Telephony no longer requires a telephone with voice over IP (VoIP), a means for using the computer to transmit and receive the voice just as a telephone has been doing for a century. Some companies are shifting from PBX systems to VoIP systems, but there are a number of concerns raised by these systems that prevent many companies from making the switch, including cost considerations and issues related to the adoption of standards. VoIP has several advantages. It consolidates the voice/data network infrastructure; allows easier moves, adds, and changes to the system; and can consolidate interoffice voice traffic onto a wide area network, thus replacing off premises lines and tie lines provided by telecommunications companies. VoIP also allows easier integration of voice for call centers and other applications (Mitchell 50). Observers also note that there are a number of problems implementing VoIP, including the fact that installation costs are the same or more than for a PBX while the systems in use still lack many features found in PBXs; analog integration can be problematic; consultants with the required voice and data experience are in short supply; and standards for powering phones over Ethernet, such as call control protocols, are still evolving (Mitchell 50). A recent report on VoIP suggests that businesses might be able to cut their telecoms operating costs by half by switching to a VoIP network. The report was published by Cambridge based Analysys, and it also notes that the cost of setting up a VoIP network is higher than for traditional private branch exchanges (PBXs). This means that those adopting the new system will probably make the switch because of the enhanced features available with VoIP rather than for the savings. The report states that companies can save 49 percent on operating expenses by migrating to VoIP,...

...VoIP and the Military Abstract The Army National Guard responsible for the safety of the State in case of a natural disaster or any sort of force that threatens the population of the State. They are also able to deploy overseas in any conflict that the United States may get involved in. Communications is on something that is very critical to the job they do and they are always looking for the newest and greatest way to accomplish their mission and do so with the best communications platforms available. Currently VoIP has been the newest and greatest thing that the Army National Guard has been able to harness. It is proving to work extremely well throughout the states due to its flexibility and reliability. 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.

...The internet is fast evolving into a universal communication network. Among them, telephony is an application of great importance. Voice over Internet Protocol, commonly known as VoIP, is a technology used for the transmission of voice information using the Internet Protocol (IP). VoIP simply means running a telephone service over broadband connection. VoIP allows the sending of voice information in a digital form using packets over packet-switched networks as opposed to the traditional circuit-committed protocols of the Public Switched Telephone network (PSTN). Traditionally when one wishes to make a phone call, a call is placed using a telephone that is connected to a circuit-switched network. In a circuit switched network, network resources are static; the network resources are allocated from the sender to the receiver before the start of the voice transmission. Two points are connected in both directions thus creating a "circuit". The resources remain dedicated to the circuit during the entire transfer and the entire voice transmission follows the same path, this is the foundation of the PSTN. The basic principle in which the VoIP works is known as ‘packet switching’. Instead of sending a continuous stream of bytes, in VoIP, the bytes are sent only in packets. These bytes are routed through a chaotic network, instead of a dedicated line. The entire process is known as packet switching. In packet switching, the connection is opened for only a brief instant, just......

...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 Joseph H. Murray IT / 245 Intro to WAN October 8th, 2011 LaTrea Shine Due to frequent outages in the digital subscriber line network serving over 50 corporate-owned Gold’s Gyms; a VP Bobby Badugu knew it was about time for a significant upgrade (Desmond, 2006). He looked into a various amount of solutions including satellite, frame relay and even a different DSL provider; after carefully assessing each option he chose to go with a VoIP service. This is where his decision turned out to be a problem rather than a solution to their current issues. In the time following the decision Badugu learned some valuable lessons about not only VoIP, but major network projects that involve upgrades to numerous far-flung sites. He decided to share his insights in a presentation at the Network World IT Roadmap Conference in Dallas. Some of what he said included using a phased implementation process, establishing clear SLAs, including penalties, and conducting a thorough technology assessment to identify potential problems (Desmond, 2006). As the rollout for the change was announced it was scheduled to take only 8 weeks to complete; this was in June. In mid November while the data rollout was complete, only 20% of the voice lines have been ported over to the VoIP network (Desmond, 2006). Badugu remained headstrong to push on through expecting savings in the amount of 35 to 40 percent in voice and data service costs (Desmond, 2006). The......

...vs. at&T Skype vs At&t Case Study 1. What are the dominant economic characteristics of the VoIP Industry? PSTN charges based on minutes or even seconds while VoIP charges based on data usage. VoIP services often charge a flat fee and in Skype’s example, they offer free talk between Skype users. VoIP is also inexpensive to operate as the infrastructure is already there. VoIP is also considered part of the information service industry and not the telecommunication service industry giving it an advantage politically against PTSN (compliance with telecom laws). Against PTSN, VoIP is expected to grow substantially and is eating away at the market share of PTSN. 2. What does the five forces analysis reveal about the chances for profitability in the VoIP industry? (Prepare a five forces analysis) Threat of Substitues: Substitute for VoIP is low – as it is a substitute for PSTN Threat of New Entrants: The threat of new entrants is high in this market. As a rule in economics, companies will enter this market until there is a profit to be earned. Companies like Microsoft, Google, and AOL are just a few that are planning to compete in the VoIP market. Bargaining power of Buyers: The bargaining power is moderate because of the ease of switching to other companies. Customers are “fought for” among competitors.

...topology and data traffic, voice traffic (text format), supporting documentation Your role as design engineer is to analyze current enterprise data network and find out if and how it can be used to support VoIP requirements. Both data and real-time VoIP have to share common IP infrastructure, thus, the traditional TDM-based voice network can be turned down. Part I: In this project you will be required to reengineer current network in the most optimal way considering routing optimization, use of Traffic Engineering, MPLS and QoS, bandwidth upgrades or and topology changes. You also need to consider single points of failure as this may change the baseline condition and degrade VoIP and/or data performance. Your analysis should consider and compare these codecs: PCM G.711, PCM G.711 (with silence suppression), G.729 A, G.729 A (with silence suppression), G.728 16K and G.728 16K (with silence suppression) – final codec selection needs to be optimized including other requirements for the project. Your design solution should satisfy following constraints: - 4.0 or higher MOS for more then 99% of the total voice traffic - Link utilization on any of the interconnecting links should not be above 85% - Grade of Service of 99% should be met - Delay for VoIP e2e bearer...

...Chapter 1 R4. List six access technologies. Classify each one as home access, enterprise access, or wide-area wireless access. * For Home access we can use the following access technologies: 1. Dial-up modem over telephone line 2. DSL over telephone line: residential or small office In locations where DSL, cable, and FTTH are not available (e.g., in some rural settings), a satellite link can be used to connect a residence to the Internet at speeds of more than 1 Mbps; StarBand and HughesNet are two such satellite access providers. Dial-up access over traditional phone lines is based on the same model as DSL—a home modem connects over a phone line to a modem in the ISP. Compared with DSL and other broadband access networks, dial-up access is excruciatingly slow at 56 kbps. 3. Cable to HFC: residential; While DSL makes use of the telco’s existing local telephone infrastructure, cable Internet access makes use of the cable television company’s existing cable television infrastructure. A residence obtains cable Internet access from the same company that provides its cable television. Each neighborhood junction typically supports 500 to 5,000 homes. Because both fiber and coaxial cable are employed in this system, it is often referred to as hybrid fiber coax (HFC). * For use at firms or enterprise access 4. 100 Mbps switched Etherent Ethernet is by far the most prevalent access technology in corporate, university, and home networks.

Voip Introduction

...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......

From what the article states, this company needs to have the best communications system possible. It also states that the company claims to have the same expectations and up time as hospitals do. This case study shows how the VoIP system would benefit the company and how much money they would save by switching over to this new system. The company was working on a low budget and did not have enough money to install the CAT 5E cables that are necessary for this type of phone system or so they thought they were necessary. This company had very old wiring system throughout the buildings and would have to spend a lot of money to update the wiring. They started out using the original Cat 3 cable that was already in the building. After six months of converting over to the new phone system with the old wiring they made a deal with a wiring company to come in and replace all of the old wires with new ones at the end points. Prior to installing this new phone system the company would spend about $50,000 in dial cost over their old phone system. After installing this new......
