Abstract
A facsimile apparatus has a plurality of portable units, and enables a subscriber to make a call reservation and conduct a telephone conversation on the reserved call, using the portable units. A base unit of the facsimile apparatus sets up a call reservation in response to a call reservation request signal from the portable unit, while the facsimile apparatus transmits and receives image data. Upon completion of transmitting and receiving the image data, the base unit connects a voice communication path between the portable unit and a facsimile of the other party, so that the subscriber can make the call reservation and talk with the other party over the telephone by using the portable unit.

A method for making a call reservation using a portable unit in a facsimile apparatus, comprising steps of:
- setting up a call reservation using the portable unit, while the facsimile apparatus is operating in a facsimile mode with a facsimile apparatus of a subscriber;
- displaying a call reservation error message on a display unit of said portable unit, when said step of setting up a call reservation is performed while the facsimile apparatus is not operating in said facsimile mode;
- and
- upon completion of said facsimile mode, automatically connecting a voice communication path between said portable unit and said facsimile apparatus of said subscriber for enabling said subscriber to talk with a user of said portable unit, when said call reservation has been set up.

A method for making a call reservation using a portable unit in a first facsimile apparatus, comprising steps of:
- setting up a call reservation into a base unit of the first facsimile apparatus by using a keyboard of the portable unit, while the first facsimile apparatus is operating in a data communication mode with a second facsimile apparatus;
- connecting a voice communication path between said portable unit and said second facsimile apparatus, when said call reservation has been set and upon receiving an acknowledge signal from said second facsimile apparatus, to enable a user of said portable unit to talk to a user of said second facsimile apparatus after completing operation in said data communication mode;
- and
- displaying a call reservation error message on a display unit of said portable unit, when said step of setting up a call reservation is performed while the first facsimile apparatus is not operating in said data communication mode.

A method for making a call reservation using a portable unit in a facsimile apparatus, comprising steps of:
- setting up a call reservation in a base unit of said facsimile apparatus in response to a call reservation request signal from the portable unit, while said facsimile apparatus is in a facsimile mode of operation;
- transmitting protocol signals including a call reservation request signal to a facsimile apparatus of a second party, upon completion of said facsimile mode of operation;
- transmitting a tone generation signal indicating initiation of a voice communication mode of operation to said portable unit, upon receiving an acknowledge signal, in response to the call reservation request signal, from the facsimile of the second party;
- causing the portable unit to transmit a call request signal to said base unit, if a user of said portable unit requests to make a call upon hearing a signal tone generated in response to the tone generation signal;
- printing a call failure message, if the call request signal is not received from the portable unit during a predetermined time period;
- connecting a voice communication path between said portable unit and the facsimile apparatus of said second party, upon receiving said call request signal;
- and
- conducting a voice communication between the user of portable unit and the second party over said voice communication path.
