Voice over Internet Protocol (VoIP) telephony is a technology that enables voice communication and multimedia sessions over the internet rather than traditional telephone networks. With VoIP, analog voice signals are converted into digital data packets, which are then transmitted over the internet and reconverted into audio at the receiving end. This digital communication method offers an alternative to the traditional Public Switched Telephone Network (PSTN) and has become increasingly popular for its cost-effectiveness, flexibility, and additional features.

Key aspects of VoIP telephony

Digitisation of Voice Signals

VoIP converts analog voice signals into digital data by breaking them into packets. These packets are then transmitted over the internet.

Internet Transmission

Instead of relying on dedicated telephone lines, VoIP uses the existing internet infrastructure for communication. This can result in cost savings, especially for long-distance and international calls.

Cost Efficiency

VoIP services often provide lower-cost alternatives for both domestic and international calling compared to traditional phone services. Many VoIP providers offer flat-rate plans or per-minute billing, contributing to cost savings.

Flexibility and Mobility

VoIP allows users to make calls from anywhere with an internet connection. This flexibility is particularly valuable for remote workers or individuals who need to stay connected while on the go.

Additional Features

VoIP telephony often comes with a range of additional features not commonly found in traditional phone services. These may include video calling, instant messaging, voicemail-to-email, call forwarding, and conference calling.

Integration with Other Systems

VoIP systems can be integrated with other business applications and communication tools, enhancing overall efficiency and collaboration within an organisation.

Scalability

VoIP systems are scalable, making it easy for businesses to adapt their communication infrastructure as they grow or change. Additional lines or features can be added without the need for extensive physical infrastructure changes.
