VoIP (Voice over Internet Protocol)

What is VoIP?

VoIP stands for Voice over Internet Protocol — a technology that allows you to make phone calls using an internet connection instead of traditional phone lines. It converts voice into digital signals and transmits them over the internet.

How VoIP Works

When you make a VoIP call:

1. Your voice is converted into digital data
2. That data is transmitted over your internet connection
3. On the receiving end, it’s converted back into audio

VoIP works through apps (like Zoom or WhatsApp), desk phones with VoIP service, or cloud-based platforms connected to IP networks.
