Gone were the days when children used to play two empty cans wired together using a log string – speaking through one can on one side while the kid on the opposite end places the can over his ears and waits for the message he is about to receive.
From telephone magnetos to wireless phone models, technology has leveled-up so much that the delivery of voice messages and multimedia sessions is now possible over the IP networks.
Now, what really is VoIP? Voice over internet protocol is a grace sent from above where we now can provision communication services such as voice, fax, SMS and voice/messaging through the public internet and not solely via the PTSN or the Public switched telephone network.
So how does it work? The principles utilized by the traditional digital telephones are not far different. This also involves signaling, difitization of the analog voice signals, channel setup, and encoding. But what differs is instead of being transmitted over a circuit-switched network, the transmission occurs as IP packets over a packet-switched network, respectively. Using special media delivery protocols, they transport media streams by encoding audio and video with audio codecs and video codecs.
From scratch, early providers of voice-over-IP services offered technical solutions that quite resemble the design of telephone networks. Do you fancy Skype because you can not just talk but literally see your loved ones from afar? It belongs to the second-generation providers in which they built closed networks for private users bases. While Skype offers the benefit of free calls and convenience talking to your beloveds anywhere and anytime, they charge access to other communication networks, such as the PSTN. Third generation providers gave birth to Google Talk which adopts now the concept of federated VoIP thus, paving its way distant from the architecture of legacy networks.
Amazing isn’t it? Technology never gets boring and continuously awes us while helping our lives become easy in so many levels.
In this era where technology seems to be the answer to almost every problem, we cannot deny that the advancement of technology enabled by the internet have provided a selection of ways for companies to do their businesses along with their employees.
From the uprising recognition of VoIP companies, what really is its difference compared to the good old landline companies?
First, let us describe the classic telephone companies. When people say “landline”, they often refer to a telephone that utilizes a solid core, a twisted pair of copper wire, and plugs into a pin wall jack. Generally speaking, it hasn’t changed much since the year of its invention. Landline phones are based on an analog technology that transmits signals through a series of exchanges in the form of physical switchboxes which connects calls between two phones.
The downside of telephone companies is that the analog connection limits the types of new features that service providers can introduce. Most carriers only offer basic features like call waiting, caller ID, voicemail, and call blocking.
On the other side of the fence comes VoIP. The companies in this business communication technology allows making and receiving calls over the internet. Thus, they do not use twisted pair of copper wires but rather the phone is connected using the same broadband internet connection that plugs into a computer or router. VoIP companies convert calls into digital signals within the phone itself and doesn’t rely on the physical exchanges that landlines do.
Because almost everyone you meet in the street has internet connection, VoIP companies are able to offer a variety and more useful set of features that enable businesses and their respective employees to be more efficient and productive with their everyday communication needs.
Probably when deciding which company are you going to set foot on to for your business needs, four factors need to be considered: features, technology, reliability, and of course cost. By looking deeply unto these four factors, you get to decide which company outsmarts the other or perhaps provides a more useful approach depending on your personal technological needs.
In this day and age where life is fast paced and convenience is a necessity, businesses rely more on VOIP. The latter stands for Voice Over Internet Protocol. The revolutionary technology converts voice information into digital data which can be channeled using the internet, then, changes back to analog signals before reaching the receiver at the other end. It simply means, voice that travels utilizing the same set of rules on the internet.
Long, long, long time ago, there was POTS or Plain Old Telephone Service. Calls, local or long distance, had to travel over circuit switches called Public Switched Telephone Network (PSTN). The system was used worldwide, easy, and needed only a telephone and copper line into any building. A disadvantage was if a line is down, a call can’t get through.
Since VOIP is rooted in the IP world, multiple routes can be set and any available route can be utilized. So if one of the lines is down, the packet can turn to another available and working route to keep the call up. As they say, VOIP works well over all kinds of networks. Also, it is highly portable. Phones calls can be made with any IP enabled device, a computer or even a PDA or Personal digital assistant. Moreover, the technology requires less maintenance, thus, is cost efficient.
Interestingly, how does one use VOIP in placing or receiving calls. There are varied ways. One of which is the use of an ATA or Analog Telephone Adaptor, the simplest and most common way. The device converts the analog signal from the traditional phone into digital data for transfer over the world wide web. ATA often comes with the service. IP Phones or specialized phones with RJ-45 Ethernet connector are also recommended for VOIP calls. The easiest way is computer to computer. Free or very low cost software are being offered by several companies. Simply put together the basics, that is, hardware, microphone, speakers, sound card, the software and internet connection, preferably, a fast one; and VOIP is now possible. Computer to computer incurs no charges, even for long distance calls.
In the US, VOIP is an emerging technology which is utilized by businesses engaged in communications. There are a number of popular providers of such technology from which businesses can select an affordable plan for their needs. VOIP is not only for business but for personal use as well. Connection with family members abroad are now made easy and more so, affordable.

Clever and revolutionary—no wonder VOIP technology is expected to entirely replace the traditional phone system in the near future. VOIP, which stands for Voice Over Internet Protocol works by delivering voice communications through the help of the internet. This technology allows free phone calls and saves you charges from long-distance phone calls contrary to the traditional Public Telephone Switched Network’s circuit-switched telephoney.
Majority of businesses had been switching to VOIP from PTSN because it is way cheaper. The ability of VOIP to run in a single network is significant in lowering of the infrastracture cost. Also, VOIP technology is designed to have a simple user interface which allows users to use it in a convenient way.
There are three known VOIP services being used today. The first is the ATA (Analog Telephone Adaptor) which is the simplest and the most common service that allows you to connect your standard phone to your computer. The second one is the IP phones which becomes a wifi phone when connected to the router provided with all the necessary hardware and software to be able to make an IP call. This allow callers to make VOIP calls in any Wi-Fi hotspot. The third and is said to be the easiest one is the computer-to-computer, the best alternative in making long-distance calls and saves your money.
You will need a microphone, speaker, an Internet connection and you’re good. This service is also possible with PC-to-phone, phone-to-phone, and Internet phone to-PC. Viber and Skype are just two of the most popular VOIP apps used widely. These applications allow you to communicate with your loved ones wherever they are in the world through text messaging, voice calls and video chats over data and Wi-fi. Whether your phone is android, iOS, Windows or Blackberry, it is possible.
