Abstract

PURPOSE:To make is possible to transfer an incoming call to an extension number etc., at the time of the incoming call again by storing a stored caller number and the extension number which finally became a calling state, etc., in a communication device receiving and storing the caller number notification information of an ISDN. CONSTITUTION:When the caller number notification information from a transmitter is reached, a caller number/extension number storage part 4 is checked and the same caller number is automatically transferred to the pertinent transfer destination extension number if such a number exists. At this point, if plural extension numbers corresponding to this caller number exist, the number of highest frequency is given top priority. Thus, also when the transmitter is a facsimile equipment, if a manual transfer to the facsimile equipment of the extension is performed in a key telephone system only first, the subsequent incoming call from the same telephone number becomes possible to be automatically transferred. When the manual transfer is performed after the termination of a call, the extension number is made to be stored in this caller number/extension number storage part 4. Therefore, when an incoming call exists in the communication between communication devices, in particular, the communication without any manual work and without taking time, etc., is performed.
