The Different Stages That Lead to VoIP Service

admin — Mon, 29 Mar 2010 01:46:44 +0000

VoIP service is an ideal means of sending telephone calls over IP networks. The Voice over IP works on the principle of converting analog signals to small packets of digital data and then sending them over a broadband internet connection that ultimately connects the users with the service providers. There are several advantages of using this service. The main reason why people acquire this connection is quite straightforward; the expenses incurred while making long distance calls using such a service is low as compared to the traditional phone line connections.

As VoIP service is based on the transfer of digital data, so the service provider can actually do a lot with this technology. Among the most prominent of the services that a service provider can provide are storing of incoming voice mails in the mailbox, sending of email attachments and 3 way calling. Let us consider a scenario in which the user is busy and wants not to be disturbed by any telephone calls. In such situations, the incoming calls can be stored in the voice mail of the subscribers. A person can also send a voice mail as an email attachment which can be accessed on a computer. Then there are plans where up to three people can involve themselves in conference calling. In fact, calling through Voice over IP is far from restricted. The service allows the user to talk to the entire family in one call. Then there are also the options of sending images, videos and voice to people with whom a person is conferencing.

The internet does not differentiate between calls made to a person living next door from calls to people living in another part of the world. The call charges remain the same; such is the benevolence of the VoIP phone service. It is the benefit in price rates that makes people opt for this service in the first place. Moreover the technology is simple and one only requires some simple tools to access the service. An Analog Telephone Adapter (ATA) is provided by the VoIP service provider. This tool helps to convert analog voice to digital samples by use of Analog to Digital Converter. These digital samples are then compressed by the digital signal processors (DSPs). The DSPs make use of codecs for compression and eventually segment ‘voice signals’ to frames that are then stored as ‘voice packets’. The final process involves transfer of these packets in compliance with Voice Communication Protocol or Session Initiation Protocol (SIP).

When these packets arrive at their destination, they have to be decoded; the entire process is carrier out, albeit in a reverse order. The IP packets are decapsulated in compressed data forms. These data are then decompressed to retrieve the original data making use of the same codec that was initially used to perform the compression. The data is then sent through a digital to analog converter that converts it to the original analog voice format for the listener to hear the voice distinctly. So, VoIP service is actually based on a very simple format but requires fast internet service to ensure an effective and soothing calling experience. This becomes all the more important in the context of business VoIP service, wherein the quality of calls becomes a yardstick in determining the expertise of a particular organization.

How Does VoIP Work With Your Current Phone?

admin — Sun, 21 Mar 2010 01:53:18 +0000

Technology is growing and changing everyday. Consider phone service; at one time when people made telephone calls they did so with their phone attached to a jack in the wall and literally “dialed” the number they were calling. Then came the push-button phones; it was great to quickly “dial” the number by pressing the key pad. Soon the cordless phone jumped on the technological scene. This was wonderful; now people could walk around their house and talk without being limited to the phone cord attached to the wall, or worse tripping over the one hundred foot phone cord that they used to walk all around the house and talk on the phone.

Just as people were getting used to the cordless phone, soon came the invention of the mobile phone. It was cumbersome at first but what a thought – being able to use a phone in your vehicle. Now the cell phone is sleek, compact, and can do much more than simply make a call. Enter Voice over Internet Protocol (VoIP) – Internet phone service, how does VoIP work with your current phone?

With this technology, instead of the signals going out over a public network the voice signals travel over your high-speed broadband connection. You do not need to buy a new phone for this service, and you can enjoy substantial savings as you combine both the Internet and phone service into one low monthly rate. The amazing concept of VoIP is that it combines one technology to operate two different types of service; your phone and Internet. Making a call with VoIP technology can occur one of three ways:

* Analog Telephone Adapter (ATA) – With the use of this device, you simply plug in your current phone into the adapter and then connect the adapter to your broadband service (possibly a modem). That is it you can now make calls. The way this system works is by taking the analog signal and changing it into a digital signal sent out over the Internet.

* IP Phones – these types of phones look exactly like analog phones the difference being they have an Ethernet connector instead of the standard phone connector and come equipped with the software and hardware needed for VoIP service built into them. You connect directly to your modem and begin enjoying exceptional quality with your next phone call.

* Computer-to-Computer – All you need for this service is high-speed Internet connections, sound card, microphone, and speakers. Typically, you pay a monthly rate from your Internet service provider.

VoIP – 3 Ways to Make The Call

admin — Sat, 13 Mar 2010 17:39:42 +0000

We’re hearing a lot about Voice Over Internet Protocol (VoIP) these days. I for one am a big fan of this technology. Did you know that you could actually use VoIP in 3 different ways? That’s right! There are really 3 different ways that you can ‘make the call’. Ok, you can actually receive the call 3 different ways as well.

First up is probably the most popular. I use this way myself and most of the residential providers out there today use this as well. What is it?

ATA – Analog Telephone Adapter

Your normal phone plugs into an ATA that you received from your VoIP provider. This is the most common way to get hooked into VoIP. This device takes care of all the magic that occurs when you make and receive your calls over your broadband connection. Your analog phone signal must be converted to digital to be routed through your broadband connection and this ATA does the job.

IP Phone – Internet Protocol Phones

As the name would imply, these are ‘special’ phones. You wouldn’t know it by looking at them. They look like normal phones. What is different about these phones is the electronics inside them and the fact they don’t take a ‘regular’ phone cable (RJ-11). Instead these phones take an Ethernet cable connection (RJ-45) and also come equipped with the necessary electronics to plug directly into your router.

Computer-to-Computer

This is the oldest and possibly the easiest way to get plugged into VoIP. Here instead of using your normal phone or IP phone to make calls through your broadband connection, you use your computer itself! (You could do this over dial-up, but broadband is certainly better) There are a number of services available that offer no cost or low cost service. You’ll need the software and a microphone to speak into and speakers to hear from and of course your computer and a high-speed internet connection. Some providers offer this service for free when their software is being used on both ends of the call.

Watch out for Wi-Fi (using IP phones) and other advancements in VoIP technology. We truly are on the verge of a major breakthrough in telecommunications. So, what are you waiting for? Make the call!

An Overview of How VoIP Works

admin — Fri, 05 Mar 2010 16:33:34 +0000

Voice over Internet Protocol is the newest way in which people are making phone calls today. Though the technology for VoIP has only been available for a relatively short time, it is already gaining worldwide popularity. VoIP is the use of a broadband internet connection for the purpose of making telephone calls. This has many benefits, most notably not having to put up with the outrageous taxes and fees that come with getting telephone service through a company.

There are three main methods in which to set up your VoIP, all of which even a layman can do. First, and most popular, is the simple computer-to-computer VoIP. Users merely download or purchase a “soft” phone (a computer program that acts as a phone) from the Internet that can be used to call any other computer with a similar program. In addition to the soft phone, a person needs speakers, a sound card and a microphone to complete a call.

The second option for VoIP is to purchase an analog telephone adapter. The adapter, once hooked up to both your Internet connection and your phone, can convert normal phone signals into signals that can be sent over the Internet. This has proven to be the simplest and cheapest method of setting up a VoIP. Popular companies such as Vonage are starting to bundle analog telephone adapters with low priced service agreements. The third method of setting up a VoIP is the use of an IP phone. Instead of regular connector cables, IP phones have Ethernet cards that are designed to be hooked into broadband Internet connections.

There are many issues that surround a VoIP including privacy, security and reverse phone lookups [http://www.instantphonelookups.com]. Though VoIP is a big money saver, it is always wise to research all of the facts before abandoning your traditional phone service.

All About VoIP

admin — Sat, 20 Feb 2010 21:55:24 +0000

Voice over Internet Protocol or the VoIP, is basically the process of sending voice through internet protocol, making it convenient for a consumer to make phone calls at cheaper price. VoIP is used not only when using the internet protocol to send or receive calls, but it is also useful when you want to avail the service of traditional phone lines that guarantee better quality & allow bigger space for calls.

When the quality of audio and frequency in VoIP is high, it is very hard for customers to notice the difference between it and a normal telephone. Even the person who is receiving the calls from a VoIP will not be able to guess that the calls are made from a VoIP Network. Transferring PSTN (Public Switched Telephone Network) to VoIP/SIP Session Initiation Protocol) allows VoIP users to send and receive phone calls as done in ordinary phone lines.

Now, enough about VoIP from the scientific point of view. Let us now proceed to the benefits of using VoIP compared to using conventional phone lines. Basically, consumers care mostly about the rates so they would like to know how much can be saved when you purchase a VoIP service. This is one of the advantages of VoIP. It became popular because of its cheap call rates as compared to any conventional phones. It gives you the ability to make unlimited phone calls, long distance calls and low international calls charges with low monthly subscription rate. This is value added service for any consumer.

VoIP can be used in different ways. One possible way is through ATA or Analog Telephone Adapter. ATA is connected between a telephone jack that is already existent and an IP network in order to provide VoIP service. This type of service is generally offered by broadband internet providers such as cable companies and telephone companies.

Simply check the company that provides you with internet cable service or the company that provides your home phone service to see if they offer this service. If you want an easier way, just check the internet out for low rates companies. There are a lot of new companies that are just providing this service and they are concerned about giving the best service with lower rates.

Finally, a VoIP is a better & more economical way of making long distance as well as short distance calls by simply using an internet connection. You can use it for local, nationwide and international calls. You can even make calls to residential phones or cell phones.

How Does VoIP Service Work?

admin — Wed, 10 Feb 2010 16:28:03 +0000

VOIP technology is a one way of sending a voice signal also known as an analog signal in a medium which is digital, i.e, the internet. In practice, the process works like this when you have a standard analog telephone attached to your high speed internet connection with VOIP service. There will be an analog telephone adapter or ATA between the phone and the computer.

In order to place what would normally be a long distance call to a person who doesn’t have VOIP service you key in the number you want. The analog telephone adapter converts the touch tones into a digital format. The digital phone number is sent by the analog telephone adapter to the VOIP routing system at the service provider’s location. The VOIP service provider is located on the internet as well.

The VOIP service provider’s routing system identifies the recipient’s location and sends the call to the Public Switched Telephone Network (PTSN) at that location. The phone rings at the other end and the conversation can begin. Each time you speak, the analog to digital converter in the analog telephone adapter changes the voice tones into packets of digital information that can be transmitted across the internet. When the VOIP service meshes with the Public Switched Telephone Network at the recipient’s end, the digital packets which are the voice tones from you get turned back into an analog signal so that you recipient of your call can understand what you are saying.

The reverse process, i.e. the transmission of what the other person says to you is a mirror image of the first process. Their voice is transformed from analog to digital when it gets to the PSTN/internet connection. The digital packets are sent to the analog telephone adapter at your location where they are converted back into an audible or analog signal to be able to perceive the voice as that of your caller.

The technology to do the conversion from analog to digital and back again has been around as long as digital electronics. For example, your PC sound card converts digital CD information to analog signal needed by the speakers on your computer. The difficult part of the VOIP technology is the necessity to smoothly transmit the digital data over the internet and reassemble it in a continuous stream. This is know as the protocol.

When listening to voice transmission, there can be no gaps in the stream of digital packets or the voices will not be understandable. This part of the technology has only recently been available, but is actually equal or better in quality than you get with standard telephone networks.

The equipment available today that uses VOIP technology can be an analog telephone adapter for your head set through the computer. There are a few VOIP phones that act like a regular analog telephone but have the ATA incorporated into the phone. It’s actually a small dedicated personal computer in your telephone. These VOIP phones can be plugged into the computer with high speed internet connection or into the router.

Lavish Computer VoIP Phone Calls

Though the technology has been around for a lots of years, as the traditional phone companies now it is advances in popularity to prolonged to increase their prices. In the process of VoIP an usual analog audio signals, such as the voices that talked or listened on the phone, has been converted into digital data that can be sent to the computer by using an Internet connection.

Besides all, VoIP is a skilled “reinvention of the phone”. In the three various ways you can put a call by using this technology. Analog Telephone Adaptor is the most abundant and easiest method to practice VoIP technology. This can be immediately assigned through the computer internet to usual telephone. An ATA will received an analog signal and convert it into a digital signal then transfers it to an Internet in small mail boat. Once this small packages reached an other end, the packages were uncovered and transfered back into worth reading data or in an oral expression.

The computer and peculiar software get relief by simply plugged an ATA to your phone. VoIP phone is an other method to unite with VoIP technology, it has a look as an usual phone. The only dissimilarity is the RJ-11 connector is substituted by a RJ-45 Ethernet connector. In VoIP phone the hardware and software previously programmed, so the phone calls get controlled to your router.

Computer to computer is the easiest and ultimate method to unite the VoIP technology. This is where the free long distance phone calls come into play. On Internet various companies provide their software for free download. In this procedure, there should be no other fees overwhelmed except an Internet connection fees.

A power source is a few unfavorable conditions of VoIP. The phone is fully depend upon a power, not similar with an usual phone. At present there is no such method has been introduced to joined other systems such as home alarm system, for these kind of product you would have to keep up an usual phone connection. The other unfavorable conditions of VoIP technology is we cannot dial 9-1-1.

VoIP technology not identify the machine address for communication, so that it is difficult to identified the computer physical address on IP addresses because IP addresses of any computer machine cannot give the physical location of that particular machine which is difficult to identify in an emergency cases.

Common Questions About VoIP

admin — Mon, 08 Feb 2010 03:41:25 +0000

Unless you live in a bubble, you have probably been hearing alot of buzz lately about something called Voice Over IP (VoIP). Perhaps you have heard that you can use VoIP to get cheap or free long distance calling, even Internationally. The good news is that this is true!

VoIP, which stands for Voice Over Internet Protocol is an exciting synergy between computers and telephony, but don’t let that scare you. VoIP is just as easy to use as any ordinary telephone. So, you have heard the buzz and perhaps you are curious about taking the plunge and getting set up with VoIP service. Being so new, VoIP is still somewhat shrouded in mystery. Help is here! In this article we will answer several common questions most people have about VoIP Service and help clear up the confusion about the technology and how it can work for you.

What Exactly is VoIP (Voice Over Internet Protocol)?
VoIP is a new technology that makes use of your broadband connection to route your telephone calls over the internet, rather than using the traditional analog telephone lines. This has proven to be a very efficient and cost effective way to place phone calls to anywhere in the world.

Who Can I call?
This depends upon your service provider. There are a few different flavors of Voice Over IP Service. Most of the larger VoIP service providers you see advertised to the consumer market (such as Vonage, BlueSky, etc..) work just like your existing phone and enable you to call any phone, anywhere.

What’s It Going To Cost?
The cost for this service varies depending on the provider and the service plan you select. Currently, most service providers have plans that cost in the $10 – $25 monthly, which is considerably cheaper than ordinary phone service. Keep in mind that this service includes long distance calls. Usually, you can choose from several plans that vary in cost depending on the level of usage you desire. Most companies also offer an unlimited plan that includes unlimited long distance calls.

You will also be plesantly surprised to find that many services such as caller id, call forwarding, call waiting, three way calling, and even voice mail features often come standard with most VoIP plans. Another great benefit is that as it currently stands (in January 2006), the Government does not apply a tax to your VoIP service, unlike the additional taxes and fees that are applied to your standard phone bill. This can amount to a substantial savings alone, but this may only be a temporary benefit. As VoIP gains in popularity, it is more than likely that the Government will find a way to tax that as well.

Do I Need “Special Stuff”?

This depends on the provider, once again. One thing that you must have is an always on broadband internet connection. This means DSL or Cable Internet, for home users. Depending on whom you get service with, you will likely have to connect just regular phone to an adapter, or maybe purchase a special phone to use with the service. Check for specials before you sign up, sometimes the equipment is given away for free to encourage you to sign up. Regardless, the investment in hardware for home users of VoIP is very minimal, if it costs you at all.

Can I call 911?

You need to check with the provider to ensure that they do indeed provide this functionality. That said, in May 2005, the US Government ordered all interconnected VoIP Providers to provide 911 functionality to their subscribers.

Sounds… Too Good, What’s the Catch?

Well, there is a minor catch which is that if your internet goes out, so does your phone. This isn’t usually too big of a problem, however as most modern broadband ISPs do a great job of maintaining reliable service.

Where Do I Find VoIP Providers?

Usually, it is not important that you find a local provider just as long as the provider you choose is based in the same country. Therefore, the internet is a very valuable resource for finding and comparing VoIP providers.

Which one Do I choose?

The VoIP provider that you choose is a personal choice, as they all tend to work slightly differently. What sounds the most feasible for your setup and usage requirements is the best choice for you. Do keep in mind that this is a rapidly maturing technology and that changes are occurring all the time. You will want to choose a company that you feel will be able to provide you reliable service in the future.

VoIP Tutorial – Understanding How VoIP Can Work For You

admin — Sun, 10 Jan 2010 13:47:41 +0000

VoIP, Voice over Internet Protocol is the future for phone service. While virtual an unknown technology a few years ago, VoIP is becoming common place. With new technology appearing here is a VoIP tutorial on the different types of VoIP.

There are several different setups for VoIP. The basic setup is a free service, normally. It is computer to computer. This is where you use your computer to call another computer and you talk with a headset and microphone connected. Think Skype, MSN and Yahoo.

These services have been around for years, but have improved greatly in their technology of computer to computer VoIP. As long as the person you wish to speak to has the same software and a high speed internet connection, you can speak with them. Next door or around the globe the call can go from your computer to someone else’s.

IP Phones are the next step. These phones have the ability to plug into the router that you use. They look like a traditional phone. They have software built in and are able to use the technology of VoIP to send and receive phone calls. Another up and comer in this category are WiFi phones. They use the technology of wireless to provide phone service. There is usually an installation fee and a monthly service charge.

ATA is the standard. ATA stands for analog telephone adaptor. When you sign up for this service you are sent a special router. This router enables you to plug in a traditional phone. The router is able to route your phone calls using the internet service you have.

There is usually a setup fee and a monthly service fee. You get many of the same service you get on traditional phones, such as caller ID and call waiting. Plans often include unlimited calls and cheaper international rates.

Whichever method you choose, ensure you read the fine print. Many of the subscription service have a contract of one or two years. If you find that it is not the service for you, you will have to pay a disconnection fee.

VoIP is the technology for the home phones of the future. Many traditional companies are starting to use high speed internet to route their calls, as it is more efficient and less costly than phone lines. Finding a provider and plan will become more competitive and technology improves.

Learning the Basics of VoIP

admin — Sun, 10 Jan 2010 02:21:24 +0000

If you have been paying large long distance phone bills, it’s time to introduce you to the VOIP basics. Voice over Internet Protocol (VOIP or VoIP) is the latest telecommunications internet technology. It will allow you to make long distance calls over your internet connection, bypassing most, or all of you your long distance provider’s charges.

However, several large telecommunications companies have caught on to the growing trend for consumers to bypass their charges, and have reacted by offering packaged services that include your regular, local phone line service and the VOIP service that will let you place calls over the internet.

When discussing VOIP basics, it’s important to realize that there are actually 3 types of VOIP technologies that are currently in use. The first is called ATA or Analog Telephone Adapter technology. The ATA technologydoes exactly what it sounds like; it takes the analog signal on your regular telephone line and translates it into a digital signal. T

hat digital signal is then sent via the internet. This is the type of service that the large telecommunications providers are offering. They will mail you the ATA and you can set it up easily on your own.

Another of the technologies that is necessary for understanding VOIP basics still has to do with the phone itself. Instead of using an adaptor to change a regular phone into a VOIP compatible one, you purchase a phone that is designed for making VOIP calls. But that phone won’t plug into a regular phone jack (RJ-11). It will have to be plugged into an Ethernet connection (an RJ-45 jack or a spot on your router).

The necessary hardware and software to make a VOIP call is included in the phone itself.

The third technology involved in learning VOIP Basics is the most exciting for the average consumer, as it doesn’t require a monthly service charge from a provider in order to make free business long distance calls. It is computer-to-computer VOIP service. In this case, you download free or purchase low-cost software that turns your computer into the phone.

In addition to the software, you’ll need speakers so you can hear the other party, a microphone so you can speak to them, a sound card in your computer, and a preferably high-speed internet connection so the signal can travel fast enough to avoid delays in what you or the other party hears.

The person you call doesn’t need to be talking to you over a computer; a regular phone will work just fine. You can use the service on your end to make calls to anyone, anywhere without a charge.

Now that we’ve looked at the VOIP or also know as voice over internet protocol, you might be interested in trying it for yourself. But what you don’t realize is that you most likely already are.

Telephone companies have been using the technology for several years in order to route the mass number of calls they receive more efficiently over their networks.

But to try VOIP at home, download software at sites such as skype site. If you already have the needed items mentioned above (speakers, microphone, sound card and high-speed internet connection), you can be making calls in as little as 5 minutes.
