Abstract
The object of this invention is to provide a facsimile communication supplementary service device that allows facsimile communication users to receive accurate service information from telephone switching facilities without performing any operations whatsoever. When a call is received, the facsimile signal analysis and decision part determines whether said call is a facsimile signal, and if it is, monitors the communication until it is completed. When the communication is completed, the charging system calculates the communication charge and the facsimile response part prepares the facsimile information. Then, if the originating party requested for the automatic immediate charge notification service, then the system calls back the originating terminal and sends said facsimile information. As a result, the originating terminal, if it is a facsimile terminal, can receive information on communication charge as a facsimile message. Consulting information may also be added to said charge information.
