1. A communication terminal apparatus connected to a communication network through a data channel for transfer of line transaction data or packet transaction data and through a signal channel for control of a call from a transmitter to a communication destination party, the apparatus comprising:

  • a first memory for storing previously registered predetermined caller identification data to be transmitted through the communication network and the signal channel;

    a second memory for temporarily storing received caller identification data each time the communication terminal apparatus receives caller identification data transmitted through the communication network and the signal channel from the transmitter;

    a third memory for temporarily storing therein transaction data received through the communication network and the data channel;

    a fourth memory for storing previously registered receiver registration identification data corresponding to a plurality of destination communication terminal apparatuses, to which the transaction data from a communication terminal apparatus associated with one of the caller identification data stored in the first memory is to be transmitted, the receiver registration identification data being stored in one of a one-to-one relationship, a one-to-plural relationship, and a plural-to-one relationship with the predetermined caller identification data stored in the first memory;

    first control means for comparing the predetermined caller identification data stored in the first memory with the received caller identification data temporarily stored in the second memory, and for transmitting the transaction data to the third memory upon detection of a coincidence between one of the predetermined caller identification data and the received caller identification data;

    second control means for automatically calling one of the receiver registration identification data stored in the fourth memory corresponding to the coincided predetermined caller identification data; and

    third control means for automatically transferring the transaction data stored in the third memory to one or more of the plurality of destination communication terminal apparatuses associated with the receiver registration identification data,whereby the transaction data is transferred between the transmitter and the one or more of the plurality of destination communication terminal apparatuses with the communication terminal apparatus functioning as a relay station in accordance with the relationship between the transmitter and the previously registered receiver registration data stored in the fourth memory.
