What is phone works both ways?

A phone works both ways as it allows communication between two parties, both sending and receiving information or messages. When making a call, the person using the phone can speak and transmit their voice to the other party, who can hear and respond accordingly. Conversely, the other party can also initiate contact by calling the phone user and start a conversation. This two-way functionality is made possible through the use of a microphone and a speaker. Digital signal processing technology also allows the phone to convert audio signals into digital data, which is transmitted over a network and reconverted into sound at the receiving end. This feature has made phone communication a convenient and essential means of communication for personal and business purposes.
