JPS59188265A - Incoming restriction system of audio response unit - Google Patents

Abstract

PURPOSE:To control the number of incoming calls to an audio response unit through the audio response unit by indicating the permissible number of incoming circuits from a host computer. CONSTITUTION:An audio response unit 12 whose restricted number of incoming calls to the audio response unit is indicated by the host computer 11 stores the value in a register 13. The audio response unit 12, on the other hand, compares the value of a counter 14 which counts the number of circuits in a hooking state with the value of a register 13 wherein the permissible number of incoming circuits is recorded when there is a new incoming call, and the counter 14 counts up by one by accepting the new incoming call when the value of the counter 14 is smaller, namely, when the number of circuits in the hooking state is smaller than the permissible number of incoming circuits. When the values of the counter 14 and register 13 are equal to each other, the new incoming call is not accepted and the number of circuits connected to the audio response unit is secured for automatic origination from the audio response unit 12.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a system for restricting incoming calls to a voice response device by receiving an instruction from a host computer about the number of lines allowed for incoming calls in a voice response device.

[Background of the invention]

The current method of restricting incoming calls in voice response devices is that the host computer instructs the voice response device to restrict incoming calls in response to the incoming lines, thereby restricting incoming calls to the voice response device in response to lines.

In other words, as shown in Figure 1, the number of lines allowed for incoming calls is 12.
Taking a voice response device with 8 lines as an example, the incoming call priority order 4 from the subscriber telephone 3 to the voice response device 1 is 0.16j2, 48, 6 of the connection line number 2 of the voice response device 1'YI).
4,80,96,112.1,17°35,...
When the voice response device connection line with the lowest rank becomes vacant, the call arrives on that voice response device connection line again.

Therefore, after managing the priority order of incoming calls to the voice response device and the correspondence between the voice response device's tangential line, instructions for restricting incoming calls from the host computer are made in correspondence with the voice response device's internal tangential line.

(For example, the host computer has a conversion table for the incoming call priority to the voice response equipment and the voice response equipment connection line.) However, due to a failure in the subscriber line, it is necessary to switch between the subscriber line and the voice response equipment tangential line. If you do so, or if you update the incoming call priority to the voice response device and the response of the voice response device connection line due to the addition of subscriber lines, not only will this have the disadvantage that it will affect the program of the host computer. As a voice response device, the conventional voice response device j! In the incoming call restriction instruction method that supports the connected line,
This method has the disadvantage that it is necessary to constantly check whether or not there are incoming calls on all connected lines.

[Purpose of the invention]

It is an object of the present invention to eliminate the drawbacks of the above-mentioned prior art and to provide a system in which the voice response device controls the number of calls received by the voice response device by receiving an instruction from the host computer about the number of lines that are allowed to receive calls. There is K.

[Summary of the Invention] The present invention provides a restriction on incoming calls to a voice response device in order to allow both incoming calls to the voice response device and automatic outgoing calls from the voice response device to the user to coexist on a limited voice response device connection line. , the voice response device is controlled by an instruction from the host computer regarding the number of lines allowed for incoming calls.

[Embodiments of the invention]

Hereinafter, embodiments of the present invention will be described based on FIG. 2. FIG. 2 is a block diagram of a host computer and voice response system according to the present invention.

Here, 11 is a host computer, 12 is a voice response device, 13 is a register for storing the number of incoming lines instructed by the host computer, 14 is a counter for counting the number of lines currently in progress, and 15 is a counter for counting the number of lines currently in progress. The subscriber telephone 16 in process is a subscriber telephone subject to incoming call restriction.

The voice response bag ft12 has now been instructed by the host computer 11 to set up a call restriction line to the voice response device.
The value is stored in the register 13. On the other hand, when there is a new incoming call, the voice response device 12 checks the values of the counter 14 (initial value is zero) that counts the number of lines in progress and the register 16 that records the number of lines that are allowed to receive calls. After comparison, if the value of the counter 14 is smaller, that is, if the number of lines in progress is less than the number of allowed incoming calls, the new incoming call is accepted and the counter 14 is incremented by one. However, when the values of the counter 14 and the register 15 are equal, the new incoming call is not accepted.
Secure a voice response device connection line for automatic calls from the voice response bag [12].

Note that the counter 14 counts the number of lines currently in progress, so when one call in progress is completed, the value of the counter is decremented by one.

〔Effect of the invention〕

According to this embodiment, the host computer does not need to manage the correspondence between the telephone corporation standard incoming call priority and the voice response device connection line, and only manages the number of pending calls as a voice response device. It has the effect of being regulated.

Claims (1)

[Claims] In a voice response system comprising a host computer and a voice response device, the number of lines allowed to receive calls to the voice response device is recorded in a recording means in the voice response device based on an instruction from the host computer; The voice response device is provided with a counting means for counting the number of lines currently in progress, and when a new call to the voice response device is received, the count value of the counting means indicating the number of lines in progress and the incoming call are An incoming call restriction method for a voice response device, characterized in that the recorded value of the recording means indicating the number of permissible lines is compared, and if the respective values are equal, incoming call restriction is applied to the call.
