Embodiment Construction

[0015] Figure 1 shows a structure in which the process of the present invention can be used. A directory reference device ENQ is connected to a terminal TER in which speech is transmitted via the channel BCHAN and data via the channel DCHAN. The channel BCHAN can be, for example, a B-channel in an ISDN (Integrated Services Digital Network) line, and the channel DCHAN can be a D-channel or another B-channel in the same ISDN line. However, it is also possible to use analog voice to connect to the channel BCHAN to realize the voice connection between the directory inquiry device ENQ and the terminal TER, and the channel DCHAN can also be an in-band signaling channel. Audio Multi-Frequency) transmission.

[0016] If the user of the terminal TER is now looking for a telephone number, he should initiate a conversation with the directory inquiry device ENQ as usual. The terminal TER makes a voice connection with the voice device VOICE through the channel BCHAN, so as to realize voi...
