Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention is a supplementary service of a private branch exchange capable of connecting an incoming call to a local line by dial-in, and a called party (called party).
When the user is busy, the present invention relates to a service that automatically returns the caller after the end of the call.

(Problems to be solved by the prior art and the invention) Conventionally, this type of service was realized only on the extension of a private branch exchange, but in a private branch exchange that does not have a dial-in function, all incoming calls to the central office line are relayed. Because of the intermediary of the stand, the operation of the relay stand operator is required in order for the called party corresponding to an incoming call from the central office line to be busy and for the called party to call back the calling party after the call ends.

In addition, in a private branch exchange equipped with a dial-in function, when the called party corresponding to an incoming call to the central line is busy, first,
Dial the voice mail service special number to register the voice message for the called party in the voice mail system, then go on-hook and off-hook again, then dial the call-back service special number and the caller's telephone number. The private branch exchange registered this calling party number in a separately prepared storage device.

For this reason, the caller must register the caller number after temporarily registering the message message in the voice mail system and then re-calling it to register the caller number, which is disadvantageous in that the operation is complicated. In addition, a storage device for storing the calling party number must be prepared separately, which not only increases the cost of the private branch exchange, but also complicates the program structure and lengthens the processing time.

An object of the present invention is to store a caller's message message and a calling number in individual mailboxes of a voice mail system when the called party corresponding to an incoming line call is busy. Correspondingly stored, when the called party hangs up and becomes empty, the called party is automatically called, the message message registered by the calling party is sent to the called party, and the registered calling party number is sent. It is to provide a method for accumulating a busy message and a caller's call back number to automatically call back a reading reader.

(Structure of the Invention) The busy message and calling party call back number storage method of the present invention is a busy message including a registration guidance message of a calling party call back service in a private branch exchange having a dial-in function. Is registered in advance, and when a called party corresponding to an incoming call to a station line is busy, a message message from the caller of the called station line call to the called party and the registration guide message from the caller. A voice mail system for storing a voice frequency signal of a telephone number of a caller dialed in response to a call, and a location for accommodating a plurality of extension subscribers accommodated in the private branch exchange. Corresponding to the first mailbox number of the voice mail system for storing the message and the voice mail system for storing the voice signal of the telephone number of the caller. A second mailbox number of the system for each of the accommodating positions in advance, and a main memory for storing the accommodating position of the called party who is busy; and the main memory when the busy party of the called party is detected. A device identifies the accommodation location, connects the caller to the voicemail system, sends the busy message to the caller, and sends the busy message in response to the busy message. Receiving the message message, the service special number for registering the call back number, and the caller number, and identifying the first mailbox number corresponding to the accommodation position of the called party from the main storage device. , Storing the message message in the mailbox, and storing the voice frequency signal of the calling party number in the second mailbox when the service special number is identified, and detecting the end of busy of the called party. Then, the mailbox is accessed based on the storage position stored in the main storage device to send the message message stored in the first mailbox to the called party and the second mail. And a connection control processor for controlling the caller to be called back by sending the voice frequency signal stored in the box to a local line through a local line trunk.

(Example) Next, this invention is demonstrated with reference to drawings.

5 is a voice mail system (VMS) connected to an automatic private branch exchange (PABX) 2 via a voice mail trunk (VMT) 4, and 6 is a voice mail system (VM).
S) 5 is a connection control main processor (CPU), and 7 is a main storage device which is controlled by the connection control main processor (CPU) 6 and stores the accommodation position of the extension of the called side.

First, the operation when there is an incoming call from a station line will be described with reference to the flowcharts of FIGS. When there is an incoming call to the private branch exchange 2 from the caller (STA) 1 of the office line by dial-in, the connection control processor (CP)
U) 6 detects this, calls the corresponding called party (STA) 3 by a known method, and detects that the STA 3 is busy (S1), and the busy party provided in the main storage device 7 is detected. The accommodation area of the called party is stored in the caller's storage area (S2), and the STA1 and the voice mail system (VWS) 5 are connected to the private branch exchange 2 via the voice mail trunk (VMT) 4 (S3). . VMS5 is a trunk line trunk (R
To STA1 via TK) 8, "For example, the person you are calling is currently talking. If you have a message, put it after the beeping tone.
If you need to call back, press the pound key (#) after the message and enter your phone number with the push button. Message is sent (S
4) If the called party who is busy needs to call back the calling party as soon as the call ends, tell the calling party of the central line that the calling party's name and telephone number can be registered. Notice. On the other hand, CPU6
Searches the main storage device 7 based on the accommodation position of the called party, and the VMS 5 registered in the main storage device 7 in advance corresponding to the accommodation position.
Read the first and second mailbox numbers of the above, and instruct preparation for accumulating the message and the voice frequency signal (pippoppappa) which is the calling party number in this mailbox. The CPU 6 instructs the VMS 5 to store the message, such as a name, sent from the caller of the station line in the first mailbox corresponding to the accommodation position of the called party detected earlier. The message message is accumulated (S5). The CPU 6 then detects the # signal (S6).
Then, the VMS 5 instructs the VMS 5 to store the voice frequency signal, which is the calling party number subsequently sent from the calling party, in the second mailbox corresponding to the accommodation position of the called party. The voice frequency signal which is the calling party number is stored (S7). In this way, the registration of the message message from the caller of the central office line and the calling number is completed.

Next, the operation in the case where the called party returns the caller of the office line after the call is completed will be described with reference to the flowcharts shown in FIGS. When the CPU 6 detects that the busy STA 3 is in the last empty state (S11), it instructs the reading of the registration information in the mailbox of the VMS 5 corresponding to the accommodation position of the STA 3 (S12), and the VWS 5 Identifies the presence or absence of registration information in the mailbox instructed by the CPU 6 by a known method (S13), and if registration information exists, CP
U6 connects VMS5 and STA3 (S14), and
STA the message messages stored in the mailbox of
