Telephone systems (PBXs) are business telephone systems, the provision of telephone services to the telephone network in the company. All calls are made within the company used by these systems that use shared lines for external calls to traditional PSTN (Public Switched Telephone Network) providers managed. The advent of VoIP, the Internet Protocol for voice communication and use of a standard packet switched data network, led to a full convergence of voice and data management in general. The current IP-based system, such as IP-PBX called use the Internet in order to transfer calls using VoIP, while able to use the PSTN to connect to your traditional phone company in any way. An IP-PBX server, for example, works much like other proxy servers on the Internet (in this case, the exchange of voice data).
L ‘(Session Initiation Protocol) SIP standard, used to control multimedia communication sessions over the Internet all other SIP-enabled phone hardware in your network and free enterprise to use in order for a particular provider and its standard be blocked phone. Most VoIP phone systems have a variety of functions, the auto attendant, voice mail, ring groups include, advanced reporting and even video conferencing. An IP PBX can allow, for example, a company that has offices simply connect their network was much cheaper to intra-office calls.
Today there is an increasing trend towards outsourcing of data operations and IP-PBX systems can be hosted by an external provider in the same manner as all other data processing needs.
Modern telecommunications systems, which together with the help of the IP family of standards, significant cost savings in the management, maintenance and total costs associated with the telephone company infrastructure

Server virtualization technology can run multiple servers on the same hardware, even if they have different server-based applications on different operating systems. Virtualization allows companies to share resources easier and more efficient use of available equipment for processing. Virtualization technology allows companies to purchase the required number of servers and maintain a substantial savings over the life of the offers should be reduced.
But apart from the benefits of server virtualization in the simple cost reduction. The Internet is also smaller companies to be beautiful, and server virtualization technology is a way for small businesses to compete.
Server Consolidation
One of the main benefits of server virtualization is the ability to consolidate servers, reduce hardware costs. the reduction of server virtualization and management of multiple servers into a single device, the company’s resources and costs.
Remember that five servers in each server device can from 50 to 10 minutes. Each server must be updated by internal staff or external providers. Reduce the number of servers can reduce costs and cost savings multiply each installation of the new virtual server.
Less space
Fewer servers, less space and less costly server storage space and a dedicated server.
A small server footprint means lower energy consumption and lower cost of cooling systems. The air conditioning is a particular need for a server room, but reducing the size of the area and the number of servers, so that an air conditioning means smaller and less expensive. Once the basic infrastructure of the virtual server is present, adding a new server is easier than creating a new partition.

Before you begin looking for a new team, decisions that will help you make the right equipment for your needs.
1. Specify whether you have a laptop or desktop.

2.office laptop before, see below for more information.
3. Enter the minimum hardware specifications for new facilities, see hardware specifications for more information.
4. Describe how you plan to buy a new computer.
5. Buy your new computer. Keep an eye on you to my driver, “Configuring a PC, which will cover the basics of the computer configuration and maintenance at regular intervals to keep your computer quickly and safely.

Laptop or desktop
A laptop is a major asset in a desktop, laptop – you can take your laptop anywhere, meaning you instant access to information stored on your laptop, but that makes it easier for someone to escape with your laptop and your data. examine key elements of matter, the CPU (processor), memory, memory (RAM) and HDD (hard disk).
Editor – Controls the speed of your computer can process information.
RAM – This is the temporary memory on your computer when you use the programs and data stored on your computer to access.
HDD – Determines how much information you can store on your computer.
For basic tasks like surfing the Internet, sending / receiving e-mail, word processing and storing photos, videos and music, a computer would be at least a dual core processor, 2 GB RAM and 80 GB hard disk properly the number of photos, videos and music files you have – the hard drive capacity by an increase.
* Buying a computer as an electronics store or department store (like Dick Smith and Big W in Australia).
* Buying a brand computer from a manufacturer through the internet (like Dell and HP).
