Internet calling is also referred to as Internet telephony. It refers to making calls over the internet using a technology known as Voice over Internet Protocol (VoIP). The world is increasingly becoming digital. Therefore the leaders in the tech business are continually seeking for ways to make life easier through the internet. As a result, the way people make telephone calls in slowly taking a revolution with the penetration of internet calls. Most social media platforms have provided an option to make the internet calls.
The Internet calling System
The VoIP is broadly used to refer to the system of transmitting the calls through the internet. The system used is similar to what is used in the traditional telephone system. Meaning that, it involves generating signals; channelling the signals; converting the signals from analog to digital and encoding the signals. The digital codes are transmitted through the internet. The voice and video signals are transmitted using IP packets. At the receiver end the digital audio and video codes are converted back to the typical audio and video signals.
When one is making the internet call using the traditional telephone, the Analog Telephone Adapter (ATA) is used. The ATA helps in converting the analogue audio message into digital codes which can be transmitted through the internet. The ATA is also used to convert back the digital codes to analogue audio messages that can be received on the other end. When the call is made on a computer, the voice and video messages go through the same process, only that in this case there is no external ATA.
What is an Internet Calling Account?
Internet calling is gaining popularity due to its benefits over the normal voice calls. Some of its benefits include the ease of making international calls. The other, possibly the biggest advantage, is that they are usually cheaper than the network provided calls. This is because internet calls are usually free and only require one to have an internet connection. On some platforms, one has to have an Internet calling account to make the calls.
To make internet calls using an android phone, one needs to set up an account. The account is referred o as a “Session Initiation Protocol’. This account helps in converting the voice and video message to digital data over the IP networks. A SIP is easy to setup since it does not need one to use other platforms such as Google voice, Skype or such. Such an account can be opened for free using a platform such as the “getonsip.com’. With a SIP account, one can make free VoIP calls from all over the internet.
An internet account depends on the platform one is using to make the internet calls. For example, recently, Facebook has introduced an option to make a call. This is a classic example of an internet call. Therefore, one only needs to have a Facebook account to make a social call.
The Internet Calling Devices
One can make an internet call using a computer. This is because computers have an inbuilt technology to transmit voice and video messages over the internet. Traditional phones can also be used. However, since they do not have any technology to convert audio messages to digital codes, they are connected o an ATA.
Due to technological advancement, digital IP phones have come up. They use protocols such as the Skinny Client Control Protocol (SCCP) or the SIP.
Currently, smartphones, blackberry phones, tablets, and iPhones are being used to make VoIP. This is because they are developed with the technology to perform VoIP. Smartphones are the dominant players in the VoIP industry because of their portability and their effectiveness to use anywhere.

All in all, some platforms have come with up high-quality audio and video making the internet calling experience as smooth as calling through the phone. A good example is the Skype with their recent launch of the Internet Phone Wizard. The internet phone Wizard is an Actiontec hardware that looks similar to the modem. With the wizard, all you need an internet connection and a Skype account.
The device allows one to use a cordless or a corded phone to make calls through Skype. One can make calls to any Skype user or call people with no Skype account but at an added cost. To use it, one is supposed to insert the wizard on the USB port. This device doesn’t need an external power source as it uses the USB power. The device connects the PC to the home line.
With the increase in the popularity of the internet calling services, there is bound to be a shift from traditional telephony to digital telephony. Internet Calling has leverage over traditional calling since it has a lot of benefits. A major challenge facing the traditional method of calling is the regulations placed by the network provider. Some of these regulations create a barrier for international calls. Such a problem has been solved by internet calling as it is easy and convenient to make a call from anywhere to any part of the world.
