摘要： There is provided a key telephone system for transmitting and receiving a dial number by a peculiar control signal between a main unit and an extension telephone. The system comprises: an extension telephone; a main unit; an analyzing unit for analyzing an audio signal; and a calling unit for calling in accordance with the result by the analysis of the analyzing means. The calling unit generates a dial pulse. When a calling request from the extension telephone is detected, the main unit connects the extension telephone and the analyzing unit. Information generated by an electronic apparatus via which the dial number can be independently registered from an extension telephone of the KTs is analyzed and calling or displaying can be executed.

摘要： A transfer apparatus which calls a predetermined transferring destination number when an incoming call on a communication line is detected. The transfer apparatus compares a calling-party number received on an incoming-call received line with the predetermined transferring destination number, and if they do not coincide, the transfer apparatus calls the predetermined transferring destination number; however if they coincide, the transfer apparatus does not perform transferring operation. Accordingly, meaningless transmission such as to transfer an incoming call received from a calling party who is located in the transferring destination can be obviated.

摘要： A key telephone system having user-friendly electronic directory function in which dialling numbers more than the number of abbreviated dialling numbers can be registered and the number of digits of abbreviated dialling number is maintained to a small number by treating separately an abbreviated dialling data and other directory data upon registration of data. Further, the content of a retrieved directory data can be registered as an abbreviated dialling number. In the system, a necessary number of data can be registered in the directory, and calling operation using an abbreviated dialling number can be made with a fixed number of digits of abbreviated dialling number regardless of the number of abbreviated dialling numbers. Further, registration of abbreviated dialling number can be performed effectively.

摘要： A telephone exchange system accommodates a plurality of central office lines and a plurality of telephones and records a telephonic communication in a recording area shared by the plurality of telephones. When predetermined conditions are satisfied, the recording is played back or transferred. The shared recording area can be utilized effectively by erasing a recording after it has been transferred, and by detecting the presence of a voice during a telephonic communication and starting and stopping the recording operation based upon the results of detection. The time at which a recording has been made can be comprehended in the form of a voice when the recording is played back.

摘要： Two telephone numbers, one for an outside call and one for an extension call, are registered for each of a plurality of one-touch buttons through a procedure the same as that used in placing a call conventionally and without providing new buttons. When an input designating an outside call is made before pressing a one-touch button, the party corresponding to the outside telephone number is called. When an input designating an outside call is not made before pressing a one-touch button, an extension telephone corresponding to the extension call telephone number is called. Since the same one-touch call designating button can thus be used for both an extension call and an outside call, many telephone numbers can be registered with a small number of buttons.
摘要翻译：两个电话号码，一个用于外部呼叫，另一个用于外部呼叫，一个用于分机呼叫，通过与常规放置呼叫而不提供新按钮所用的过程相同的过程，为多个单触按钮中的每一个注册。当在按下一键式按钮之前进行指定外部呼叫的输入时，调用与外部电话号码对应的一方。当在按下单触按钮之前不进行指定外部呼叫的输入时，调用对应于分机呼叫电话号码的分机。因为同样的单键呼叫指定按钮因此可以用于分机呼叫和外线呼叫，所以许多电话号码可以用少量的按钮进行登记。
