Busy Tone

The busy tone in telecom is a signal used to indicate that the phone number being dialed is currently unavailable due to the recipient being on another call or the line being busy. In the UK market, the busy tone is a common feature that helps manage call traffic and inform callers of the status of the phone line they are trying to reach. When hearing a busy tone, callers are advised to wait and redial the number at a later time to connect successfully.
