Abstract: PROBLEM TO BE SOLVED: To warn a user about the snatching of transmission by providing a processor which transmits a message to a terminating system to show that the transmission is received via an unsafe link. SOLUTION: An originating system such as a cable set top box 134 receives dialed figures that identifies a called subscriber (e.g. a user receiving service from a personal computer 126). Then the originating system sets up a call path to the called subscriber. When the call path includes an unsafe link, a question is sent to a terminating system to decide whether the system of the final destination can process an enciphered message. In this example, an ISP server 120 gives a question to a DSP 128 to decide whether the DSP 128 has the reading capability. When the DSP 128 has no reading capability, the originating system gives warning to a calling subscriber using a telephone set 138 about the unsafe transmission.

Abstract: PROBLEM TO BE SOLVED: To obtain a system and a method by which a customer executes communication with a company by means of bi-directional voice while being connected to the Internet by connecting a telephone exchange to a network site with a communication network and establishing an inter-point path between the exchange and the network site. SOLUTION: A communication signal from the telephone exchange 110 is transmitted to a network server 120 having the network site 125 through the communication network 115 and communication is executed with a computer 105 which is connected to the exchange 110. The telephone exchange 110 is connected to the network site 125 with the communication network 115 and communication over the inter-point path (communication line 145) between the exchange 110 and the network site 125 is established. Thus, telephone connection from the computer 105 to the network site 125 through a communication link 145 is attained.
