Voice over Internet Protocol, or VoIP as it is commonly called, is a revolutionary technology that has created an upheaval of sorts in the domain of long distance communications. End users can now use their personal computers to talk to friends and relatives – who could be located in another part of the globe. A reliable broadband connection is used for the purpose. The need for conventional telephone lines can be done away with; low cost calling made available through IP telephony solutions is increasingly taking the place of traditional phone networks among residential as well as corporate users.
However, certain requirements need to be met for the most satisfactory use of this high-end technology. The equipment used, for one, has to be of the highest quality. Broadband connection in a computer is necessary for good audio quality, for instance. The experience can also be optimised using PC speakers and microphones.
A basic VoIP requirements list has to be in place for users to make the most of the VoIP phone services. As is well-known, the flexibility of voice over IP makes it more user-friendly as compared to traditional telephone networks. Users are able to make quite a few calls over a single connection. A stable Internet connection is all that is needed – and one can make calls from almost anywhere in the world. Innovative features include video integration, fast and efficient exchange of data files, and audio conferencing. Quite a few security features are in place; and users can be sure of security of their calls. Other functionalities found in PSTN networks are also found in IP telephony. These include caller ID, automatic redialing and call forwarding. And with the latest trends in technology, it has become easy to make VoIP enabled calls through mobile devices as well.
VoIP security is not that difficult to implement. Quite a few voice over IP solutions are supported through encryption which make them very much reliable and user friendly. Security is also implemented through patented audio codecs and compression techniques.
Moreover, one should ensure that the broadband connection through which the calls are routed are not congested. This rules out voice drop-outs and long delays.
One can say that the VoIP phone is perfect for quite a few people – from frequent travelers, bored housewives to high-end professionals and busy executives. People who are not near to any fixed line phones or who are traveling the world find these solutions very much affordable and easy to use. With prepaid VoIP phone cards easily available in the market, there are no problems involved in making such calls.
However, when using VoIP products or subscribing to a VoIP service, users must make some provisions against untoward circumstances such as power failures and the services of broadband carriers going down.

VoIP Requirements List

VoIP or voice over protocol is one of the latest innovations in communications technology. The main difference it has with the old telephony system is that it uses data packets while the old telephony system uses switch boards.
In case you are not familiar with switchboards, imagine your call being routed to an operator before it reaches the person you are calling. That illustrates how a switchboard works. VoIP uses data packets that are sent and received via the internet. Hence, the basic equipment you will need to enable VoIP is a modem because this is the main device that allows you to get an internet access.
VoIP products come as trunk or hosted. If you are still wishing to use your old telephone device while utilizing VoIP at the same time, you will need to purchase a gateway from VoIP vendors. The gateway comes in a data packet that looks like a box. You would have to connect this to your conventional telephone or fax machine to enable VoIP. However, if you have an IP enabled system, there is no need to purchase the gateway.
There are four ways by which you can make the calls using the VoIP. These include internet-internet, phone-internet, internet-phone, phone-phone. If you are making a call towards a phone, it can be a regular, non-VoIP phone. Otherwise, the recipient of your call also needs to have a VoIP-enabled device. If you are making a call through a computer, you need to have a head set and a VoIP software program. If you are making an internet-internet call, the computer you are calling to must also have the same software as you have. Examples of this software are Skype, that of Yahoo, MSN, etc.

VOIP Problems
March 1st, 2010
VoIP is a means of telephone service made available through the ever-expanding popularity of broadband internet service. VoIP (or “Voice over Internet Protocol”) services enable users to call extremely long distances over the World Wide Web without accruing large conventional long-distance telephone fees. In order to use VoIP, customers must have an existing broadband internet connection in place. The VoIP carrier provides a new phone number, access to the service, and for an additional fee, the phone equipment as well. While companies such as Vonage and Skype helped pioneer the industry by making people more aware of the technology, large conventional telephone carriers are also stepping up in order to offer their own VoIP services, proving that the technology is maturing. However, despite the large backing of major telephone carriers, VoIP still isn’t perfect.
The most notable of existing VoIP problems is the lack of an adequate infrastructure and effective back end system. Though as the companies and divisions that are devoted to VoIP services implement increasing usable standards in place this aspect grows less worrisome. However, in the beginning, billing issues as well as IP concerns had some companies, particularly those that specialized in conventional phone services, reeling.
Another large weakness that VoIP exhibits when compared to traditional home phone service is that VoIP is reliant on a broadband connection (dial-up internet is too slow), service up-time, and power, whereas a traditional phone service combined with an older, powerless phone needs none of them. While broadband internet service has become much more reliable in recent years, it is still not as dependable as conventional telephone lines. This means that if there is a problem with internet service, there will be no telephone service as well. While this can be very inconvenient for home use, it can be downright devastating for businesses that find themselves in a situation with no phones. Additionally, the unavailability of telephone service during a power interruption can leave people stranded with no phone service during emergencies, which can have life-threatening consequences.
Finally, the quality of phone calls that VoIP services offer can range from very good to very unacceptable. While many customers rave about their clear service, others regularly complain of dropped calls, strange sounds, delays, and echo. Delays are commonplace in VoIP phone calls and many expect the problems to become worse before they get better because, as with anything else on the internet, VoIP calling is subject to hacking. Therefore, companies will be scrambling to implement security patches in place, possibly at the sacrifice of quality, at least at first.
However, even though VoIP may not be as reliable as traditional telephone communication just yet, there really should be no surprise. Traditional telephone services have had the better part of a century in which to perfect their networks and it still isn’t perfect, either. For the cost, VoIP cannot be beat if you have a contingency line in case your power or broadband goes out. If you already have broadband internet service then the equipment and monthly VoIP service fees should be affordable enough to utilize the service in spite of its flaws – which are only going to become minuter as the technology matures.
