“Welcome to the game. The rules are simple: talk or disconnect.”
🎧 Imagine this:
You pick up your phone, tap a name, and start talking.
No wires. No towers. Just the internet.
That’s VoIP — Voice over Internet Protocol. It’s how your voice travels across the internet instead of through copper lines or mobile towers.
🧠 So… how does it work?
In old-school phone systems (PSTN – Public Switched Telephone Network), your voice is converted into electrical signals and sent over physical lines.
With VoIP, your voice gets:
- Chopped into digital packets
- Sent across the internet
- Reassembled on the other end
Think of it like teleportation — but for sound.
🕹️ Old phones = walkie-talkies with rules
💡 VoIP = voice emails sent in real time
📱 Real-World VoIP: You Already Use It
Here’s where VoIP hides in plain sight:
- Zoom and Google Meet
- WhatsApp or Signal voice calls
- Microsoft Teams
- Discord voice chat
- Smart assistants and intercoms
All powered by VoIP, even if you never noticed.
🔧 What Makes VoIP Work?
To make a VoIP call, you need:
- A device — phone, browser, softphone, etc.
- A network — Wi-Fi or mobile internet
- A protocol — to set up, manage, and end the call
That’s where SIP comes in — the signaling hero we’ll meet soon.
🏁 TL;DR – Did You Survive?
- VoIP = Voice over Internet Protocol
- Sends your voice as data packets over the internet
- Replaces traditional phone lines
- Used by apps you already know and love
- Relies on protocols (like SIP) to work its magic
- We’re just getting started...
