Control to output through (step S47). Accordingly, the subscriber hears the called party information voice request input voice such as "Please enter the called party information voice".

Thereafter, when the subscriber inputs a voice corresponding to the called party information (that is, the called party's voice information registered and stored in the telephone directory of his access point) through the microphone 16, the short-range wireless telephone terminal 10B. Control unit 15 controls the short-range wireless communication connection unit 12 of the incoming callee information voice signal inputted and converted into digital data by the audio signal processing unit 15 via the access point 25A connected in step S45. It controls to transmit to the subscriber access point 20 via the voice call path to the subscriber access point 25A (steps S48 to S49).

The control unit 21 of the subscriber access point 20 that has received the called party information voice signal through the Internet (VoIP network) connecting unit 23 through the short range wireless communication connection unit 22 controls the called party corresponding to the called party information voice signal. The telephone number is retrieved from the telephone directory of the storage unit 24 (step S50).

Then, the control unit 21 of the subscriber access point 20 transmits the inquired telephone number to the access point 25A (step S51).

The control unit 21 of the access point 25A having received the called party's telephone number from the subscriber access point 20 short-circuits the established voice call call with the subscriber access point 20 (step S52), and the called party The telephone number is dialed to the called telephone 70 of the telephone number based on the Internet telephone protocol (VoIP) (step S53). Here, since the Internet telephony protocol is a known technique, detailed description thereof will be omitted.

On the other hand, when the call mode is selected in the called phone 70 (step S54), a call call connection response signal is transmitted from the called phone 70 side to the subscriber access point 25A as a response to the dialing signal (step S54). S55).

The control unit 21 of the subscriber access point 25A, which has received the call call connection response signal, transmits a call call connection OK signal to the destination telephone 70 side (step S56).
