Introduction

VoIP Systems are seen as complex communication infrastructures even from a high level perspective, but they’re not. Well, VoIP is in fact complex in its details, but it has been abstracted by various projects in order to make it really straight-forward to use it, so it’s easy to start a compelling voice/video communication system or service (which I’ll name “VoIP system” or “VoIP service” throughout the document) from scratch, but it’s important to learn a few facts about it in order to choose the right base system for successfully running a VoIP service.

The Basics

VoIP just means “Voice over IP”, which is a generic term for transporting real-time voice sessions over the Internet. However, it doesn’t define HOW this is done, and even the term “Voice” is a bit misleading, because with the very same concept, you can transport also Video and Fax over an IP…...

...MIS535 – Managerial Applications of Information Technology Course Project: Installing an IP Phone System Company Information and Abstract: Holt’s Cigar Company has been in business for over 100 years. The first store opened in 1898. There are now two retail locations in the Philadelphia area. Holt’s also provides a mail order service where cigars can be purchased online or by phone in most states. Holt’s Cigar Company is also part of Ashton Distributors. The same person owns them. Holt’s is the retail store and Ashton is a wholesale company. The total amount of employees for both companies is around 100 people. I work in the IT Department. We are in charge of maintaining the network, helping users, and maintaining the phone system. The phone system is over 10 years old and is an analog system. This system runs off of Windows Server 2000. Windows Server 2000 is very old software and Microsoft does not support it anymore. So this means there are no new updates or patches to software. This can leave our phone system open to outside attacks from hackers. Our biggest problems with the current system are functionality and features. The system randomly stops working about once a week and this usually occurs during business hours. The server needs to be re-booted when this happens. The IT Department cannot re-boot this system remotely. It must be manually re-booted at our Northeast Philadelphia location where it is housed. The phones will not work at......

System Building

...System Building April Willochell Digital Firm There are a number of alternative methods for building information systems, each suited to different types of problems. The oldest method for building systems is the systems life cycle, which requires that information systems be developed in formal stages. The stages must proceed sequentially and have defined outputs; each requires formal approval before the next stage can commence.” The system life cycle is useful for large projects that need formal specifications and tight management control over each stage of systems building.” ( Building Systems History, 2012) However, this approach is very rigid and costly and is not well suited for unstructured, decision-oriented applications for which requirements cannot be immediately visualized. Prototyping consists of building an experimental system rapidly and inexpensively for end users to interact with and evaluate. The prototype is refined and enhanced until users are satisfied that it includes all of their requirements and can be used as a template to create the final system. Prototyping encourages end-user involvement in systems development and iteration of design until specifications are captured accurately. The rapid creation of prototypes can result in systems that have not been completely tested or documented or that are technically inadequate for a production environment. Developing an information system using an application software package eliminates the need for...

Industrialised Building System

...1.1 Introduction Industrialized Building System (IBS) is the phrase used by the industry and government in Malaysia which stand for the adoption of construction industry and the use of prefabrication of components in building construction. IBS is defined as a construction technique in which components are manufactured in a controlled environment (on or off site), transported, positioned and assembled into a structure with minimal additional site work [1-4]. It consists of precast component systems, fabricated steel structures, innovative mould systems, modular block systems and prefabricated timber structures as construction components [3]. Parts of the building that are repetitive but difficult and too time consuming and labor intensive to be casted onsite – are designed and detailed as standardized components at the factory and are then brought to the site to be assembled [3]. The onsite casting activities in IBS utilize innovative and clean mould technologies [1-3]. The construction industry has started to embrace IBS as a method of attaining better construction quality and productivity, reducing risks related to occupational safety and health, alleviating issues for skilled workers and dependency on manual foreign labor, and achieving the ultimate goal of reducing the overall cost of construction. Apart from this, it offers ......

By understanding the basic approach used by hackers to target organizations, you will be better equipped to take defensive measures you will be better equipped and know what you are up against. There are steps involved in scanning a network, the following points will highlight them. 1) Check for live systems, 2) Check for open ports, 3) Fingerprint the operating system, 4) Scan for vulnerabilities, 5) Probe the network. Tools that can be used to detect scanning threats and countermeasures that a company can use to deter and avoid vulnerabilities are as follows. “Spoofing user identity -use strong authentication for passwords, do not store secrets (for example, passwords) in plaintext. Do not pass credentials in plaintext over the Internet. Tampering with data –use data hashing and signing, use digital signatures, use strong authorization, use tamper-resistant protocols across communication links, secure communication links with protocols that provide message integrity”.

A Systems Approach to Building Science

...Building Science - GEORGIA - Too Much Government or Not Enough? I believe in limited Government intervention into the lives of its citizenry. Government neither can nor should try to solve all of our problems; but there are times when it can “stimulate-by-mandate”, rational focus. For example: Residential Building Science has changed little in the past 50 years; Rip Van Winkle Builders could emerge from a 50 year nap, build a home today, and it would pretty much fit in with the neighborhood. However occupant’ lifestyles have changed dramatically. We have added moisture sources with multiple indoor bathrooms, showers, tubs, Jacuzzis and clothes washers; we have added exhaust appliances like bath & range vents, clothes dryers and fireplaces; we’ve added more doors & windows plus huge HVAC systems with leaky ductwork & connected garages. We spend more time in our homes with home offices, computers, video games, televisions (did you know that one person, breathing for 24 hours yields one gallon of water?). Our manufacturers have become more “technologically advanced” and are using tremendously toxic stuff in those things with which we adorn our home - from paint to carpet to furniture to cabinetry … into perpetuity. Air infiltration/exfiltration, and the moisture, mold and mildew that accompany it, is the single largest threat to a safe, healthy, comfortable, durable and energy-efficient home. All air flow needs is a pressure differential and a pathway to exchange......

Voip Advantages and Disadvantages

...VoIP Advantages and Disadvantages The pros and cons of IP technology by Daniel Kochmanski DDK Telecommunications Buffalo, New York VoIP (Voice over Internet Protocol) is the ability to transmit and receive voice telephone calls over an Ethernet data connection. Ethernet data connections are used to connect computers inside an office building across a LAN (local Area Network) also known as intranet as well as connect computers to the world wide web (www) also known as a WAN (Wide Area Network) or internet. I must explain that VoIP (Voice over Internet Protocol) is utilized in two different ways. The first method, and the first one created, is for inbound and outbound phone service via VoIP service providers. The service can be via SIP (Session Initiation Protocol) trunking or a VoIP adapter. The second method is utilizing VoIP signaling directly to a business multi-line telephone is known as an IP (Internet Protocol) based phone or IP phone for short. I shall explain the advantages and disadvantages of IP business phones later in this article. I’ll also explain why a Hybrid system may be your best solution in the final paragraph. VoIP service provider companies, such as net2phone (IDT Corp) and iConnectHere (DeltaThree Corp.), started selling VoIP phone service back in the 1990’s. My personal experience back then was that the quality was very poor mostly due to lack of sufficient bandwidth, internet speed and compression techniques. Today there are......

When You’re Big, You Can Be Your Own B2B E-Marketplace

...MARMONEJO, Irene Kristelle A. BUS. IT 3 1/19/2015 VASQUEZ, Rachelle Joy G. WHEN YOU’RE BIG, YOU CAN BE YOUR OWN B2B E-MARKETPLACE Questions: 1. Volkswagen operates its own proprietary B2B e-marketplace in which its suppliers participate. What are the disadvantages to Volkswagen of not using a generic B2B e-market place with even more suppliers? What are the advantages to Volkswagen of developing and using its own proprietary B2B e-marketplace? Not operating a generic B2B e-marketplace brought disadvantages to Volkswagen at some point. Not using a generic B2B will result to no new trading partners, difficulty in finding suitable partners, no open infrastructure standards, making it more difficult to plug into other than proprietary technology and significant technology costs. A lot of time will be wasted searching for good deal to purchase large quantity from over thousands of suppliers. The company will also have to go through many steps just to complete hundreds of transactions which mean loss of opportunity cost of negotiating for better prices with the suppliers. On the other hand, developing and using its own proprietary B2B e-marketplace brought advantages to the company. It reduced administrative tasks, accelerated processes, improved planning accuracy and improved transparency in collaboration with suppliers. There will be an ease in ordering of parts since there are 5,500 suppliers to interact with, both local and......

...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. Wikipedia’s definition of VoIP is “Voice over Internet......

Building Your Own Computer

...Building your Own Computer It is increasingly popular to build your own computer. In most cases, it saves money, and it guarantees you get what you want. It also assures you avoid proprietary designs many companies use to keep you coming to them for new parts. Best of all, having built the system yourself, you become very familiar with that system and with computers in general. People from all walks of life today build their own PCs. Executives, engineers, students, housewives, they all do it today. But, at the same time, pre-built PCs have come down in price quite a bit. Today, one is left to wonder whether it is best to build a PC yourself or to simply buy one off the shelf. I’ll address that here. If you are a real PC enthusiast, this question may be a non-issue. The answer may be as obvious as the color of the sky. This is predictable, of course. When one builds their own PC, they are able to not only understand their PC better because they built it, but they are able to choose each component that goes into their PC. There is really something to be said for choosing your own components, and I’ll go into that further below. There is also a certain sense of satisfaction with having built a PC. One spends a few hours (or less for those more familiar with the process) to put the thing together. Then comes the moment of truth when one hits the power switch for the first time. If it works on the first try, its beer time! But, besides the joy of it, is it worth it? Is......
