A VoIP phone allows real-time communication through the Internet. It can digitise the sound of a human voice so that it can be routed through the net. The development of this technology began way back in the early 1980′s when developers were looking for ways to communicate with each other via their machines. The technology was then adapted by the some technologically savvy sections of the business community who used data networks to route voice traffic.

However it is the growth of low-cost broadband Internet access that has really fueled the spread of Internet telephony and brought it into the mainstream. Anyone with a high-speed Internet connection can now use VoIP technology to make what seem to be very cheap calls.

In addition to these cost savings that a VoIP connection offers, there are other factors that make this technology so attractive to users. The versatility and flexibility of VoIP are examples of this. The software is location independent. So it is possible to relocate your home or business without having to change your phone number. With a USB VoIP phone you are able to make and receive calls on a laptop whilst away from your desk or use a wireless VoIP handset for calls in a public hotspot.

Ease of use is another reason that people have been attracted to VoIP. Users can often be put off from using new technology if they find that it looks difficult to use. This issue has been addressed by the developers and the era when Internet telephony was the domain of the geek is long past. Nowadays all anyone who wants to make a call has to do is pick up and dial. It really is as simple as that.

There are now a wide range of VoIP services available that would suit both business and home users. New services are being made available by service providers as the market continues to grow. As things stand VoIP stands alongside the traditional telephone network for reach and in many ways outshines it for versatility. Internet telephony looks set to continue to be one of the fastest-growing applications on the Net.

I hope that this article has given an insight into VoIP technology and the reasons why it is replacing the traditional telephone line in many offices and homes. Want to join the Internet telephony revolution? It’s your call!

The USB VoIP Phone is easy to operate and configure for Home and Office

The goal of SIP was to provide users with many of the functions and features they typically expect with making phone calls, such as familiar rings, hearing the ring back tone when a call is placed, and the process of dialing a number. SIP goes beyond this however, also implementing a number of advanced features. Despite its’ convenient interface that mirrors that of a typical telephone call, SIP is based on an internet protocol rather than that of the telephone industry. Because of this, SIP is able to work seamlessly alongside other internet based protocols. This has allowed the technology to uniquely establish a user location, meaning that you can tell the IP address or “location” from which a person is making a call, something vital for offering emergency services. It also allows for coordination amongst the various participants in deciding upon what call features will be supported, as well as providing the protocol for call management which allows for adding, dropping, or transferring call participants.

One of the most exceptional benefits of Session Initiation Protocol (SIP) is its application with Private Branch Exchange (PBX). A private branch exchange is a private telephone network used within an enterprise in which users share a certain number of outside lines for external telephone calls. This provides a significant cost savings to the company because it allows companies to quickly and easily make calls within their institution, as well as save by limiting the number of external phone lines that must be maintained. SIP can extend these cost savings dramatically by offering users free long distance calls worldwide. Once again, because SIP is internet based rather than running over traditional telephone lines, the cost of call transmission are as cheap as say sending an e-mail, that is to say, Free! While PBX is already an efficient use of office resources incorporating SIP into a PBX means taking such savings and capabilities to a new level. Incorporating SIP gives users’ access to free interoffice communications, long distance calls, as well as huge savings in setup and transaction costs. These transaction cost savings are due to the fact that SIP is based on internet protocol allowing for the ability to physically move phones without any need for rewiring or new setup costs. Because that the system is peer-to-peer rather than cog and wheel like hardwired telephony means that there is no complicated setup necessary, but rather users can simply plug the phone into any available broadband connection and without the need for any complicated hardware or software, calls are ready to be made and received.

This brings us to what is potentially the greatest savings that SIP provides. We all hate to have to pay $2.00 for making a simple local call from a hotel room. But for those of us that have had to pay exorbitant long-distance charges from hotels, the level of angst felt reaches new heights. Add to this the fact that often companies require conference calling for their employees, a service that hotels are all too happy to charge a high premium to provide. For companies that have a lot of their employees traveling or practicing in various locales, the overhead costs of making such calls can really put a damper on year end profits. SIP offers a solution to hotel bills, and for that matter all telephone bills whatsoever. Just as sending an e-mail is free whether you are sending that e-mail to a person across the street or around the world, so making a call using SIP from any locale to any other locale in the world is free. All that is needed is a broadband connection. And just as one can send an email from wherever the internet can be accessed, SIP users can make their free calls from the office, the home, or even (gasp) the hotel room. Not to mention the huge savings in regular long-distance charges, the simple fact that long distance and local calls can be made for free from hotel rooms (most of which offer complimentary broadband service) is an enormous long-term cost savings. But add to this the fact that conference calls are available at no additional cost, which can be explained by following the principle that sending an e-mail to many individuals at the same time is just as cheap as one to one communication. Altogether these savings mean that companies who have in the past been laden with high local and long distance phone bills will be able to have their employees keep in close communication no matter their location for free.

SIP goes beyond this, however. Because SIP uses peer-to-peer connections there are no extra costs for having hundreds or even thousands of employees making SIP calls whereas the management costs for such a system under traditional telephony would be astronomical. This is never the case with PBXs that utilize SIP in a peer to peer connection format, however, where structural costs do not increase as your business grows and your usage of the PBX increases.

Session Initiation Protocol (SIP) offers customers of traditional telephony fantastic cost savings, the flexibility to make free calls from anywhere in the world at any time, and the ability to expand a PBX system with no setup costs. Because there is no complicated hardware or software necessary to setup SIP in a PBX, implementing the technology is as simple as having access via broadband to the internet. Due to these benefits as well as innumerable others, expanded use of SIP in PBX and in a variety of other settings is simply a matter of expanded customer exposure to the possibilities of SIP.

(P) Portability:

Firstly it may be stating the obvious, but people buy laptops because they can take them anywhere. Office workers need no more be confined to their claustrophophic cubicles. Instead those statistic charts and data reports can be compiled on a train, in the comfort of an arm chair, or even on the beach! Portability equals flexibility, but alas this hasn’t always been the case. Today’s ultra portable laptop computers have a come along way since the bulky, sewing machine sized machines of the late seventies and early eighties. Indeed one of the first portable computers was built by IBM, and this machine (IBM 5100) weighed in at a hefty 50lbs! Today’s corridor warriors would have trouble lugging that puppy from meeting to meeting, unless of course they subjected themselves to an intensive dose of steroids

(V) Value:

In the seventies the aforementioned IBM 5100 would have set you back a staggering 20,000 dollars. Today a top of the range IBM Thinkpad can be bought for around 3000 dollars. Cheaper Thinkpads can often be obtained for well under a thousand dollars, especially if you don’t mind purchasing a used or refurbished model.

(P) Performance:

Many laptops today come fitted with Centrino processors which offer superb performance and improved battery life. What is Centrino I hear you ask? Well this is Intel’s name for their new notebook technology that combines their Pentium M processor, 855 chipset and the Intel PRO/Wireless 2100 Wi-Fi 802.11 network interface. Laptops fitted with these processors are usually lighter because of the smaller components used.

Couple this attractive feature with wireless networking technology and you have a powerful technological package. Wi-Fi is short for “Wireless Fidelity” and it’s usage is growing quickly amongst home users, office workers, even coffee shops. If you enter Wi-Fi areas with a properly equipped notebook, you can access the Internet at broadband speeds.

Tom Fox writes for the Cheaper Laptop – a site dedicated to offering relevant news commentary and reviews about cheap notebook computers and netbooks. Let’s say thanks to VOIP business providers

At the beginning of a VOIP phone call, there is an analog phone (in use with an ATA), an IP phone, or software that converts data from analog to digital and routes the call to an endpoint. Along with these pieces of equipment, there are protocols that are employed to get the job done efficiently. A protocol is a set of rules that control data transfer between two points, in this case, from the placement of a phone call to the destination. Protocols are put into use by any combination of hardware and software to define real-time communications performance.

There are several VOIP protocols used at this time that mark out which programs (that transform the data) connect with one another along with the network. The most common protocol being used for VOIP is know as H.323, which was created by the International Telecommunication Union for the purposes of videoconferencing. This protocol is actually a group of several specific protocols that provide provisions for videoconferencing, data sharing, and audio transmission (VOIP). However, since it was not expressly designed for VOIP, there are often compatibility issues with its use.

A newer protocol has come out known as Session Initiation Protocol, or SIP. SIP was developed specifically for VOIP, and it is less complex than H.323. Yet another protocol used for VOIP is known as Media Gateway Control Protocol (MGCP). It focuses on destination control, and is intended to be used for supplemental features such as Call Waiting. A big problem arises because these three protocols do not always work together very congruently. This is often a problem when placing VOIP calls between different networks that use different protocols. And since there has not been yet developed a uniform set of standards for protocols to use for VOIP, problems are likely to continue until they are established.

Despite the technical glitches that can be encountered in using the technology to place phone calls, VOIP is still far more efficient, accommodating, and cost effective to what we are used to in telephone communications. The direction in which VOIP is heading hints that it is poised to one day replace our traditional telephone technology altogether. As with any technology-driven product or service, developers of VOIP will likely continue to improve upon current standards of VOIP and its protocols, further improving the technology for widespread use. This will provide users of VOIP even greater efficiency and reliability when they want to make a telephone call.

In simple terms, computer systems are complete computers with all the necessary hardware and software components working together to perform correctly. A casual user will likely hear the term and associate it with laptops and desktops. They wouldn?t be wrong with this assumption, but like so many other things in the industry, there is a lot more to it.

The full purpose of most computer systems is to deliver the satisfactory completion on the tasks you need it for. And with the wide range of systems available, from laptops to desktops to netbooks, you can easily find the one you need if you take the time to research the available options.

There are also computer systems analysts out there that can examine all the machines available and list the pros and cons of each. A consumer can look to these reviews or do other personal research to learn what systems will likely cover all their needs.

Despite benefits there definitely exist disadvantages. Most system manufacturers are aware of this and seek to always improve their products through research and development. They have developed things like anti-virus protection programs, and restorative software, in case of crashes and an accidental virus in your computer.

Although these systems are mostly geared towards offices and home use, there are portable computer systems specifically designed for outdoor use, and any harsh environment. You can feel confident that your purposes will be completed efficiently and productively, even in the most unorthodox of atmospheres.

As progress in technology continues to be made, computer systems are being created to be flexible, compromising, and available to the masses for any and every use. New software and applications continue to push the boundaries of what we can do, and the hardware evolves accordingly.

Computer systems are tools that are relied on more and more as time goes on. As the dependence on computers increases while business, schools, and even shops and stores use them, going through life without these systems seem almost primitive, and difficult. Looked to for organization of data, storing of information, and quick and precise results, these systems are nothing short of a necessity for everyday activities and the constant advances of technological knowledge.
