🎭 What Even Is VoIP?

“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

🔧 What Makes VoIP Work?

To make a VoIP call, you need:

1. A device — phone, browser, softphone, etc.
2. A network — Wi-Fi or mobile internet
3. A protocol — to set up, manage, and end the call

That’s where SIP comes in — the signaling hero we’ll meet soon.
