To prevent market-dependent items to be transacted, such as securities, from being mistaken during telephone orders.

An IVR server 12 provides a customer C who has made a connection via a public line N with the price data of a stock as voice information which the customer has selected from among stock price data stored in a memory 4. When the customer C selects a transaction procedure, a circuit control part 11 and an ACD server 13 connect the line to a telephone 3 dedicated to an operator P in charge of reception. In this case, the stock and the stock code whose price the customer C has checked are displayed in a window 21 on the screen 2a of a terminal device owned by the operator P, to make it possible to receive transaction orders while preventing mistakes with stocks arising from telephone orders between the customers and the operators in charge of reception.
