Dial‐Back

Used as a control over dial‐up telecommunications lines. The telecommunications link established through dial‐up into the computer from a remote location is interrupted so the computer can dial back to the caller. The link is permitted only if the caller is calling from a valid phone number or telecommunications channel.
