A voice call is a communication method that allows two or more people to talk to each other in real-time using audio. This can be done through traditional landline telephones or mobile devices, such as smartphones. Voice calls transmit sound waves, enabling participants to hear each other clearly, regardless of their physical location. Voice calls can be made over various networks, including cellular networks and the internet. With the rise of technology, applications like Skype, WhatsApp, and Zoom also offer voice calling features, allowing users to connect with others using their internet connection.
