How does VoIP work?
VoIP works by converting your voice into digital data, transmitting it over the internet, and converting it back to sound on the other end. It's a process that happens so quickly, you won’t notice a thing! Here’s a simple breakdown of how it works:
- Voice Capture: Your voice is converted into digital data.
- Packetization: The data is divided into small packets.
- Transmission: These packets travel over the internet.
- Reception: At the other end, the data is reassembled and turned into sound.
- Communication: And just like that, you’re speaking in real-time!
RTP (Real-time Transport Protocol) and SIP (Session Initiation Protocol) are VoIP protocols that ensure smooth call management.
