If someone is on a phone call and receives a WhatsApp call, will it be busy - briefly?
If you are already engaged in a traditional voice call, receiving a WhatsApp call simultaneously will not make the line busy; both calls can be handled independently.
If someone is on a phone call and receives a WhatsApp call, will it be busy - in detail?
If an individual is engaged in a traditional voice call via their mobile device, receiving a simultaneous WhatsApp call will not result in the WhatsApp call being "busy." This distinction arises from the different technological platforms and protocols employed by each type of communication.
A traditional voice call utilizes the cellular network to establish and maintain a connection between two parties through the Public Switched Telephone Network (PSTN). When an individual is on such a call, their mobile device's radio resources are dedicated to sustaining this connection, effectively making the phone line "busy" for any additional voice calls attempting to use the same network.
In contrast, WhatsApp calls are facilitated through Voice over Internet Protocol (VoIP) technology, leveraging the internet rather than the cellular network. When a WhatsApp call is placed, it does not interfere with or compete for resources on the cellular network. Instead, it operates independently using data connectivity, typically via Wi-Fi or mobile data.
Therefore, while an individual may be engaged in a traditional voice call, their device can still receive and manage WhatsApp calls without any interference or conflict. The "busy" status only applies to simultaneous attempts at establishing additional voice calls over the cellular network, not to internet-based communications like WhatsApp calls. This technological differentiation allows for seamless multitasking between traditional voice calls and VoIP services such as WhatsApp.
