What are Phone Calls?

Phone calls are a wireless or wired connection made over a telephone or a mobile phone between two people. Two parties are involved in a phone call, the caller and the receiver. A caller dials the number of the one he wants to call, and the recipient hears a bell or a tune to which he picks up the call. The call establishes a connection between them through which they can communicate. The voice is converted into signals and is transmitted through wired or wireless technology.
