VoIP Requirements List

admin — Thu, 25 Mar 2010 05:50:57 +0000

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 Tutorial

admin — Mon, 08 Mar 2010 08:47:49 +0000

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

admin — Mon, 01 Mar 2010 21:31:52 +0000

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.

VOIP Services Offer Numerous Advantages

admin — Fri, 01 Jan 2010 23:07:37 +0000

You may have heard of a new technology called Voice Over Internet Protocol, or VOIP for short, but you may not be aware of the potential that it has to change the way you use your telephone. That’s because until relatively recently, VOIP has been relatively obscure and not particularly easy to use. That’s not the case now though, thanks to the efforts of a number of companies that have refined VOIP technology and adapted it for everyday use.

In its simplest form VOIP is a technology that takes advantage of the fact that data can be transmitted long distances over the Internet without the fees that conventional telephone companies charge for long distance voice communication. This technology essentially converts speech into data that can be streamed over the Internet and then converted back into speech on the other end. The process goes both ways and is compatible with existing telephone networks.

The newer VOIP services have refined the technology to the point where it’s easy for everyone to use and offers plenty of bonus features that make it convenient for local calls as well as long distance calls. For example, when VOIP technology first became available, a computer with a microphone and speakers was necessary to use it. You could generally call someone using another computer for free, but if you wanted use it to place a long distance call to a normal phone line there was a small per minute fee. Now, all you need is a high speed Internet connection and a special router that your normal phone can be plugged into. While you can still use a computer to place calls using VOIP technology, calls can still be made without your computer being on, and you really don’t need a computer at all!

One great way that most VOIP services provide more value is by including all of the convenient features that are offered by conventional phone companies in there service plans at no extra charge. This alone saves you money above and beyond what conventional phone companies would charge for the same services. These services include voice mail, caller ID, call waiting, call forwarding, and a lot more. Best of all, you can control how you uses these services just by making changes to your account on the service’s website. You can use your computer to access voice mails, determine how you want to be informed of new voice mails, block the phone numbers of telemarketers, deny your caller ID information to people who you’re calling, block calls from numbers that don’t provide caller ID information, and much more.

There are also extra features that VOIP service can provide that are worth paying a little extra for. For example, you can get extra lines added to your account. These extra lines can be business and personal lines just for you, or one line for each member of your household. Each line can also be assigned a different ring tone, so that when they all ring though to the same handset, it’s easy to tell which line is being called just by the way it sounds. Your phone lines can also break the rules of how phones work by each having different area codes. That way if you have friends, family, or business clients concentrated in area codes other than your own, you can make it cheaper for them to call you. If you have a business, it might also be worth considering adding a toll free number.

There are so many options when it comes to VOIP technology and services, the only way to learn about them all is to go ahead and sign up.

The Aim To Standardize VoIP Protocols

admin — Fri, 01 Jan 2010 01:57:17 +0000

Voice over Internet protocol (VOIP) is a remarkable technology that lets us talk to one another from our home computers. It provides an efficient and flexible way for us to communicate at work and at home, and the cost savings versus conventional telephone services are incredible. It requires little upfront investment, and you have the ability to travel with your phone number all over the world. It is a technology that almost seems too good to be true. As with any relatively new technology, though, there are technical kinks with VOIP that continue to need refining and development in order for the technology to reach its fullest potential as a replacement for the current telephone systems that we are accustomed to using.

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.

VOIP Technology Saves Money and Increases Flexibility

admin — Sat, 26 Dec 2009 20:45:23 +0000

Computer technology- and the Internet in particular- is changing the way we conduct out lives in some pretty dramatic ways. One of the most dramatic changes that the Internet has brought us is the ability to take more control over how we communicate with each other by telephone and how we spend our money on phone service.

The specific technology that allows this is called Voice Over Internet Protocol, or VOIP for short. Voice Over Internet Protocol takes advantage the fact that data moves across the Internet without any of the constraints of conventional telephone calls when it comes to geography and distance. Just like you can send an email to anyone, anywhere in the world and download a web page from anywhere in the world without incurring long distance charges, Voice Over Internet Protocol technology allows you to call anyone in the world either without long distance fees or with sharply discounted long distance fees. Basically, VOIP converts both ends of a phone conversation into data that can be streamed back and forth across the Internet without any loss of sound quality or noticeable time lag. This revolutionary technology also makes it possible to for users of VOIP to call phone numbers that don’t use VOIP technology as well as the other way around.

VOIP technology has actually been around since the late twentieth century. In those days though, the service was rather limited. For example, calls were only made using computers and, though calls between users of VOIP services were free, there was still a long distance charge for calls made from a VOIP user to a conventional phone number. Users of VOIP technology still saw the benefit of the service when calling conventional phone numbers in the form of reduced long distance rates.

Now there are a number of services offering calling plans based on Voice Over Internet Protocol technology, including well known companies like Verizon and Vonage, as well as lesser known companies like SunRocket and Lingo. While there is a fair amount of variation in their services, these companies have a lot in common, including the improvements that they’ve made over the original VOIP services. Generally, these modern VOIP services offer free long distance inside the United States- often with Canada and Puerto Rico included- to any phone number whether it’s conventional or one that also uses VOIP. There’s still a long distance fee for most international calls, but most services will waive that fee if the number you’re calling uses the same service. Another big improvement over the original services is that most of these newer companies will let you use your own phone rather than a computer.

In fact, in most cases, you don’t even have to have a computer at all! Although a computer is helpful for changing account settings on the service’s website and you can still make phone calls from a computer, all you really need is a high speed Internet connection and your own phone. The service will supply a special router that plugs into your Internet connection and that you can, in turn, plug your phone into. Such a set up is also very practical in the sense that allows you to use your phone just like you would with a conventional phone line. Both DSL and cable high speed Internet connections are ample for this service, but if you happen to have a cable connection, you can save even more money by getting rid of your phone line completely. Most VOIP services add even more value by providing all of the features free of charge that you would ordinarily pay extra for from a conventional phone service and charging a monthly rate that’s equivalent to- and often lower than- a basic phone line from a conventional telephone company.

If you’re looking for a flexible way to keep in touch while saving money, then VOIP may be exactly the technology that you’re looking for.

Devices Based On VOIP Technology Provide Plenty of Communication Options

admin — Fri, 13 Nov 2009 18:44:15 +0000

You may have heard about VOIP technology- after all, it has been around for almost a decade- but if you haven’t taken a good look at the services that provide it these days, you probably aren’t aware of the benefits that it can offer you. That’s because there have been a whole slew of companies that offer VOIP calling plans with lots of extra features that are designed to save you money.

For the uninitiated, VOIP stands for Voice over Internet Protocol and it takes advantage of the fact that there aren’t any long distance fees placed on data as it moves across the Internet. VOIP technology streams telephone conversations back and forth across the Internet without any loss of sound quality or even a noticeable increase in time lag. In fact, conversations using VOIP technology can be clearer than those using conventional telephone technology. As a result of this set up, you can make local as well as long distance calls for free. Even international calls can be made with sharply discounted rates.

One of the major ways that modern Voice Over Internet Protocol services have improved upon their forebears is in the equipment that they provide to their customers. It used to be that the only way to make a VOIP phone call was by using a virtual telephone on a computer that was hooked up to a high speed Internet connection. Now, while the high speed Internet connection is necessary, and phone calls can still be made over computers, the computer itself isn’t really necessary. That’s because modern VOIP services can provide you with special routers and adapters that can plug into your high speed Internet connection. Once that’s been done, you can then plug your conventional telephone into the adapter and use it exactly like you would with a normal phone line. Because most of these services give you the option of logging onto their web site to make changes to your account- like initiating call forwarding, blocking numbers, accessing voice mail, and the like- a computer is very helpful to have with this service, but by no means necessary.

Other types of equipment that are out there and will allow you to take better advantage of your VOIP service include special phones that combine adapters and the actual hand sets of the phone. One company even offers a model that consists of an adapter/router, two charging bases, and two cordless hand sets. Once the adapter/router is plugged into the Internet connection, the charging bases for the handsets can be placed by any outlet in your home or office without having to worry about the location of phone jacks.

There’s also equipment available that will allow you to make your VOIP service portable. For example, most adapters are small enough to travel with you in your luggage and can be plugged into any high speed Internet connection so that you can make and receive phone calls using your own number no matter where you are in the world! If you want even more portability, you can get a key chain USB device that can plug into any Windows computer with a high speed Internet connection and turn it into your phone. It even comes with a microphone and ear piece. There’s also a handset that can be used to make and receive calls in any wireless hot spot.

These are just a few of the types of special devices that can make subscribing to a VOIP service more practical and flexible.

Internet Telephone VoIP (Voice Over Internet Protocol) – Technology and Terms

admin — Thu, 29 Oct 2009 16:21:25 +0000

If you are just starting to look at VoIP (Voice over Internet Protocol) as an alternative to conventional POTS (plain old telephone service) for your home or office, you will be hit with an all new set of technical terminology and industry jargon. This is a guide to help clarify and define some of the basic vocabulary used in the VoIP world.

Many of these terms are not limited to the VoIP world. As with so many technologies that revolve around broadband access, wireless networking and telephony, you will see these terms elsewhere so it will be helpful for you to understand their meaning as they relate to VoIP.

Telephone Adapter – In the world of VoIP, a telephone adapter is a device that is installed between your network and your telephone hardware. You can think of it as a converter as it sometimes referred to by this term. The most simple of these devices have three connections: power adapter connected to a power outlet, a 4-wire telephone connection where you plug in your conventional telephone hardware and an Ethernet adapter to connect the device to your network. The adapter converts (digitizes) the analog phone signal to an IP protocol.

Codec – Short for coder/decoder, this is a compression and decompression utility that digitizes and compresses the analog voice signal created by your telephone. There are a number of different codecs used and each one offers differing levels of compression. With varying levels of compression come different levels of quality of voice over the line.

VoIP Service Provider – This is a provider of the actual connectivity of your VoIP hardware, your network and the rest of the world. Some provide only computer-based services while others provide complete home or office solutions including multiple phone numbers and fax/data solutions.

RTP – Real-time Transport Protocol is the protocol used to specify standards for carrying voice calls over broadband connections. RTP is used in conjunction with RTCP (Real-time Transport Control Protocol) to provide QoS (Quality of Service) support. This provides a precedence or ‘right-of-way’ traffic control of voice calls over standard traffic over the network. Standard traffic can be thought of as text, email or other low priority, non-time sensitive traffic.

SIP – Session Initiation Protocol controls the way VoIP traffic is transmitted and routed over a broadband network. In simple terms, SIP is the standard by which a session (phone call) is initiated and terminated (phone hangs up).

VoIP phone – This is a telephone that is designed specifically to be used with a VoIP service. It has the functionality of both a telephone in its basic design but incorporates all the functionality of a telephone adapter making is a single, self-contained VoIP device.

Softphone – This is actually a misleading term in that it is not really a phone at all. A softphone is a computer that is equipped with a microphone, a speaker (or headset) and a software program that allows you to make telephone calls without the need for a conventional telephone or adapter.

Mobile Phone Contract Plans With VOIP

admin — Fri, 16 Oct 2009 16:02:27 +0000

Introduction

The revolution of internet communication is here to stay for a very long time and this is primarily because it has done so much to help people by its mere presence alone. The voice over IP (VOIP for short) technology that has hit the market by storm over the last couple of years has now expanded to be a major competing technology in nearly every major branch of communications.

The VOIP revolution has been so fast and so fierce that even the most established conventional telephone companies are now rushing to create VOIP infrastructure that they can provide to their customers so that they don’t end up losing them to other companies that are on the cutting edge. To that end, even mobile phones have been created that have the ability to use VOIP or a similar piece of technology in order to accomplish the same task.

The Mobile Phones

A question that very many people have when they initially here about the recent expansion into the mobile phone market has to do with the technology itself. While it is easy to understand how VOIP technology works on a conceptual level (i.e. the internet connection being used in conjunction with specialty software to facilitate communication in a manner similar to that of a telephone) for normal, land-based systems it is a lot more difficult to understand exactly how it works in the sense of a mobile phone solution.

If you have ever traveled on a plane before, you have more than likely seen a business person utilizing their internet through the use of mobile internet technology. This type of technology has been around for a very long time and all of the major businesses make sure that their correspondents have access to that kind of technology when they are on the move.

Wherever you have the ability to connect to the internet and therefore generate an internet protocol address, you have the ability to use the VOIP technology. This is ultimately how mobile VOIP services are utilized and because of the boom in the market many of these technologies are available for personal use at very reasonable prices.

Advantages

There are many advantages to using a VOIP mobile phone contract and the one that is largest in the eyes of many people is the price. The reason that conventional VOIP became such a popular service was that it was quite a bit cheaper than conventional telephone plans when it came onto the market. In similar fashion, a VOIP mobile phone contract is going to be quite a bit cheaper than the conventional mobile phone contract you have right now.

This decrease in the price has allowed many people the chance to save some money each month and when a person is able to save money without a reduction in quality, they quite obviously are going to become a very loyal customer. The ability of VOIP services to generate a large number of very loyal customers in a very short time is ultimately what has made many companies move a large part of their communication operations towards developing and promoting VOIP technologies.

Things You Need to Know About VOIP Technology

admin — Sun, 11 Oct 2009 16:28:06 +0000

VOIP is the buzz word everywhere and it is time you understood the VOIP technology and why it is usurping the traditional telephone system. VOIP is an acronym for Voice over Internet Protocol, or simply stated, it is phone service over the Internet. If you have a broadband Internet connection, you can then get phone service delivered through the Internet connection instead of the local phone company.

You must know how different will the VOIP technology be over your conventional telephone system. There are, of course, a lot in common, but there are also some decided advantages that VOIP technology offers. VOIP will facilitate local, long distance and international telephone calls over your high-speed internet connection at incredibly low rates. VOIP technology is constantly getting updated and there are a lot of new features getting added.

Few of the attractive VOIP telephone system features are – voice mail, three-way conference, speed dialing, call forwarding, simultaneous ring, call waiting, caller ID, call return, caller ID block, anonymous call rejection, do not disturb feature, and last number redial. This is not to speak of the tremendous cost savings you can enjoy by switching over to VOIP.

An IP address identifies each IP phone, and it is known by this IP address regardless where it is plugged in. The only thing required would be a broadband connection. This makes the system both portable and flexible.

If you use VOIP through a PC-to-PC connection, then your calls are free anywhere, as long as, the receiver of the call also has VOIP. Further, most VOIP providers offer unlimited calling plans for calls made within a certain area, for single monthly fee. Whatever the use, one thing is abundantly clear – traditional phone service is much costlier. Most VOIP service providers also offer extra premium services such as caller id, without additional charges.

This is not to say that VOIP has no demerits. As a matter of fact, there was a recent press release stating the technical review conducted by the British government has found several security flaws in products that use VOIP. There is also concern that the VOIP does not full support its own encryptions yet. Thus it will be easy to eavesdrop on VOIP telephones and to even alter what is spoken.

Another major problem with VOIP is that it is run by power and if there is a power outage, your communications will come to a standstill. This is unlike traditional phone service, where you can still use your phone without the aid of electricity. Voice quality of VOIP is certainly efficient under normal conditions, but when you run into high traffic times in cable broadband, it could affect voice quality.

There is no denying that VOIP still has some drawbacks to be ironed out. You may exercise your discretion whether to go in for VOIP technology now or wait for some more time till these limitations are removed. It is reasonably expected that sooner than later, the research wing of the company will address these shortcomings and perfect the VOIP technology. But in the ultimate analysis, VOIP’s benefits outweigh its negatives and it is for the intending buyer to study the pros and cons and make an informed decision.
