Telephone call

A telephone call, phone call, voice call, or simply a call, is the use of a connection over a telephone network between two parties for audio communication. To start a call, the calling party, the caller, opens a connection for a particular phone number and waits for an answer to the request, often indicated by an audible ringtone. To answer the call, the called party accepts the request to start a conversation. A party is most commonly a single person, but can be a group of people or a machine. In some contexts, the term A-Number refers to the caller and B-Number refers to the called party.
