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

with the computer as a global communication tool of export and import of industrial products between the countries, such as commercial communications by e-mail or check e-mail faster than the speed of light.
Trade between the countries importing the progressive elimination of barriers to imported products on the market in the country with a significantly reduced price for these products through price cuts for production functions performed.
Because the team, business process outsourcing, BPO countries football, like India, Philippines and South Africa’s economy and provides thousands of jobs in the world of work. The countries are in the process of “outsourcing” the other side, more support for their economies if they are exempted from payment of fees in their countries that the cost of cheap labor in other countries, which reduce. The data show that sales in India totaled $ 30000000000 $ 10900000000 safety BPO offshore IT and BPO total in 2008, representing 5.6% of the BPO sector as a whole.
The computer and the Internet in a shopping center, where scientists and researchers, pharmaceutical companies, including alterations to some drugs, the development of new drugs are better than existing drugs and discovery of new and promising huge profits and production exclusive distribution transferred in a while. As the competition gets stronger, companies, different marketing strategies for the sale, the consumer ultimately increases the benefit of all products.

Regardless of the size of the country and its people is the telecommunications industry also crucial to the country’s financial system and the interests of citizens living there. Earlier in the telecommunications sector in the traditional fixed telephony and cable networks. Currently, mobile telephony, broadband Internet service, packet radio and satellite television systems, additional services that fall under the category of telecommunications.
Technological advances in communications technology, the world is completely connected. People from different regions of the world that does not meet only very slightly, but will also provide information to the other end without the use of cell phones, Internet and GPRS.
The telecommunications sector is divided into two zones. The first use of cable and the other is wireless. with wireless telecommunications technology that is preferred by most people these days due to the simplicity and mobility.
The standard cable and fixed telephony, the cable TV networks, cable and wireless connections for popular models of telecom products. On the other hand, mobile phones, Internet access, including Wi-Fi, General Packet Radio Service the largest case of wireless communication.
In wireless communication, data from the primary source of revenue for the user associated with the radio masts. Mobile phones are devices that people can be seen more quickly reach a wireless telecommunications device to another.

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.

Technology can help older people stay in their homes and improve security, medical surveillance data and improved communication and social contacts. Mobile phones for older people have more buttons and better sound quality and amplification designed. For people with severe hearing impairment, stirring in his bed last night.
Health Technology
Telemedicine is the term used for health care will be through the Internet and other communication technologies available. Some programs use Internet technology to reduce social isolation of older people are forced into the house. A public-private partnership in New York, for example, older people with computers and Internet technology at home. The Senior Center uses virtual technology to improve social relations and access to housing with services for seniors in the community.
Independence Technologies
A number of universities and companies face the challenge of developing technologies that improve the lives of older adults. His innovations can help older people maintain their independence and parenting.
The new technologies described in this document is to improve the lives of older people and people need to help other states. With increased security at home and other important information about internal controls and improve communication and social interaction, aging, older people stay in their homes longer.
