Abstract

PURPOSE:To avoid a talker from being kept waiting for a long time while being in the talking connection state by sending a signal tone capable of being listened to sufficiently even if a receiver is parted from the ear to a telephone set during talking by the operation of the called party, thereby urging the restart of the talking to a talking party leaving the handset remote. CONSTITUTION:While an A extension telephone set 3 and a B extension telephone set 4 are communicated with each other, if the talker of the telephone set 4 leaves its seat for the purpose of, e.g., checking something while leaving its handset on a desk or the like, and the talker of the telephone set 3 requires to stop the communication due to urgent business and applies telephone operation such as hooking, then a central controller 1 controls the switch 2 so as to interrupt a speech path composed of the telephone set 3, an intra-office trunk 5 and a speech path composed of the intra-office trunk 5 and the telephone set 4 respectively and connects the telephone set 4 and an audible signal tone trunk 6. Thus, an audible signal tone reaching a location parted from said telephone set 4 is generated from the telephone set 4, and the talker of the telephone set 4 listening to it returns immediately to its own seat and hooks the handset, then the talking is restarted with the talker of the telephone set 3 for the required ordering.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for resuming a call in an automatic exchange, and in particular, when one party to a connected telephone interrupts the call and leaves the telephone, the other party The present invention relates to a call resumption method that can prompt a call from someone.

(Prior art) When the person called by phone happens to be away for a while and the person receiving the call goes to look for him while the call is still connected, or when the other party interrupts the call for some reason during the call, Traditionally, when someone leaves the phone, the person making the call has no way of communicating their intentions to the other party through the same phone; they have to either hang up and call again, or use another phone. The only way to deal with the situation was to have the person who answered the phone communicate our intentions.

(Problems to be Solved by the Invention) As mentioned above, when talking on the telephone, it is common to interrupt the call and take the handset away from one's hand to look up something. , for example, even if the other party wants to end the call, they cannot contact the other party, so they have to wait impatiently, which is very inconvenient. There was also a problem that it was too long.

(Means for Solving the Problems) The call resumption method according to the present invention is provided with a means for transmitting a signal sound that can be clearly heard even when the telephone receiver is removed from the user's ear. The system sends an audible signal tone to prompt the caller who has hung up the handset to resume the conversation.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram of a telephone exchange for intra-office calls, and FIG. 2 is a schematic diagram of the embodiment shown in FIG. 1 in an audible tone transmission state. As with normal automatic exchange machines,
The local trunk 5 is connected via the tongue switch 2,
These are controlled by the central control unit 1; in addition to this, according to the invention, an audible signal trunk 6 is connected to the switch 2. This audible signal tone trunk 6 is connected to the extension telephone 3 or 4 so that an audible signal tone is emitted from the telephone receiver (handset) to the outside.

As shown in FIG. 1, it is assumed that while A-extension telephone 3 and B-extension telephone 4 are talking, the caller of B-extension telephone 4 leaves his/her seat, placing the handset on the desk or the like to do some research. On the other hand, it is assumed that the caller on extension A telephone 3 needs to terminate the call midway due to urgent business. At this time, when the caller on the A extension telephone 3 performs a telephone operation such as hooking, the central control unit 1 connects the A extension telephone 3 and the local trunk 5, and the own internal trunk 5 and the B extension telephone, as shown in FIG. controlling switch 2 to disconnect each of the communication paths of 4;
And the B extension telephone 4 and the audible signal tone trunk 6 are connected. As a result, the B extension telephone 4 emits an audible signal sound that can be heard far away from the telephone, and the caller on the B extension telephone 4 side who hears this immediately returns to his/her seat and hooks up. Then, the call is resumed with the party on the A extension telephone 3 side, and necessary discussions are held with each other. The above example is for a case where the person on the B-extension phone leaves the call during a call, but if the caller on the A-extension phone temporarily leaves the phone midway through the call, an audible signal will be sent to the A side by the operation of the B-side caller. can be sent.

(Effects of the Invention) As explained above, according to the present invention, even if the other party leaves the telephone during a call, it is possible to convey any intention to the other party, and even if the other party is temporarily away, Even when a responder is on call, it is possible to communicate with the responder. This eliminates the frustration of having to wait for a long time while the call is connected, and the other party does not have to worry about the call being disconnected without permission while the other party is away from the call, allowing both parties to use their time more efficiently. It will be done.
