What happens when you call someone through WhatsApp - briefly?

When you initiate a call through WhatsApp, the application utilizes your device's internet connection to establish a VoIP (Voice over Internet Protocol) call. This allows for real-time voice communication with the recipient, bypassing traditional cellular networks and potentially saving on phone call charges.

What happens when you call someone through WhatsApp - in detail?

When you initiate a call on WhatsApp, several processes occur behind the scenes to ensure seamless communication. The call starts with your device sending a request to WhatsApp's servers to establish a connection with the recipient's device. This initial step involves verifying both parties' phone numbers and ensuring that WhatsApp has permission to use your microphone and camera, if video calling is selected.

Once the connection is established, the call is routed through WhatsApp's servers using end-to-end encryption. This means that only you and the recipient can access the content of the conversation, ensuring privacy and security. The voice or video data is compressed and then transmitted in real time to minimize latency and maintain a high-quality call experience.

During the call, WhatsApp uses advanced algorithms to adapt to network conditions. If you are on a poor internet connection, WhatsApp can automatically switch to a lower quality setting to ensure that the call continues without interruption. Similarly, if the recipient has a weak signal, WhatsApp may adjust the transmission rate accordingly.

WhatsApp also supports additional features during calls. For example, you can mute or unmute your microphone, turn on or off your video camera, and even switch between voice and video calls mid-conversation. These options are available through the call interface and allow users to customize their calling experience based on their preferences and needs.

After the call ends, WhatsApp provides an option to save the call details in your chat history. This feature allows you to review important information discussed during the call or set reminders for follow-up actions. Additionally, WhatsApp may use data from calls to improve its services, but this is done while respecting user privacy and adhering to relevant regulations.

In summary, initiating a WhatsApp call involves establishing a secure connection, routing through encrypted servers, and dynamically adjusting to network conditions. The platform also offers customizable features during the call and provides options for saving call details afterward.
