New to VoIP? Here’s how it works!

Jump to: navigation, search·Lundi 23 juillet 2018·Reading time: 3 minutes Copper wires and handsets are a thing of past. The present and future of telecommunication lie with VoIP. Voice over Internet Protocol (VoIP) allows you to make phone calls from anywhere and anytime by using the internet, a headset, and… the Voice over IP.

What is VoIP?

It is a technology which converts voice into digital signal packets and provides you the ability to call directly from a VoIP phone, computer or any other data-driven device. These data packets travel over the internet similar to any other type of data like images, emails, or instant messaging services. Using VoIP, you can make calls to traditional cell phones and landline systems.

How is a VoIP Call placed?

There are many ways to place or to initiate a VoIP call such as the following:

1. Analog Telephone Adapter

Analog Telephone Adapter, also commonly referred to an ATA, is one the most common way used to connect to a VoIP network. With an ATA, a traditional telephone is connected to a device. The ATA helps to convert the analog voice signals generated by your traditional telephone and then converts those analog signals into digital packets. These digital packets are later on transmitted over the internet, similar to an email or any other digital file.

2. IP Phones

Think of IP Phones just like your simple phones, but with the ability and technology to digitize the voice directly into your device. Unlike an ATA, no conversions are required in IP Phones. Here it is performed directly and it either connects directly with the VoIP service through a router or through a Wi-Fi connection. These phones are not specifically your traditional phones but are more like a software-based system which helps to place calls, similar to those found in computers or portable devices.

How is a VoIP Call routed?

VoIP works quite differently as compared to traditional phone routing system. With VoIP, the internet serves as the exchange and picking up the phone only initiates the process of sending data packets to the VoIP server. Once the connection to the VoIP server is made, you will hear a dial tone.

Once the connection is made, the VoIP server tries to locate the other person to whom you are trying to call. If the number is another VoIP number, the server will direct the call over the internet. Whereas, if it is a traditional number, then the server will take the necessary steps to generate an electric circuit, like the one in the traditional phone system, to route the call successfully.

Wrapping Up

Adoption of VoIP services is increasing at a rapid rate. With so many amazing functionalities and features that it has to offer, it has become one of the most widely adopted technology.
