That is, when the read call processing data is data corresponding to the call connection restriction (S211), the guide message stored in the database 17 is read, output to the quantization and speech conversion processing unit 18, and the quantization and The voice conversion processing unit 18 converts and outputs a guide message S223, which is voice data, into a voice signal. The guide message is a call requester such as "Currently there is a large volume of calls. That is, it is preferable to use indirect expression in consideration of the sender's emotion.

In addition, when the read call processing data is data corresponding to the time conditional call connection (S212), the current time is detected (S216), and compared with the call connection restriction time stored in the hard disk (16) (S217). In the case of the limited time, the guide message is output as described above (S223), and when the comparison result (S217) does not correspond to the call connection limited time, the series of operations described above with reference to FIG. S221) to make a call connection is made.

In addition, when the read call processing data is data corresponding to the voice mail box connection S213, the voice mail guide message stored in the database 17 is read and output to the quantization and voice conversion processing unit 18. The quantization and voice conversion processing unit 18 converts and outputs a voice mail guide message S214, which is voice data, into a voice signal. The voice mail guide message is "voice mail service. If voice recording is desired, recording with a beep sound is required. And press # to save the recording. Thereafter, the received voice signal is converted into voice data by the quantization and voice conversion processing unit 18 and stored in the database 17 in association with the call number requested to connect to the call (S215).

Therefore, when the call connection request telephone number is a telephone number of a landline telephone (TP) subscribed to a plurality of telephone number usage services, the landline telephone switch EX can identify a specific telephone number for which the call connection is requested. While transmitting a unique ring signal to the wired telephone TP, it is possible to provide a conditional call connection service as described above.

On the other hand, Figure 4 shows the configuration of the landline telephone (TP) according to the present invention, selectively the signal transmitted from the landline telephone switch (EX) in accordance with the on / off (On / Off) of the Hook button (Hook) A hook switch 21 for outputting; A bell (25) informing a ring tone that a call is received according to a ringing signal transmitted and output through the hook switch; A microphone 24 for converting and outputting a user's voice into an electrical signal; A speaker 23 for outputting a voice signal received through the hook switch as voice; Transceiver separator 22 for separating the signal received and transmitted through the hook switch; A dial key 29 for inputting a telephone number desired by a user; A dual tone modulation frequency (DTMF) generator 26 for outputting a signal corresponding to the telephone number selected by the dial key as a signal in the form of a frequency; A pulse generator 27 for outputting a signal corresponding to the telephone number selected by the dial key as a pulse type signal; And a microcomputer 28 for controlling the operation of the DFM generator or the pulse generator by a selection terminal E / M that selects a dialing method as mechanical (M) or electronic (E).
