Why is there no phone call when I receive a WhatsApp call - briefly?
There is no traditional phone call associated with a WhatsApp call because WhatsApp uses Voice over Internet Protocol (VoIP) technology instead of the standard Public Switched Telephone Network (PSTN). This allows calls to be made using an internet connection rather than a cellular network, thereby reducing costs and providing additional features like video calling and group chats.
Why is there no phone call when I receive a WhatsApp call - in detail?
There are several reasons why receiving a WhatsApp call does not trigger a traditional phone call. To understand this, it's important to delve into the technological differences and functionalities of these two communication methods.
Firstly, WhatsApp is a Voice over Internet Protocol (VoIP) service, which means it uses the internet to make calls rather than relying on the traditional telephony network. When you receive a call on WhatsApp, the app handles the transmission of voice data through your device's internet connection, either via Wi-Fi or mobile data. This is fundamentally different from how traditional phone calls work, which use the cellular network to transmit audio signals.
Secondly, WhatsApp operates independently of the cellular network infrastructure used for regular phone calls. When you receive a call on your mobile device, it typically comes through the carrier's network, utilizing specific frequencies and protocols designed for voice communication. WhatsApp, however, bypasses this system entirely, using its own protocols and servers to facilitate the connection between users.
Additionally, WhatsApp offers features that are not available on traditional phone calls, such as end-to-end encryption, which secures the call's data transmission. This added layer of security is unique to VoIP services like WhatsApp and is not a feature of regular phone calls. Furthermore, WhatsApp calls can be made across different platforms (Android, iOS, Windows, etc.), whereas traditional phone calls are typically limited to devices that support cellular networks.
In summary, the absence of a traditional phone call when receiving a WhatsApp call is due to the distinct technologies and functionalities employed by these two communication methods. While both allow for real-time voice interaction, they do so through different means and infrastructure, ensuring that WhatsApp calls remain separate from traditional phone calls.
