Voice over Internet Protocol (VoIP) is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. Think of it as sending your voice over the internet just like you send emails or other data.
When you speak into a microphone (on a computer, smartphone, or VoIP phone), your voice's analog audio signals are converted into digital data packets.
These digital packets are sent over the internet to their destination. They travel the most efficient route available at that moment, optimizing speed.
Once the packets reach the recipient, they are reassembled in the correct order and converted back into audio signals so the person can hear you.
Usually free. Requires a computer with mic/speakers, internet, and software like Skype or Zoom.
Call any landline or mobile from your computer. Typically involves a small service fee.
Apps like WhatsApp and Viber use VoIP technology for calls over Wi-Fi or mobile data.
Use traditional analog phones. An ATA connects your phone to the router for analog-to-digital conversion.
Look like normal phones but connect directly to the internet via Ethernet or Wi-Fi. Native VoIP support.
