It is possible to make an outside line multi-party call between B and an outside line telephone.

An extension call is established by a particular handset calling another handset. A call to a handset may be made by providing a corresponding extension key for each handset and operating the corresponding extension key, or by assigning a dial key to each handset after operating the extension key. This may be done by inputting the so-called extension number that is provided.

An outside line call is set up by inputting the phone number and month from a specific handset and calling the called station. An external multi-party call can occur, for example, when a handset making an external call calls another handset, or when another handset calls an internal phone to the handset making an outside call. This is set when an interrupt request is made.

FIG. 2 is a flowchart 1 explaining the operation of the telephone 1.
It is. Here, when handset A is in an outside line call state,
Assume a case where slave unit B calls slave @A.

In step a1, it is determined whether the extension key 23 on the handset B has been pressed. When the extension key 23 is pressed, the control circuit 26 determines in step a2 that the call request is for the handset A, and turns on the transmitting/receiving circuit 24 and the antenna 25 in order to request the handset A to receive the call via the parent@10. A call request message is sent via the host.

When base unit 10 receives a call request (No. 8) from handset B in step a3, it is determined in step a4 whether or not it is possible to receive an extension call based on the call status of handset A, and if the determination is negative, If so, the operation ends, and if the determination is affirmative, the process proceeds to step a5. In step a5, it is determined whether the incoming extension call to handset A is an extension interrupt request. If it is not an extension call interrupt request. performs a normal extension connection operation, and if it is an interrupt request, proceeds to step a6.

In step a6, ff1PJ, 10 notifies handset B that the extension is now in a ringing state. Step εL
When the handset B recognizes in step 7 that an extension call is being called based on the information sent from the base unit 10, in step a8 it displays on the display unit 28 that the handset B is currently calling the child+fi A; In step a9, a predetermined ringing tone is generated and output from the speaker 22.

In step alo, the base unit 10 sends an extension to the slave unit A (
child 1 in step a1.1.
When fiA receives the extension call request signal from the base unit 10, in step 2+12, the display unit 18 for the slave unit displays that there is an extension call request signal from the slave unit B. The display is performed, for example, by blinking a light emitting diode.

In step a l 3, the ring tone output from the ring tone generation circuit 8 is transmitted to handset A, and when handset A receives the ring tone in step a l zl, step a ]
, 5 is output from the speaker 12 along with the audio signal received by the base unit 1° via the telephone line 4.

In step a16, it is determined whether the extension key 13 has been pressed in the child mA, and if the extension key]3 has been pressed, the process advances to step a1.7. In step 2t]7, an incoming call response signal is transmitted from the handset A to the base unit 10, and in steps At ai9, the speednet 1 to work 7 are controlled to hold the connection of the telephone line 4, and at step a20, a hold tone which is a predetermined acoustic signal outputted from the hold tone generating circuit 5 is outputted to the telephone line 4. Step a21 is the communication path switching circuit 6
, the line switch connecting handset A and telephone line 4 is turned off, and the line switch connecting handset A and handset 1fiB is turned on.

In step a22, the base unit] 0 outputs an incoming call response signal to the handset B, and when the handset B receives the incoming call response signal in step a2B, in step a24 the base unit 0 outputs a call response signal to the handset B. The output of the sound is stopped.At this point, the telephone 1 puts the outside call state on hold and sets the extension call state between handset A and handset B.

According to this embodiment, as described in ``2'' below, when handset B requests an extension call interruption to handset A which is in an outside line call state, - the connection with the outside line telephone is set to the idle state. , the extension call status is set.

Therefore, unlike in the past, the state of an outside line call does not suddenly change to a multi-party outside line call state, and there is no possibility that someone else suddenly interrupts the call with the party using the outside line telephone, or that another person cannot hear the contents of the call with the outside line telephone. The user can smoothly listen to the operator's request for interrupting an extension call without being asked.

Further, even if handset A calls handset B while handset B is in an outside line call state, the same operation as in this embodiment is performed.

In this embodiment, a so-called cordless telephone type telephone in which the base unit 0 and the slave unit A1B are connected by wireless communication] has been described, but the base unit and the slave unit are connected by wire. Good too.

In addition, even if an interrupt request for an extension call is made to a handset that is in a multi-party external call state and can set/cancel hold for an outside line phone, the same operation as in the above embodiment is performed. will be held.

Incidentally, in the above-described embodiment, the case where the handsets are connected to each other has been described (although it is clear that the present invention is applicable even if the base unit 0 has the function of a telephone).

Effects of the Invention As described above, according to the present invention, even if an extension call request is made to a terminal device that is in an outside line call state, the outside line multi-party call state is not immediately set as in the conventional case. After the external call state is put on hold, the internal call state is set. This allows an extension call to be made without interfering with the call between the outside line telephone and the terminal device, which is in the state of an outside line call, and prevents the caller on the outside line telephone from being surprised or uncomfortable. Something comes up.
