How VoIP Works — Busting Out of Long Distance Rates

admin — Fri, 26 Mar 2010 22:05:32 +0000

VoIP is the newest advancement in audio communications technology, and has a
variety of different applications that make it useful. VoIP stands for Voice
over Internet Protocol, and how VoIP works is actually quite revolutionary
because it streamlines the process of sending analog audio signals by converting
them to a much easier to send digital form for transmission.

To understand how VoIP works, you’ll need to understand the basic concept
behind regular analog audio communication as well, since this is the precursor
for VoIP. Analog phone calls are actually made via fiber optic networks by
digitizing your voice communications for sending the signal across thousands of
miles, but once it gets to the final destination (a home or office phone, for
instance), the signal is once again converted to analog.

During these calls, the switches remain open even while there is dead air and
no conversation is taking place; the circuit is also open in both directions
even when only one party is talking and the other is listening. This isn’t
terribly efficient, and slows down the communication of information
considerably.

Packet switching streamlines VoIP

VoIP works on a different premise — rather than circuit switching, data
packet switching sends and receives information only when you need it instead of
in a constant stream. It also sends the information packets along whatever open
channels are available rather than a dedicated line, which is much more
efficient. The information is simply reassembled at the source.

The payload of each packet has a destination coded into it determining the
ultimate destination. When the computer at the other end receives all of these
packets, it will reassemble the information into useable form. This form of
sending audio data is extremely efficient because it always takes the cheapest
route that is also the least congested.

The compression of information and use of multiple routes in order to send
that information over the most efficient route makes sending audio over packet
switching quicker, much less expensive and more efficient. The number of calls
that can be sent is orders of magnitude higher than it was with the more
traditional analog circuit switching systems.

For companies, the savings in long distance charges can be in the hundreds or
even thousands of dollars per year. If companies also make extensive conference
calls, VoIP makes even more sense when combined with conferencing options such
as document sharing in systems offered by companies like Voxwire and iVocalize.

Different types of VoIP calling are available

The most commonly used VoIP system is from one computer to another. To set up this type of service, you will need to have a sound card installed in both computers along with microphones and Internet connections. For practical purposes, you’ll want a broadband connection or DSL — a dial-up modem will be so slow the sound quality just won’t be that good. Aside from that, all you need is a software package that can set you up with everything you need to use VoIP to make phone calls to whomever is also set up with the same system. You can also invest in IP phones if you want something that looks just like your standard analog telephones but with VoIP connectability. These simply replace the old-style RJ-11 connectors with Ethernet connectors (RJ-45). Hardware such as routers and the needed software are built right in. Analog telephone adaptors (ATA) enable you to connect a standard telephone to your computer Internet connection in order to take advantage of VoIP options. ATA converts analog signals to digital so that it can be transmitted properly via the Internet. The newest option on the market is the Wi-Fi phone, which uses short-distance Internet transmission of VoIP to replace cell phones calls. Wi-Fi broadcasts over the radio spectrum to cover short range areas for users in certain areas, and these “hot spots” have popped up across the U.S.

The upshot of VoIP is that standard long-distance charges may soon become a
thing of the past. As more and more consumers turn on to VoIP and broadband
connections make it easy and inexpensive (as well as practical) to make phone
calls over the Internet, fewer individuals will be willing to pay high rates to
make a telephone call they can make for free or next to nothing via their
computer.

VoIP saves you money on long distance

There’s no by-the-minute charges with VoIP, no set-up fees, and no “time of
day” or overages. That’s the great thing about VoIP plans. You just pay a
monthly fee and get to make all the calls you want over your computer for one
monthly fee. It’s so simple and elegant, and it’s the solution that everyone’s
been wanting and waiting for far too long.

You don’t have to wait for a certain time of day of day of the week to make
telephone calls with VoIP. There’s also the advantage of being able to use your
VoIP connection from anywhere — remember, you’re not tied to a phone jack to
use your number, but an Internet connection, so you can call from anywhere with
many calling plans.

Some of the companies that offer excellent VoIP plans with unlimited calling
are listed below with their most popular options:

Vonage currently offers a $24.95 per month unlimited VoIP package to anywhere in the U.S. or Canada. It includes voicemail, call forwarding, three way calling, call waiting and caller ID. Packet 8 can provide unlimited VoIP for $19.95 a month in the U.S. and Canada with a variety of features like call waiting and three-way calling, and can also give you video phone service for about $29.95 per month. AT&T’s CallVantage provides the usual U.S. and Canada broadband calling with voicemail, call waiting, etc. along with email, a call log and a ‘do not disturb’ option, all for $29.99 a month. You also get to keep your phone number for life, no matter where you go — a great feature for some who move around a lot.

VoIP in web conferencing packages

VoIP is used in almost all web conferencing services as an alternative to
standard conference calls, and looking into these packages will give you an idea
of some ways to combine VoIP with extras such as white boards, document sharing
and video. For less expensive options, many companies can provide strictly audio
VoIP conference calls combined with text messaging and document sharing without
video.

Some companies that offer VoIP in web conferencing packages separate from
video conferencing are:

Voxwire offers voice communication with features like auto-queue, mute options, individual speaker adjustments and moderator controls along with a “follow me” browser system so that all participants can view a shared desktop. Two persons can use VoIP for $9.95 a month, or up to ten in a conference environment for $29.95 per month. VoiceCafé provides similar services with a wide range of options that vary from packages with VoIP capability for five people at a time on a conference call to up to 500 in one conference call, all for a flat monthly fee. The prices vary depending upon what package you choose, and there are several. iVocalize offers VoIP along with Internet conferencing options like PowerPoint presentation capabilities and presentation recording for future playback. They also provide optional Unicode translation in thirteen languages. The most basic VoIP package begins at $10.00 a month with a prices going up incrementally depending upon your needs and how many will be involved in your conference calls.

It is obvious that conference calling as well as standard long distance
calling will be changing greatly in the near future as VoIP changes the
landscape of telephone service. “Land lines” for long distance calling will
eventually become obsolete as broadband becomes more common and makes VoIP just
as commonplace as any other type of telephone call.

And with the greater portability of soft phone options built into laptops and
the use of ATA phone adapters, the use of VoIP in the average home will arrive
sooner rather than later.

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 Providers – How To Choose One

admin — Fri, 05 Mar 2010 16:22:51 +0000

When you’ve made the decision to move to VoIP phone, you’ll need to select a VoIP provider. The most well-known is Vonage, largely because of their aggressive advertising campaign. There are, however, several other VoIP providers that you should consider. A large marketing campaign does not guarantee good service.

Vonage is your basic VoIP phone service, with the emphasis on the phone. For a monthly charge, they send you a device to hook up to your phone that does two things. First, it digitizes your analog voice, a must for VoIP usage. Second, it initiates an internet link that runs through your DSL or cable broadband hookup. VoIP-specific phones are perfect to use on Vonage service, and you can use them wirelessly.

You get your local and long-distance phone service for the monthly flat rate, and also a number of services like three-way calling and call forwarding, which few people use. In some plans, you do pay for outgoing calls after a point, but the number of minutes you get before reaching that break point is pretty generous.

Skype is a very different sort of VoIP provider. It started as primarily a computer-based, not phone-based VoIP, and most people originally used headphones with their ordinary computer to access a Skype account. You can get Skype phones today that run through your computer, but most of Skype’s services are more web-friendly.

In addition to phone service, Skype has robust online and computer-based communications technology like chat and user lookups. But the outstanding feature of Skype is the price. If you’re using it to call directly to another Skype user, anywhere in the world, it’s free. It’s also the easiest VoIP service to take with you; if you have a Skype account, you can access it from your computer or any Skype-enabled computer, anywhere in the world.

Lingo is a new entry to the VoIP world, and is ascendant primarily because while it offers Vonage-style services, it also offers dirt-cheap rates. Vonage focuses primarily on the United States, Canada, and Mexico; Lingo’s area of expertise appears to be Asia and Western Europe, where it offers either unlimited calling or a robust calling plan. Unfortunately, they don’t seem to have worked out all their bugs, and Lingo does not have a stable calling platform yet.

AT&T CallVantage is another new entry, though it’s from an old company. They, too, are based on similar technology to that Vonage uses, with devices that hook up to your phone et al. Unlike Lingo, AT&T offers excellent quality service, as one might expect. At one point, AT&T had overly-complicated technology for hooking up your VoIP service, but they have improved and now aren’t much worse than Vonage.

No matter how good your VoIP provider is, your telephone stability and reliability when using this service is limited by your high-speed internet connection. If the power goes out, no phone. If your internet service is interrupted for any reason, no phone. If you are confident in your cellular service and aren’t worried about this, that shouldn’t be a problem, but it is something you must consider when you choose your VoIP service.

The bottom line is not to choose VOIP service based on price alone. Look at the features and determine how important that is to you and how often you will use it. Our web site features our Editor’s Choice Best Pick for the best VOIP service available based on a wide range of criteria.

How Does VoIP Work? Understanding The Basics

admin — Sun, 28 Feb 2010 05:17:01 +0000

How does VoIP work? Like many people, you may have already heard of VoIP. If you weren’t born in this decade, you may still wonder what it really is. What can VoIP do for you and how exactly is it useful?

Basic Concept

VoIP stands for voice over internet protocol. These days, it is considered an alternative to the typical method of communication involving telephones. Instead of using telephone sets that transmit analog signals, VoIP converts these signals to digital chunks. These are reconverted to audio data when it reaches the recipient. The entire transmission happens over the internet. Although VoIP technology is still far from being preferred and considered standard, some people think that VoIP will eventually replace telephones. It could very well be the next step in communications technology.

The Specifics

So how does VoIP work exactly? VoIP is best understood by understanding typical phone calls first. Regular phone calls make use of what is called circuit switching. When you make a call, your call is passed through a series of switches starting from your phone carrier. Once the other party answers the call, the circuit between the two of you is opened.

Instead of circuit switching VoIP uses packet switching. In this technology, your voice is converted to little packets of data. These packets of data come with their instructions of where they should be sent. They are then sent through a variety of possible routes. They take the nearest router and are passed on to succeeding routers until they reach the recipient. When the packets are received, they are reassembled into a form that can be understood.

Advantages of VoIP

VoIP can offer all the features and benefits of a phone service. Its advantage over traditional phones is that VoIP calls can be made from almost any part of the world. Wherever there is an internet connection, you can have VoIP. The technology can provide cheaper calls than standard telephone technology. This is mainly because VoIP does away with costly circuit switching.

Disadvantages of VoIP

VoIP can be fast, convenient and cheap. It has, however its own disadvantages. These disadvantages are basically due to: (1) the current reliance of present systems on telephone technology; and (2) the shortcomings that plague computer technology.

Telephone Connections – Such services for example as security and cable still rely on telephone connections. Unless the whole country or world agrees to switch to VoIP, these services are likely to stick to their old methods.

This is not the biggest concern though. Since VoIP relies on internet technology, it is also susceptible to the problems that confront the internet and computers. You can therefore expect such problems as viral attacks, crashes and stolen packets.

Now you know the basic answer to how does VoIP work. In reality, this piece of technology does hold a lot of potential. Like everything else, the old ways of communicating over long distances can change. VoIP is the first logical shift that can be taken. It may take a long time however, before VoIP can become a fully integrated and snag free system.

What You Need To Know About VoIP Broadband Telephone Service

admin — Thu, 28 Jan 2010 13:09:38 +0000

If you haven’t heard much about VoIP before now, you certainly will in the future due to its rapid emergence as a major communications technology. VoIP stands for Voice Over Internet Protocol, and it basically is the ability to make telephone calls over the internet to either a receiving computer or telephone.

For years standard telephone lines have used a circuit switching network to transfer telephone calls, but VoIP technology uses something called packet switching instead where audio is converted into packets of data that are sent over the internet and reassembled on the other end by the person’s computer or telephone. If a high-speed internet connection is used, a conversation can take place that easily compares to a regular telephone call in sound quality.

All of this may sound like a very new technology, but in reality it’s not. Programs that make use of VoIP technology were springing up on the internet more than ten years ago, although they were much less capable than those that are available today. Also every year continues to bring higher standards of quality for VoIP applications, and it will no doubt be a viable technology for many years to come.

A good example of the use of VoIP technology is instant messaging programs. If you have used an instant messaging program that is voice enabled, where you can communicate by audio, video and chat, it is in large part due to VoIP. This is because VoIP is able to integrate audio, video, data, e-mail, and more simultaneously. Although most consumers will use VoIP for telephone calls initially, many businesses are already finding expanded uses for VoIP technology.

Several telephone companies are realizing the potential for VoIP services and so companies like Sprint, Verizon, AOL and others are now offering VoIP plans to consumers. One of the distinct advantages of buying a VoIP solution is that it costs significantly less than most standard telephone services. In fact, most service plans will allow you to make unlimited long-distance telephone calls on your VoIP plan for very inexpensive rates. And the subscription rates are usually free of many of the taxes and regulatory fees that often accompany your local telephone bill.

Another major advantage of many of the current VoIP subscription plans that are available is that they often include extra features such as call waiting, call forwarding, three-way calling, voice mail and much more. Quite often, these extra services cost more when included by your local telephone service, but VoIP plans usually include them at no extra charge. Another interesting side benefit is that many providers will allow you to select a new area code and phone number for your VoIP calls, so if you have family or friends in a distant town, they can call you for free on a number that is local to them.

Hopefully this information on VoIP technology will help you understand more about how it works and how it can be beneficial for you.

VoIP Technology is Breaking the Chains of the Traditional Phone Companies

admin — Wed, 11 Nov 2009 12:41:22 +0000

Before companies like Magic Jack and Vonage we were slaves to the traditional land based phone systems. Big phone companies like AT&T and SBC (just to mention a couple) had us at a disadvantage and they knew it. With traditional land lines, every feature had a fee, even keeping certain features off you phone cost money. After adding up all those fees, along with your local and long distance, your phone service could cost $40.00, $50.00, $70.00 a month or much more depending of what features you tacked on and how many long distance calls you make a month.

Well I’m probably not telling you anything you didn’t already know. So how about something you may not know about – VoIP and companies like Magic Jack, Vonage and Skype are paving the way for this money saving communications technology. VoIP like Magic Jack and Vonage is finding their way into homes, not only here in the US, but around the world.

VoIP (Voice over Internet Protocol) – allows and analog signal from your phone to be converted into a digital signal that can be then be sent over the internet (much like a email) instead of over a wire network like the ordinary land line. This allows the user to make long distance phone calls for free or at a much cheaper price depending on the service used. Vonage is a pioneer and one of the most popular of this new telephony technology.

There is now a small host of companies offering VoIP services that will continue to grow as (VoIP) is the future of communications. Magic Jack is such a company and is growing in popularity as more and more people are becoming aware of this new technology. Magic Jack is the only service that has its own network system which is one of the most compelling reasons the service is so inexpensive.

While other VoIP companies are offering good products for reasonable prices, none can beat the price or can offer the simplicity and the flexibility of Magic Jack. The Magic Jack device plugs directly into an available USB port (2.0 or higher) the software in the device makes contact with the Magic Jack home base and after only a few minutes it takes to set up your account and phone number, you are ready to go. You can then take your phone that had been plugged into the land line wall mount and plug it directly into the Magicjack, lift the receiver, hear a dial tone and start making calls.

Companies like Vonage must pay for the network they use, so it comes with a low monthly bill. Magic Jack has one low price you pay annually which is less then one month’s bill of a traditional land line. Magic Jack will let you opt in for a multi year agreement that saves you even more money. Skype is another popular VoIP company that is much better then the traditional landline but has limitations such as phone calls are only free if you are calling other Skype users and must purchase credits in order to call someone using phone services other than Skype. This would kind of be like buying minutes for cell phones.

Magic Jack is not a phone or software installed on your computer; it is a device with the software installed in it that plugs into your computer or any other computer with a broadband internet connection. This means you can take the Magic Jack with you on long trips or even out of the country and make free long distance phone calls back to the US or Canada for free. How’s that for flexibility?
