Abstract

PURPOSE:To allow a called extension to recognize a dialing to be a redialing when a caller extension redials the called extension by selecting a call tone sent from a dial means to the called extension based on a stored content when a call comes from the caller extension to the called extension. CONSTITUTION:When a controller 3 detects hook-off of an extension 2j by an extension circuit 10, the controller connects a numeral reception section 11 to the extension 2j to reach the numeral reception state. Upon the receipt of an extension number of the extension 2j dialed by a caller of the extension 2j (state 1), the controller 3 checks whether or not the extension 2j is idle, and when the extension 2j is idle, the controller 3 checks whether or not the information of the extension 2j is stored in a relevant location of a caller extension storage area of a storage device 4 to the extension 25, and when the recognition information of the extension 2j is not stored, a ring back tone transmission trunk 8 is connected to the extension 2j to send a ring back tone to the extension 25 and a 1st call tone transmission trunk 5 is connected to the extension 2j to send a 1st call tone to the extension 2j.

。In this extension calling method, a special number is assigned to each extension to identify the extension by the ring tone, and the calling extension issues the special number, dials the called extension number, receives a ringback tone, and then calls the extension. When a number for identifying the self is dialed, the calling signal generating circuit causes the called extension to send out a ring tone in synchronization with the dial pulse of the number for identifying the self, A different bell rings for each calling extension, allowing the caller to be identified.

がある。(C) Problems to be Solved by the Invention However, in the conventional extension calling method described above, after the called extension is busy or the called extension does not respond, the calling extension calls the called extension again. In some cases, it is possible to make the called extension recognize that it is a re-ringing by assigning the above-mentioned re-ringing to one of the numbers for self-identification in advance. In addition to the number, it is necessary to dial a special code and a number for self-identification, which poses a problem in that the operation is complicated for the caller. Another problem is that it takes time to complete a call.

本発明は、上記問題に鑑みて為されたものであり、容易

In this case, the system is equipped with a storage means for storing information on the calling extension, and a ringing means for sending a plurality of types of ring tones to the called extension, and when a call is received from the calling extension to the called extension, the information is stored in the storage means. This extension calling method is characterized in that a ring tone to be sent from the calling means to the called extension is selected based on the contents of the call.

ダイヤルするだけでよい。(E) Effect According to the present invention, when a call is received from the calling extension to the called extension, a ring tone to be sent from the calling means to the called extension is selected based on the contents stored in the storage means. Therefore, if you want the called extension to recognize that it is ringing again when the calling extension calls the called extension again after the called extension is busy or the called extension does not answer, the number of the called extension All you have to do is dial the number.

Enters numeric reception state. Then, when the extension number of extension 21 dialed by the caller of extension 2j is received (state 1),
The control device 3 checks whether the extension 21 is free or not, and if it is not free, stores the information about the extension 2j (specifically, inside 112) in the position corresponding to the extension 21 in the calling extension storage area of the storage device 4.
(extension number), starts the timer 9, connects the busy tone trunk 7 to the extension 2j, and sends out the busy tone to the extension 2J (state 2).

I! 1 ring tone (state 1!3). On the other hand, if the identification information of extension 2J is stored, the ringback tone sending trunk 8 is connected to extension 2J, and the ringback tone is sent to extension 2J, and the second ringback tone exit trunk 6 is connected to extension 21. The connection is made and the second ring tone is sent to extension 21 (state 5).

。In the above embodiment, the timer 9 is used to erase the memory contents of the calling extension storage area after a certain period of time.
For example, if information for extension 2 is stored in the stable at the location corresponding to extension 21 in the calling extension storage area, and a new call is made from extension 2k to the currently busy extension 21, the call is Write the identification information for extension 2 in the extension storage area at the position corresponding to extension 21! (that is, override). This makes the timer 9 unnecessary.

It is possible to adopt both a configuration in which one calling extension is stored and a configuration in which a plurality of calling extensions are stored. In such a case, by preparing three or more types of ring tones and selecting the ring tone according to the number of times, more detailed services can be provided.
