10.4 Callback Overview
Callback serves two purposes. One is security. When set to callback to a fixed number, an intruder will not
gain access to your network even if he/she stole the password from your user, because the Prestige always
calls back to the pre-configured number.
The other is ease of accounting. For instance, your company pays for the connection charges for
telecommuting employees and you use your Prestige as the dial-in server. When you turn on the callback
option for the dial-in users, all usage is charged to the company instead of the employees, and your
accounting department can avoid the hassles of accountability and reimbursement.
