When a speech is finished and an extension line is restored, it reads the extension number of the extension telephone set 6 to be called stored in the storage device 3, and connects between the calling extension telephone set 4 and the extension telephone set 4 and the extension telephone set 6 to be called so as to turn them into a speaking state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an extension series call system in a storage program controlled automatic exchange.

[Conventional technology]

Conventionally, the extension series call system in storage program-controlled automatic exchanges is used when the user of a calling extension telephone wants to continue calling the users of other extension telephones after the end of the call. After restoring the
The method was to call and dial again.

[Problem that the invention seeks to solve]

In the conventional method described above, the user of the calling extension telephone calls the users of two or more extension telephones in succession without operating the calling extension telephone in order to restore the extension to the calling extension telephone. Since there is no means to do so, the user of the calling extension telephone must dial the extension number of the next called extension telephone after restoring the extension of the calling extension telephone after the call ends.

[Means for solving problems]

In the extension series call system of the present invention, the extension numbers of multiple called extensions are registered in advance from the calling extension in a storage device, so that the user of the calling extension can select the first called extension. End the call to the extension phone, and
When the extension of the called extension telephone is restored, the calling extension telephone and the second called extension telephone are placed in a communication state, and the conversation with the user of the second called extension telephone is terminated.

The apparatus has a means for automatically connecting the called extension telephones corresponding to the extension numbers registered in the storage device in sequence.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a relay system diagram of an embodiment of the present invention.

In FIG. 1, 1 is a communication path switch, 2 is a central control unit, 3 is a storage device, 41 is a calling extension telephone, 5 and 6 are
is the called extension telephone. First, a method for setting an extension series call from the calling extension telephone 4 will be explained.

In FIG. 1, the calling extension telephone is taken off-hook and the special number for setting up an extension series call is dialed. The central control unit 2 learns from this dialed special number that an extension series call is set up, and dials the registered number of the called extension telephone and the extension number of the called extension telephone to the calling extension telephone 4. A message is sent to the calling extension telephone 4. When the calling extension telephone 4 dials the registered number of the called extension telephone and the extension numbers of the called extension telephones 5 and 6 according to the order of extension series calls,
The central control unit 2 stores the registered number of called extension telephones and the extension numbers of the called extension telephones 5 and 6 in the storage device 3, and completes the setting of the extension series call. The central controller 2 sends a message to the calling extension telephone 4 that the setting of this extension series call has been completed, and then connects the calling extension telephone 4 and the called extension telephone 5. to establish a call between them. The central control device 2 monitors the status of the called extension telephone 5 that is connected to the calling extension telephone 4, and determines when the call between the user of the calling extension telephone 4 and the user of the called extension telephone 5 has ended. When the extension on the called extension telephone 5 side is restored, the extension number of the called extension telephone 6 stored in the storage device 3 is read out, and the calling extension telephone 4 and the called extension telephone 6 are connected to each other. into a call state.

The order of connection of the called extension telephones 5 and 6 follows the dialing order of the extension series call setting. If the user of the calling extension telephone 4 wishes to cancel the extension series call setting, the extension series call setting is canceled by putting the calling extension telephone 4 on-hook.

〔Effect of the invention〕

As explained above, in the present invention, when the user of a calling extension telephone wants to communicate with the users of a plurality of called extension telephones in sequence, the extension numbers of the plurality of called extension telephones are registered in advance. By doing so, when the user of the calling extension telephone wants to talk to the user of the next called extension telephone, the user of the calling extension telephone does not have to make a call again from the calling extension telephone, and can use the next called extension telephone. This has the effect of making it possible to talk to other people.
