation of this quote, what is it? What should the correct ciphertext be? (Hint: when using the CrypTool there are several ways to decode one that you can use is “Playfair” encipher option, the plaintext and key provided in the lab information, and DESELECTING the “separate duplicate letters only within pairs” option) SDAHFOWGRABSSRERIVBYBSCIMQTFNIVETGHBSNQCNCSDTDHBSNQCD ECNICIFCTIC ...

...be used in running a business. Consider all types of devices With increase in the technology of smart phones, tablets and other mobile devices, the people are going more mobile. With use of smart phones, everybody is accessing their email accounts and contacts. With the use of some remote access tools, we should be able to access our desktop remotely in our mobile device and access from anywhere. Even for the accounting, the QuickBooks apps generated by intuit would help in maintaining the book. Even the payroll of the company can also be done using mobile devices. The major disadvantage would be the security, because if we lose the mobile devices, there is more chance for somebody to easily hack the information. The term cloud computing stems from the conceptual way the Internet is drawn, specifically as a cloud. Cloud computing is a way of explaining that users are no longer constrained or aware of where the services they are using reside. Both application and databases are moving from being hosted by the particular company to being outsourced to companies that can take entire enterprise applications and make them available to users via a browser.
