Communication control method for notifying calling telephone number, terminal device and recording medium

A communication control method for a calling telephone number delivery for connecting a telephone that is connected to a communication control device to a telephone line, the method comprising the steps of:

• providing connection switching means for making or breaking a communication path between the telephone and the telephone line and means for detecting the off-hook of the telephone;
• and
• making the communication path between the telephone and the telephone line when detecting the off-hook of the telephone.

A communication control device that is connected to a telephone line, comprising:

• connection switching means for making or breaking a communication path between a telephone and the telephone line as well as between a data processing device and the telephone line;
• communication path control means for making a communication path between the telephone line and the data processing device at a call so that the data processing device can receive the call, and for issuing periodically a notice for inquiring of the data processing device about its operational state, and for making the communication path between the telephone line and the telephone when a response to the notice is not received in a predetermined time.

A communication control method for plural terminal devices that are connected to a telephone line to receive a call with a calling telephone number from the telephone line without a contention, the method comprising the steps of:

• providing a master terminal device that is a terminal device connected directly to the telephone line with connecting means for transmitting a calling telephone number reception sequence that is executed between the telephone line and the other terminal device;
• monitoring the calling telephone number reception sequence in the terminal device during execution of the calling telephone number reception sequence between the telephone line and the other terminal device, so as to obtain the calling telephone number.

A terminal device that is connected to a telephone line, comprising:

• connecting means for connecting the telephone line with the other terminal device and for detecting a signal that is transmitted between them so as to output the detected signal;
• and
• monitoring means for monitoring the calling telephone number reception sequence that is executed between the telephone line and the other terminal device so as to obtain the calling telephone number in accordance with the detected signal.

A computer readable recording medium storing a program for executing a communication control method for plural terminal devices that are connected to a telephone line to receive a call with a calling telephone number from the telephone line without a contention, the program controlling as follows:

• when setting means that is provided in a master terminal device that is a terminal device connected directly to the telephone line set a calling telephone number reception sequence to be executed in the master terminal device, the calling telephone number reception sequence is executed in the master terminal device, and the connection between the telephone line and the other terminal device is set to a disconnected state;
• and
• when the setting means set the calling telephone number reception sequence not to be executed in the master terminal device, the telephone line is connected to the other terminal device without executing the calling telephone number reception sequence in the master terminal device, and the other connected terminal device executes the calling telephone number reception sequence.
