Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention pertains] The present invention relates to an office telephone exchange, such as a private branch exchange, having a camp-on function.

[Description of prior art]

One of the functions of the central branch relay board of a private branch exchange is a camp-on function, and what is usually called automatic camp-on is used.

To explain the operation of this automatic camp-on, if the extension called party who should be the other party of the call received from the central office line caller to the exchange is busy, the relay station with the camp-on function makes the central telephone party wait. Press the telephone key above to enter the automatic camp-on function.

Upon entering automatic camp-on, the exchange automatically monitors the called extension and immediately sends a ringing signal to the called extension as soon as it becomes available, and also sends a ringing signal to the called extension, and not to the central caller. A tone is sent out, and when the called party answers the extension, the two parties are connected.

This automatic camp-on system suddenly sends a ring tone to the central line caller when the extension callee's line becomes free, which is too bureaucratic and polite to the central line caller. It has the disadvantage of causing discomfort due to the loss of

For this reason, semi-automatic rather than fully automatic camp-on functions are generally known. in this case,
While the automatic camp-on function directly sends a ring tone to the central line caller when the line is connected, semi-automatic camp-on calls the central telephone relay stand and sends a ring tone to the central telephone caller via the switchboard. The connection operation is performed after notifying that the call will be connected to the external line and, in some cases, also informing the called party of the extension that there is an incoming call from an outside line.

To explain this in more detail using diagrams, the first
The figure is a connection pattern diagram showing the operation of a conventionally used camp-on function. From the central office line calling party 102 to the exchange 10
When a call arrives at No. 3, the call first arrives at a central office line relay stand (hereinafter referred to as "relay stand") 105. In this case, the connection path is 1
The connection is as shown in 04. Here, the switchboard responds to the central line calling party 102, asks for the number of the extension called party 101, and establishes a connection. The connection path in this case is indicated by 107. In this case, if the called party 101 on the extension side is busy, this is usually communicated to the central line calling party 102, and the central line is kept in a hold state to make it wait. When the extension called party 101 becomes available, the central office line calling party 102
After calling again and talking about connecting to the extension, and then calling the extension and telling them that you would like to connect to the outside line,
A central office line calling party 102 and an extension called party 101 are connected. In this case, connection paths 107 and 104 are both temporarily connected, resulting in a three-way communication state.

Although this connection method is polite, it increases the burden on the switchboard operator as he constantly monitors the busy indicator and waits for the called extension to become free, and it is inefficient and does not allow automatic camping. The labor-saving significance of the on function is lost.

[Purpose of the invention]

The present invention solves the above-mentioned drawbacks, and makes it possible to inform the caller of the central office line that the caller will be connected to an extension line without going through a switchboard when connecting a line using a camp-on operation. To provide an office telephone exchange capable of performing human-friendly automatic call and jump-on without impairing the labor-saving effect of automatic camp-on.

[Features of the invention]

The present invention includes a voice response device in the exchange that generates a predetermined message, and provides a camp-on operation to the central office line calling party before entering into the connection between the central office calling party and the extension called party. For example, when connecting a line, the voice response device generates a common phrase such as ``Sorry to have kept you waiting. I will connect you.'' This is sent to the central line caller, and then It is characterized by establishing a connection between a calling party and a called party.

[Explanation based on examples]

Hereinafter, the present invention will be explained based on the drawings.

FIG. 2 and FIG. 3 are diagrams showing a device according to an embodiment of the present invention and its connection pattern.

In FIG. 2, 202 is a central office line calling party, 201 is an extension called party, and these are connected to an exchange 203. Furthermore, the exchange 203 includes a voice response device 204 and a relay stand 205.
is connected. The voice response device 204 is a device that stores fixed text information such as "Sorry to have kept you waiting. I will connect you." The voice response device 204 is a device that stores fixed text information such as "Sorry to have kept you waiting. I will connect you." The message is configured to be able to be sent to the calling party 202. The voice response device 204 is a random access memory (R
AM) and high-speed disks are suitable.

Next, the operation of the above embodiment device will be explained.

In FIG. 2, a call from a central office line caller 202 is sent to
03, the incoming call further passes through the connection path 210 and arrives at the relay stand 205, where the operator responds and asks for the number of the extension called party 201, etc.

At this time, if the called party 201 on the extension line is busy, the switchboard informs the calling party 202 of the central office line to that effect, puts the central line on hold and makes the telephone caller 202 wait, and uses the specified phone key for automatic camp-on on the relay stand 205. Press to enter automatic camp-on operation.

FIG. 3 is a diagram showing a connection pattern after the extension called party 201 becomes idle.

In FIG. 3, since the exchange 203 is in an automatic camp-on state, the relay console 205 is disconnected and has no relation to communication for incoming calls.

When the extension called party 201 becomes free, the central office line calling party 20
A connection path 211 is formed between the voice response device 204 and the voice response device 207, and the voice response device 204 sends a message to the central office line caller 202, which is a common phrase used in such cases: ``Sorry for keeping you waiting.''I'll connect you. ” and other words. After this, the connection path 211 is disconnected, and a connection path 212 is formed in its place, connecting the central office line calling party 202 and the extension called party 201, and communication becomes possible.

Note that when connecting the line, the connection path 212 is not immediately formed, but a logical connection is first made, a paging signal is sent to the extension called party 201, and the central line calling party 202 is After being connected to the calling signal trunk, when the extension called party 201 answers, a connection path 212 is formed and a physical connection is established.

As explained above, by using the present invention, it is possible to speak to the caller prior to automatic camp-on, so that the caller is not rude. Furthermore, after the operator has performed the automatic camp-on operation, he or she can leave the connection operation, thereby eliminating the need to monitor the busy display, which greatly contributes to improved efficiency.
