  The present invention relates to a cordless telephone device such as a cordless telephone having an extension automatic answering function or a facsimile machine having a cordless telephone function when an extension is received. In particular, when a master calls a slave, a call signal A cordless telephone device that includes information indicating whether only an extension call or a slave-specific call is included, and the extension automatic answering function is disabled in the slave unit when an extension simultaneous call is received from the master unit It is about.

  Conventionally, in offices and homes, in addition to fixed telephone devices such as subscriber telephones connected to the public line network, cordless telephones composed of a master unit connected by a wireless communication function and one or more slave units have been widely used. ing. In recent years, cordless telephone devices having a facsimile function in a base unit have also become widespread.

  Recently, digital cordless telephones and digital cordless telephone systems have been provided as alternatives to analog cordless telephones. A digital cordless telephone system is generally called a personal handy phone (PHS), and such a digital cordless telephone is a base unit installed in a home or office, or a public installed outside. There are a self-managed mode and a public mode for communicating with a base station, but there is also a communication mode between slave units in which slave units communicate directly like a transceiver.

  The digital cordless telephone system includes a main unit (switch), a plurality of master units, and a plurality of slave units. The main unit (switch) is connected to a public telephone line network and is connected to a plurality of master units via an ISDN line. And each master unit communicates with the slave unit by using the same frequency F1 to transmit and receive differently in time, and directly communicates between slave units without going through the master unit. it can.

  In such a cordless telephone apparatus, when calling a child device from the parent device, as shown in, for example, Patent Document 1 (Japanese Patent Laid-Open No. 5-30026), a child device designation call that designates and calls a specific child device And, it is possible to select an extension simultaneous call that calls all the slave units at once by button operation. And, for example, when a call specified from a slave unit and a general call to an extension are transferred to a designated person, for example, when a call received from the outside is transferred, if the location of the person is known, the slave unit designated call function is used. If you call only the handset at that location and you don't know where that person is, you can use the extension simultaneous call function to call all the handsets at once.

Furthermore, as a cordless telephone device, as disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 5-83338), a handset-free speaker can be provided in a handset by providing a loudspeaker separately from the handset. It is also known that an extension automatic answering function is provided in which an extension call response is automatically performed by operating a hands-free call function on the slave unit side when an extension call is received from the machine side.
