DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram for explaining an outline of a key telephone apparatus having a function of releasing a held state in the case of an extension of the key telephone apparatus. Reference numeral 1 denotes a key telephone device, which has a signal transmitting / receiving circuit 2, a terminal control circuit 3, a voice mail device 4, a speech path switch 6 for switching subscriber lines and trunk lines, a speech path switch control circuit 7, and a voice mail control circuit 13. doing. The holding telephone 11 and the held telephone 12 are connected to the signal transmitting / receiving circuit 2. The voice mail device 4 is connected to a communication path switch 6 of the key telephone device 1. The voice mail control circuit 13 controls the voice mail device 4.

The held state is released by a button operation or a PB signal from the held telephone 12, and the held telephone 1 is released.
2 and the telephone with the holding side telephone 11 are enabled. However, even if the state shifts to the call-enabled state, if the holding party has not returned to the seat, the call cannot be made. In other words, there is no response from the hold telephone 12 to the hold telephone 12. If the holding side is not the holding side telephone 11 until a predetermined time elapses after the held state is released, the telephone line of the held side telephone 12 is switched by the voice mail control circuit 13 Connected to mail device 4. The holdee can accumulate a message such as “I'm done with my business” or “I can't wait anymore” in the voice mail device 4. The stored message is automatically sent from the voice mail device 4 to the hold side, or the hold side can call the voice mail device 4 to listen to the message addressed to the user. In this way, the held party can disconnect the telephone line after notifying the holding party of his / her intention so as not to be rude. The presence or absence of a response from the holding telephone 11 is detected based on an ON / OFF signal of a hook switch of the holding telephone 11 or a sound input level to a microphone of the holding telephone 11. Although not shown, a response detection circuit for detecting the presence or absence of a response from the holding telephone 11 can be provided in the telephone itself or the signal transmission / reception circuit 2.

FIG. 2 is a block diagram for explaining an outline of a key telephone apparatus having a function of releasing a held state when the held side is an extension via a public line or a private branch exchange. Elements denoted by the same reference numerals as those in FIG. 1 indicate the same elements, and the description thereof will be omitted. The key telephone apparatus or the private branch exchange 5 includes a telephone line switch 6 for switching a subscriber line and a trunk line, a telephone line switch control circuit 7, and a PB from a hold telephone 12 via a public line or a private branch exchange internal line.
A PB signal detection circuit 8 for detecting a signal and a voice mail control circuit 13 for controlling the voice mail device 4 are provided. Further, the voice mail device 4 is connected to a telephone line switch 6 of a key telephone device or a private branch exchange 5.
