VoIP Software Services: The Basics

The way VoIP works is by converting analog audio signals into digital data. This can be from a microphone or phone. This is then transmitted over the internet connection.

The data at the other end is then converted back into an audio signal, so the receiver can hear it through their speakers or phone system.

VoIP is not a new concept

This concept has actually been in existence since around the 1970, but its barrier to widespread adoption was the comparatively low speeds of the internet.

Today, that problem no longer exists, so VoIP software services are practical for use by the masses.

What Are The Advantages Of VoIP Software Services?

VoIP has several advantages over traditional phone lines:

  • Overall Cost: If we think back to phone calls even a few years ago, the tariffs for calling long distance were eye-watering. For example, from the UK to Australia. VoIP calls are miles cheaper than traditional ones, especially for long distance.
  • Device flexibility: With VoIP, you can make or take a call over any device that has an internet connection in theory. You don’t have to be restricted by a handheld phone as traditionally we all were.
  • Range of features: With traditional phone calls, we were limited to the call itself, and possibly a voicemail system. With VoIP systems, you can have lots more features, such as call forwarding, and conference calling.
  • Software integration: The technology in the best VoIP software systems can be integrated across the likes of other email, chat and communication tools to provide more of an all in one service.

VoIP software services today are increasingly impressive.

Since we are ever more reliant on an internet signal, the flexibility, cost and features have seen more and more people adopt the technology – for both individual and business use.

What Is A VoIP Phone?

A VoIP phone (Voice over Internet Protocol phone) is used (as we explained above) to make and receive calls over the internet.

A VoIP phone can be hardware or software based

VoIP phones can be hardware-based. These take the form of a physical phone, complete with a display and keypad.

Alternatively, they can be software-based, like a computer program which enables you to use your microphone and speakers on a computer (or other device) to connect.

How Does VoIP Work?

A simple step-by-step of how VoIP works:

A person speaks into a phone, creating an audio signal generated by a phone, microphone or some other alternate device.

A digital ‘analog-to-digital’ converter (ADC) changes this signal into digital data. After this, the data is split up into small packets, which can then be sent and transmitted over the internet connection.

These packets of digital data reach the receiver via the internet connection.

Then, put simply, they get converted back. After it is once again an audio signal, it is played through speakers so the recipient can hear it.

Here’s that explanation in a diagram:

What do you need for VoIP

To use VoIP software services you’ll need something that can generate the original audio signal, such as a phone, or microphone.

You’ll need an internet connection to transmit the packets of data.

And you’ll need a device at the other end that once the signal is converted back to audio, will play that audio to the listener.

This can be a computer, iPad, phone etc.

How VoIP is used

The tech is fairly simple, but there are a wide range of ways that you can set up VoIP, depending on your individual circumstances. Your requirements might also be different if you’re a business, or individual.

In the modern world, VoIP is typically integrated into a wider program with more functions that also include chat, messaging and email.

It’s just one part of an overall communication package.
