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?
March 21st, 2010
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
March 13th, 2010
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!
