Thereafter, the voice message of the other party received by the communication circuit 23 from the external line through the telephone lines L3 and L4 is recorded by the voice message recording device 17 via the matching transformer TR (step P), and the message of the other party is completed. Check whether it is true or not (step p1g). When finished, the tone signal Tone 2 is output from the tone generator 29 to the voice message recording device 17, and this tone signal Tone 2 is also recorded (step PL).

The voice messages and tone signals thus recorded from each line during the absence mode are played back as follows.

When the operator switches the mode selector switch 18 to the at-home mode, the selector switch 15 is switched to the microphone 8 and speaker 9 side, and when the voice message recording device 17 is operated to play back, each line is switched after the voice message is played back through the speaker 9. Since the tone signal indicating the voice message is also played back, the line on which the voice message was recorded can be audibly determined. In addition, even in the absence mode, the recorded voice message can be played back by inputting a control signal to the control unit 10 from the external line using the telephone line L, and operating the voice message recording device 17 for playback. For example, you can audibly hear voice messages and recorded lines from your telephone while you are away. In addition, when in home mode, the telephone line is disconnected.

When a calling signal is detected, the line selection relay 27 is switched to the telephone lines L3 and L4, and the ringing of the bell 12 notifies the operator of the incoming call. Thereafter, when the operator takes the handset 7 off-hook, the hook switch 11 is turned on, and the selection switch 14 is switched to the handset 7 side, making it possible to talk on the telephone lines L2 and L4.

When an interfon signal from the interfon line, SL, is detected, the line selection relay 27 is switched to the interfon line, L, side, and the operator is notified by the ringing of the bell 12.

After that, the interfon lines L1 and L are connected in the same way as the telephone line.
It becomes possible to make a call at 2.

Therefore, by adding a function that audibly indicates the telephone function and voice message line to an interfon equipped with an answering function, the answering function can be enabled on interfon lines , L, and telephone lines 1 and L4. It can be utilized. By integrating these multiple functions into an interphone, it is possible to eliminate duplication of functions in conventional telephones with an answering machine function, interphones that also function as telephones, etc., and realize multifunctionality at low cost.

In this embodiment, the tone signals Tone 1 and Tone 2 are added after the other party's voice message ends, but they may be added before the voice message. Furthermore, the tone signals Tone 1 and Tone 2 may be in any form as long as they are audible, such as those using frequencies, modulated ones, voice synthesis, human voices, etc. Of course. Furthermore, although two types of tone signals are used, if one tone signal is added to only one line, the cost of the negative layer can be reduced.
