Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call holding method for a key telephone apparatus having a hold response function using a park hold button. 2. Description of the Related Art In a conventional key telephone device, when holding a line (external line) received by each key telephone, a hold button on the key telephone is pressed to hold the line. On the other hand, the park hold button is used when the number of office lines is large and cannot be stored in each key telephone. For example, when a specific key telephone to which many office lines are connected receives office line A and transfers this office line A to another key telephone, the park hold button on the key telephone is pressed. For example, when the first park hold button is pressed, the received station line A is held and registered in the first park hold button, and the first park hold button on all key telephones in the apparatus is held and registered. Display. By pressing the first park hold button, the key telephone that has received the transfer notification can make a call with the station line A that has been held. As described above, the park hold button is a button for temporarily registering a "call" on hold for holding, and puts the other party of the call on hold. A park hold button in a conventional key telephone apparatus is used for holding and registering a party on a call from a state where an operator is talking on an outside line or an extension line.
Therefore, in this key telephone apparatus, when it is not known which key telephone in the key telephone apparatus is located near the other party who wants to make an extension call, the following two methods are used to talk with the other party. Tell the extension number of the caller on the private broadcast and have the other party call you to answer the phone. The caller requests the other party to respond to the broadcast using the private broadcast function. After the request, the caller moves to a response waiting state. [0004] However, in the above-mentioned method of calling the other party by private broadcasting, it is necessary to broadcast the extension number of the caller and all the contents of the request, so that the private information of the caller is required. However, there is a problem that it is difficult to hold the broadcast and it is necessary to request a third party to broadcast. In addition, the above-mentioned method has a problem that the operation method is complicated and not so well known to those who use the telephone, and that a plurality of extensions cannot be in a standby state at the same time. [0005] The present invention has been made in view of such a point, and when an extension call with an unknown location is desired, the request is realized by a hold-response operation, which is most commonly used as a key telephone operation. An object of the present invention is to provide a call holding method for a key telephone device.

The feature is that a call is established by extension . In a key telephone apparatus having a park hold button for holding a caller who is talking on an extension or an outside line, the park hold button has a self-hold response function. When a caller makes an extension call to a caller whose location is unknown, put the extension on hold, call the extension caller using the internal broadcasting facility during this time, and the caller enters the same By pressing the park hold button, both extensions are in a call state. As described above, the caller can easily realize the extension call state by the hold response operation of the park hold button with the party whose location is unknown.
Further, it becomes possible to simultaneously enter the standby state for the number of park reservations registered in the key telephone apparatus. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a flowchart relating to the operation of the park hold button in the call holding method of the key telephone apparatus according to the present invention. In the figure, a numerical value following S indicates a step number. S1 to S5 are flowcharts relating to operations on the caller side, and S6 to S8 are flowcharts relating to operations on the response side. [S1] First, the key telephone A is not yet used and is in an on-hook state. [S2] The handset of the telephone A is removed and the on-hook is changed to the off-hook. An extension dial tone is transmitted from the handset. That is, it is in the extension capturing state. [S3] The x number of the park hold button is pressed. The extension dial tone is transmitted again from the handset of the key telephone set A, and the second extension state is established. Further, the park hold button of the number x of all the button telephones in the key telephone apparatus blinks, and a hold display is performed. [S4] The caller dials the broadcast special number and broadcasts "Mr. Y, please respond to the number x of the park hold button" through the in-house broadcast. [S5] The transfer key is depressed to set a broadcast state end command, and the operation shifts to a response waiting state. However, the extension lamp continues to display during acquisition. In this case, a hold tone is transmitted from the handset of the key telephone set A. [S6] At first, the key telephone B is not used yet and is in an on-hook state. [S7] When the called respondent, Mr. Y, picks up the handset of the nearby key telephone B, the key telephone B goes from on-hook to off-hook. An extension dial tone is transmitted from the handset, and the handset enters an extension capturing state. [S8] When the respondent presses the blinking park hold button x on the key telephone B, the key telephone A on the caller side and the key telephone B on the responder enter the extension communication state. Here, the transmission of the hold tone of the key telephone A on the caller side is stopped, and the park hold button x of all the key telephones is extinguished. In the above description of S5, the transfer key is pressed as the broadcast state end command, but the broadcast state end command can be issued by other means. For example, depending on the time setting,
If there is no broadcast within a certain period of time, end the broadcast state, etc. A hold tone is transmitted from the handset of the key telephone set that has shifted to the response waiting state.
