The present invention is designed such that in a communication apparatus under a control of a switching communication apparatus, a telephone transmission can be done by using a telephone directory data within the switching communication apparatus which is not registered in a telephone directory within the communication apparatus. When, a signal indicative of a usage of a telephone directory data is inputted to a terminal controller 1a from a telephone directory process recognizer 1c, the terminal controller 1a transmits a telephone directory data stored in an in-terminal telephone directory memory 1b, to a switching communication apparatus 2. Then, a telephone directory comparator 2d compares a telephone directory data received from a communication terminal 1 with a telephone directory data stored in an in-switching-communication-apparatus telephone directory memory 2d, and stores a telephone directory data, in which the telephone directory data of the communication terminal 1 and the telephone directory data of the switching communication apparatus 2 do not overlap with each other, in a transmission telephone directory memory 2c. Moreover, a central controller 2a transmits the telephone directory data stored in the transmission telephone directory memory 2c to the communication terminal 1. Consequently, the communication terminal 1 can carry out the telephone transmission by effectively using the telephone directory data within the switching communication apparatus 2.
