Similarly, a plurality of telephone accommodation numbers are assigned to one extension number, and the contents are stored in the telephone accommodation storage table section 106. On the other hand, as shown in FIG. 3, the telephone status management table section 107 stores a table for use status management for managing the status of extension numbers and incoming call priority management for specifying telephones to receive prioritized calls.

Next, the operation of the above embodiment will be explained with reference to FIG. In the above embodiment, the key telephone 101a has the accommodation number "10", and the standalone telephone 101b has the accommodation number "26".
”, each with the same extension phone number (e.g. 2
01). Temporary button telephone 101a
Suppose that the user makes a 0FF-HOOK call. This transmission information is detected by the extension subscriber circuit section 102a and transmitted to the common control section 105. The common control unit 105 first performs step 1 in FIG. 4 using information from the extension subscriber circuit unit 102a.
identifies the accommodation number "10" of the button telephone 101a, and stores this accommodation number "10" in the telephone accommodation storage table section 1.
06, and the telephone accommodation storage table section 106 uses this information to select the corresponding extension number "201 J" in step 2.
is searched for and sent back to the common control unit 105. The common control section 105 transmits this extension number information to the telephone status management table section 107. Telephone status management unit 107
As shown in Fig. 3, status data, that is, status management information of the extension number is stored corresponding to the extension number.
This status data information is returned to the common control unit 105, and the common control unit 105 uses the returned data to execute the outgoing connection process of the button telephone 101a in step 4 if the status is Idle (vacant) in step 3. Then, the status is converted into Busy (in use) data and stored in the telephone status management table section 107. When the outgoing connection process is performed, the button telephone 101
A is connected to other extension telephones via the extension subscriber circuit section 102a and the call connection section 103, or is further connected to an external telephone via the office line 108 via the office line circuit section 104. In step 3, the status reply data is Busy.
(In use) means that another corresponding telephone, that is, the standalone telephone 101b, is in use, so in step 5 the BT
As a process, a busy tone, that is, a busy tone, is sent to the key telephone 101a.

On the other hand, when making a call by off-hooking the stand-alone telephone 101b, the extension subscriber circuit section 102b detects this, and the outgoing connection process or BT process is subsequently performed in exactly the same manner. In this way, it is possible to make a call from any telephone without performing any special operations such as switching operations.

As shown in the incoming call processing flow in the figure, when an incoming call is activated to the corresponding extension, the extension number is identified in step 1, and the common control unit 105 identifies the corresponding extension from the telephone status management table 107 in step 2. The status data of the number is checked, and if the status is Idle, in step 3, the information on the receiving side telephone accommodation number designated as priority at that time is searched and received, and in step 4, the priority information received from the telephone status management table section 107 is received. The incoming call is sent to the corresponding key telephone 101 via the extension subscriber circuit 102a of the receiving telephone accommodation number, for example, the accommodation number "10" of the key telephone 101a.
The incoming call to a is processed, and at the same time, the status data information is recorded as an incoming call and stored in the telephone status management table 107.

If the status information received in step 2 is Busy, processing is performed as disconnected. In this way, incoming calls can be given priority to the telephone set that has been designated as a priority in advance.

Note that multiple telephones 101a, without specifying priority incoming calls,
It is also possible to have all 101b receive calls at the same time.

In this way, by providing each table information in the telephone storage storage table section 106 and the telephone status management table section 107, it is possible to make an outgoing call from any telephone without performing a switching operation, and also receive a call based on the table information. You can receive calls to a designated phone. Therefore, when making a call, the functions of the button telephone 101a such as speed dialing of the button telephone 101a can be fully utilized. Also, when receiving a call, if you set the incoming call priority to the standalone telephone 101b by connecting a telephone number, fax, etc. to the standalone telephone 101b,
