Abstract
The present invention provides a technique that enables an image communication apparatus capable of performing voice communication and T.30 in-band FAX communication over the IP network to positively detect a CNG signal and achieve switching to FAX reception in the answerphone connection mode and the FAX/TEL-switching mode. The communication apparatus includes a MODEM that controls facsimile communication and a SLIC that controls a telephone. A selector includes switches for connecting the IP network and the MODEM, and switches for connecting the IP network and the SLIC. A CPU controls the switches of the selector such that signals from the IP network are supplied to both of the MODEM and the SLIC.
Claims12
A communication apparatus that executes communication via an IP network, comprising:
- a facsimile controller configured to control facsimile communication;
- a telephone controller configured to control a telephone;
- a first connection unit configured to connect the IP network and said facsimile controller;
- a second connection unit configured to connect the IP network and said telephone controller;
- and
- a connection control unit configured to control said first connection unit and said second connection unit such that signals from the IP network are supplied to both of said facsimile controller and said telephone controller.
A method of controlling a communication apparatus that executes communication via an IP network, including a facsimile controller for controlling facsimile communication, a telephone controller for controlling a telephone, a first connection unit for connecting the IP network and the facsimile controller, and a second connection unit for connecting the IP network and the telephone controller, comprising:
- controlling the first connection unit and the second connection unit such that signals from the IP network are supplied to both of the facsimile controller and the telephone controller.
A non-transitory computer-readable storage medium storing a computer-executable control program for causing a computer to execute a method of controlling a communication apparatus that executes communication via an IP network, including a facsimile controller for controlling facsimile communication, a telephone controller for controlling a telephone, a first connection unit for connecting the IP network and the facsimile controller, and a second connection unit for connecting the IP network and the telephone controller,
- wherein the method comprises:
- controlling the first connection unit and the second connection unit such that signals from the IP network are supplied to both of the facsimile controller and the telephone controller.
