Abstract
An apparatus and a method for indicating a call charge on a display of a facsimile device determines whether a message which is included in a D-channel of service information is a facility message or a display message. If the message is a facility message, the call charge is calculated by multiplying the number of calls included in the facility message by a call rate, and the call charge is outputted to a display window and/or a printer. If the message is a display message, the call charge included in the display message is detected, and the call charge is outputted to the display window and/or the printer. Accordingly, a user can identify the call charge easily and conveniently.
