DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of a dialing device according to an embodiment of the present invention, and FIG. 2 shows a re-dial processing flow.

In FIG. 1, reference numeral 101 denotes a station line interface means for acquiring a station line and sending out a selection signal to the station line. Reference numeral 105 denotes tone detection means for detecting voice band signals such as busy tones and ringback tones arriving from the office line. Reference numeral 103 is an operating means having a hook switch, a dial button, and a redial button. 106 is a temporary storage means for dialed information;
Each time a dialing operation is performed, the dial information is once stored in this dial information temporary storage means. Reference numeral 102 denotes a redial information storage means for storing dial data when making a redial call, and when the called party is busy or does not respond, the dial data of the temporary dial information storage means 106 is copied to the corresponding area. . 104 is a central office line interface means 101 and a redial information temporary storage means 10.
2. Control means for controlling the operation means 103, the tone detection means 105, and the dial information temporary storage means 106.

In the dialing apparatus of this embodiment having the above-mentioned components, the process of registering redial information and controlling when a dialing operation is performed will be explained with reference to FIGS. 1 and 2.

When the user of the dial device goes off-hook, the control means 104 detects this via the operating means 103 (step 201). The control means 104 immediately controls the office line interface means 101 to acquire the office line (step 202), and also clears the contents of the dial information temporary storage means 106 (step 203). Next, when a series of dial operations are performed by pressing the dial button of the operation means 103 (step 204), the control means 104 controls the office line interface means 101 to send a series of dial signals to the office line ( Step 2
