What Is VoIP?

VoIP stands for Voice over Internet Protocol. It is an advanced technology that allows you to place calls using the internet instead of the traditional phone lines. Thanks to the widespread availability of broadband, VoIP is the preferred choice of many businesses and consumers alike.

So, apart from internet connectivity, what is it that makes VoIP distinctive and worth the investment? VoIP comes loaded with powerful features that aren't found in analogue phones. Moreover, it costs less than what it takes to install a phone line. Above all, VoIP is popular because you can use it from any location, as long as you have an internet connection.

How Does VoIP Work?

VoIP thrives on the Internet Protocol, the fundamental building block of the internet. Every user has a unique Internet Protocol address or IP address. All digital devices communicate and connect via an IP address.

When it comes to phone calls through VoIP, the conversation is transformed into small data packets, and they are transmitted between your phone and your VoIP provider. To understand this process in detail, we've broken it into four steps:

  1. Your phone connects to your router in your Local Area Network (LAN).
  2. When you dial a number, your IP address tells your provider to connect with the recipient.
  3. Your VoIP service connects the call and exchanges data packets from your phone.
  4. Your IP phone transforms these digital signals into sounds or voices that you can hear and respond to.

VoIP enables all this without any extensive infrastructure or specialised Private Branch Exchange (PBX). VoIP has a cloud-based PBX packed with features like voice mailing, call routing, and conferencing. You can use Ethernet cables or a strong WI-Fi connection. Either way, your expenses will be much lower than what you will be spending for traditional telephony.

Top Features Of A VoIP Phone System

Investing in a VoIP service gives you unlimited access to many incredible features that simplify and streamline your communication processes. A VoIP system has:


Auto attendants direct your customers to the right agent or team. Customers calling your VoIP service are guided to dial certain numbers that route their call to the department they want. Auto attendants provide immediate and effective customer service without requiring agents to take phone calls.

Call recording

Monitor your team's efficiency and call-handling prowess with VoIP's call recording feature. This feature is blanketed with ample security to ensure authorised access to the recorded calls. This data can also be used to find areas of improvement for your team or agents.

VoIP Security

VoIP services have in-built security to protect the data packets that travel through the internet. You can safeguard your VoIP service with call encryption, Transport Layer Security (TLS), Secure Real-Time Transport Protocol (SRTP) scramble to prevent eavesdropping and call tapping.

Unified Communications (UC)

Unified Communications integrates your company's various communication channels onto a single platform. This feature facilitates easy communication and even allows callers to flip calls between mobile devices. With UC, you can perform key functions like instant messaging, screen sharing, audio and video conferencing, and team chats.

Voice quality

VoIP headsets and phones prove noise-cancelling capabilities. VoIP enables High Definition (HD) voice quality that sounds twice as clear as a standard phone call. VoIP's HD sound quality is possible for even long distance phone calls.

Now that we've explored VoIP's features let's unpack the pros and cons of using VoIP services.
