...Introduction Voice over IP (VoIP) is the transmission of voice over packet-switched IP networks, as of right now it is one of the most prominent emerging trends in the revolution of telecommunications (Thermos, 2009). Almost everyone one is driven by technology in one way or the other. With this drastic growth in technology over the pass years and with this rapid growth in advancement it as also presented many ground-breaking improvements; which have contributed significantly to the simplification of day-to-day activities. Nevertheless, this advancement may have a negative effect on the way we communicate using these technology we have come to love. However, with the demand for communication technology on the rise so is the need for additional security. This paper will look at the implementation of VoIP and the necessary security needed in the Enterprise for transmission of safe commination. In addition, this paper will also explain the many advantages and disadvantages (risk) of using a technology such has VoIP in the Enterprise. Implementation Tips VoIP can be very successful in the enterprise if it is done properly using the right techniques and technology that is the right fit for the organization. On the other hand, it can be very unsuccessful and a huge failure. Some companies when considering implementing voice over IP they fail to first make sure that the system is working properly before putting aside their grandfathered system, such as private branch exchange (PBX)...

...Future of VoIP Introduction If we are to considered ourselves as the business aiming at profit increase and progressing growth , thus delivering better quality services to our 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...

...Denetso NTC/362 November 24, 2014 Indp Part 2 Protocols ensure that programs and networks are written in the same format to communicate and work properly. For upgrades to happen, communication must take place for the Patton-Fullers’s network. The Internet has protocols designed for its use and these protocols will integrate into the new system. A small portion of the network architecture is discussed as it fits these new requirements. The increase in network traffic will have an impact and will drive the need for an analysis. Problems and limitations will become clear as long as the analysis concentrates on certain areas. Implementing certain strategies will mitigate the effects the analysis will uncover. Communication Protocols The conceptual framework should already be present with the current Cisco switches and routers already used in the IT data center. The Open Systems Interconnection (OSI) protocol model is a standard seven layer framework utilized by the industry. These protocols are important because they establish the communication rules. Two devices that require each other to communicate on a network must follow a set of rules to ensure they are compatible to each other. The seven layers of the OSI specify the hardware and software component requirements to ensure that the collection of these is adequate enough to exchange information on the network. The inclusion of a WLAN, WAN, and VoIP will require additional protocols that are unique from the OSI. Required Protocols ...

...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 major...

...Fundamentals of Networking Dean McIntyre 2 The Patton-Fuller Community Hospital looks to upgrade their Information Technology (IT) capability beginning with their networks. The characteristics, components, and topology are evaluated to properly identify the needs for the new network design. The plan includes converting to a Wireless Local Area Network otherwise known as (WLAN), installing a Voice over Internet Protocol otherwise known as (VoIP), and design a Wide Area Network (WAN). The plan also includes the hospital maintaining all Macintosh® computers. Administration/Clinical Overview * The administrative departments run off of a 1000 Base-T Ethernet provided by a CAT 6 cable which is also the entire hospital’s network backbone. Clinical department networks however are provided by a 1000 Base-F Ethernet provided by a single mode fiber. The clinics feed into a Cisco Catalyste 3560 Switch as the network bridge that links the two together. All workstations are Apple iMAC or MAC Pros with the executive management, senior managers, and the data center workstations as having a wireless communication card installed. * IT Data Center * The data center is comprised of the hospital HIS system. The mainframe of the HIS is connected by a 4 gigabit fiber link to a 10 terabyte Network Area Storage (NAS) device. The data center’s workstations are all Apple iMACs that run a MAC OS X from a remote desktop. Virtualization allows for operating Windows and...

...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 the...
