The main control unit 15 of the main unit 1 places the telephone line 11A on hold in the main unit 1 in response to the incoming call interruption from the network 4 detected by the information receiving unit 17 (detection means). Because of this, out of the slave units 2A to 2M, a call is made to the slave unit that can respond to the incoming call to the telephone line 11A.
Perform Step 3. In this call 43, it is displayed that the incoming call is an interrupted call during a call as a general incoming call. Furthermore, information indicating the telephone line (telephone line 11A) where the call interruption interrupt occurred or information indicating the child device (child device A) holding the telephone line may be displayed.

When a slave unit other than the slave unit A, for example, the slave unit B responds to the call 43 from the time T ₂ (time T ₃ ), the main control unit 15 controls the exchange processing unit 14 to control the telephone line. Release the hold of 11A and release the telephone line 1
A hooking signal (switching signal) is sent to 1A, and the telephone line 11A and the slave unit B are connected (communication forming means). In the network 4, in response to a hooking signal from the telephone line 11A, the destination X is put on hold in the network 4, and the destination Y is switched and connected to the telephone line 11A. As a result, an outside line call (interruption call) 44 between the partner Y and the slave unit B is formed.

In accordance with the formation of the outside line call 44, the main control
The unit 15 starts the call interruption processing of FIG. First,
Start the call loop processing by steps 100 and 110
You. In this call loop processing, the destination X is held first.
In this case, the child device A is held at the time T _FourTelephone line 1
When a response (release of hold) operation to 1A is performed (step
Step 100: YES), the main control unit 15

As described above, in response to the incoming call interruption of the telephone line 11A being held, the slave unit A holding the telephone line
The other handset B responds and forms an interrupt call, and in response to a re-answer operation at handset A during this interrupt call,
Since a call is made to the slave unit B during a call, the slave unit A
Automatically responds to a request to resume a call to a sub-unit of an interrupted call in response to a simple operation of re-responding to a held telephone line by a user and responding to a series of operations from hold to re-response by the user of sub-unit A The call is interrupted during the call, so that the user does not feel much burden on the operation, so that the call interruption interrupt service can be used smoothly.

As a call during the call from the slave A to the slave B, a call interruption 45 by the voice of the user of the slave A is formed, so that the user of the slave A can send the call to the slave of the interrupt call. It is possible to accurately notify the user of the slave unit B by voice that the call is to be resumed. Note that the call during the call from the slave A to the slave B includes the slave B and the destination Y.
A three-party call may be formed in which the slave A directly interrupts the external line call 44 with the telephone, or a voice call for outputting a sound from the speaker of the slave B instead of the three-party call may be formed. Further, the present invention is not limited to the call interruption by voice, and a ringing tone or information display for requesting the restart of the call may be output to the slave unit B.

Further, after the call during the call from the slave unit A to the slave unit B is started, the other party of the original call held on the network side in response to the operation of terminating the outside line call by the slave unit B during the call. Since the external line call between X and the slave A is automatically formed, the user of the slave A can resume the call without performing a complicated operation.

In the above-described call loop processing, a handset that performs outside line communication 44 with the destination X is used.
When the call termination operation is performed, as shown in FIG. 5, a hold alarm may be output to the slave unit A, which has previously held the telephone line 11A. In this case, the time T
_In response to the end operation of the slave unit B in step ₆ (step 11
0: YES), the main controller 15 sends a hooking signal to the telephone line 11A (step 111),
The exchange processing unit 14 is controlled to hold the telephone line 11A (step 112). Then, the hold alarm 47 is output to the slave unit A (step 113).

In the network 4, in response to the hooking signal, the destination X which has been on hold is switched and connected to the telephone line 11A. As a result, the other party X is put on hold in the main device 1, and if a re-answer operation is performed on the slave A at time T ₇ in response to the hold alarm 47, the external call 4 between the slave A and the other party X is performed.
8 is reformed. In this way, the end of the interrupted call is automatically notified to the child device of the original call, and the user can smoothly use the interrupted call receiving service during the call without much burden on the operation.
