How Phone Calls Work on WhatsApp: A Detailed Guide
WhatsApp, the popular messaging app, has revolutionized the way we communicate. One of its key features is the ability to make phone calls. In this article, we will delve into how phone calls work on WhatsApp, exploring the technology behind it and the steps involved in making a call.
Understanding the Technology
WhatsApp uses the internet to make phone calls, a process known as Voice over Internet Protocol (VoIP). Unlike traditional phone calls that use the Public Switched Telephone Network (PSTN), VoIP converts your voice into digital data that travels over the internet.
Here’s a simplified breakdown of how VoIP works:
| Step | Description |
|---|---|
| 1 | Your voice is converted into digital data by your device’s microphone. |
| 2 | This digital data is then compressed to reduce the amount of data that needs to be transmitted. |
| 3 | The compressed data is sent over the internet to the recipient’s device. |
| 4 | The recipient’s device decompresses the data and converts it back into audio using its speaker. |
VoIP requires a stable internet connection to work effectively. This is why you might experience call drops or poor call quality if your internet connection is weak.
