Abstract

PURPOSE: A method for supplying a response completion tone in other extension is provided to connect an incoming call with a first call receiver when more than two receivers attempt to answer the incoming call and to inform other receivers of a connected result, so as to prevent the other receivers from continuously attempting to answer the call. CONSTITUTION: If every terminal telephone rings in a private exchange, the private exchange identifies which terminal telephone answers an incoming call. If a terminal telephone firstly answers the call, the private exchange connects the incoming call with the terminal telephone and informs the rest terminal telephones of a 'response completion' signal. The rest terminal telephones deliver specifically-typed signals during regular time, to inform users of the 'response completion'.

Description

Method of generating answer tone that other extension answered already in private exchange}

The present invention relates to a private exchange, in particular, when a call received through a trunk line at a private exchange rings a ring at various stations, when one station first responds, it sounds an acknowledgment signal indicating that the other station has answered as an unanswered station. In addition, the present invention relates to a method for providing a response completion tone at another station with respect to an incoming call at a private exchange.

In a private exchange such as a PABX (Private Automatic Branch Exchange), when a call is made through a trunk line, a ring is ringed at various stations at the same time. When the user calls through any one extension, the call is received at the first station which has been answered among the various ring rings, and the ring stops.

However, if more than one extension user attempts to answer when the ring rings, the call is connected to the extension that answered at least a little, and the user who is ringing to the other extension hears the same dial tone as the outgoing attempt.

That is, in the private exchange according to the prior art that operates as described above, when a ring is ringed according to incoming calls at various stations at the same time, the other station does not perform any operation even if the user rings at any one station, the other station There was a problem that the user of could be unnecessarily attempted to receive.

Therefore, an object of the present invention, which was devised to solve the problems of the prior art operating as described above, when rings ring simultaneously in several stations, responding at any one station generates a short response completion tone to the remaining stations. It is to provide a method of providing a response tone in the other station to the incoming call in the private exchange, which indicates that the station has responded to the incoming call.

An embodiment of the method for providing a response completion tone at another station for an incoming call in a private exchange according to the present invention, which is designed to achieve the above object, is controlled and designated by one private exchange and the private exchange. A plurality of terminal telephones using a trunk line, each having a unique extension, comprising: ringing the plurality of terminal telephones by an incoming call generated by the trunk line (s100); Checking, by the private exchange, which one of the terminal telephones has answered (s200); If any one of the terminal telephones responds first, connecting the incoming terminal telephone and the incoming call by the private exchange (s300); After the answering terminal telephone is connected to the incoming call, the private exchange sending a "answer complete" signal to all other terminal telephones except the answering telephone (s400); And transmitting, by the terminal telephones receiving the "answer complete" signal, a special type of signal for a predetermined time to inform the user that the response to the incoming call is completed in the other terminal telephone (s500).

Hereinafter, with reference to the accompanying drawings will be described in detail the operating principle of the preferred embodiment of the present invention.

1 is a block diagram showing an embodiment of a private switching system configuration applied to the present invention, as shown, a switch 200 connected to a public switched telephone network (PSTN) and performing a switching function. )Wow; It is composed of a plurality of terminal phones (310, 320), the terminal phones (310, 320) is composed of a keyset (keyset) having both voice and data communication paths, not a general telephone having only a voice communication path.

In order to provide a telephone function to a user as described above, in a private exchange where a small number of wires are used together by a large number of users, a group of users having the same characteristics may be grouped into one group to designate a trunk line used by this group. do.

In general, a ring is ringed simultaneously to a plurality of extension users in a group, and the private exchange 200 makes a call with an extension that is answered first among the various extensions in which the ring rings.

The function of the present invention is that if a call is answered by one of several stations ringing the ring line, the ring is ringed directly to another station where the ring is ringing through a special tone or music or liquid crystal display (LCD) indicator. By notifying that the extension is completed, unnecessary effort to try another extension response can be prevented.

In order to indicate that the other station has completed the response, it is possible only in the keyset, not the general telephone. The exchange 200 makes a data message “response complete” as soon as the response of the terminal telephone 310 is confirmed and the ring rings. When the call is sent to the other root extension telephone 320, the received terminal telephone (KEYSET) 320 can immediately notify the user of the completion of the response at the other station through the ring signal and other prepared tone, music or LCD display. have.

2 is a flowchart illustrating an embodiment of a method for providing a response complete tone according to the present invention. The operation and effects thereof will be described in detail below.

If the ring is ringed to all terminal telephones which are controlled by one private exchange in step S100 and belong to one group, in step S200 the private exchange checks which terminal telephone among the terminal telephones has answered.

If either terminal telephone has answered first, the private exchange connects the call with the answered terminal telephone in step s300, and signals all the terminal telephones except for the answered telephone in step s400 to the "answer complete" signal. Send it.

The terminal phones receiving the "answer complete" signal in step s500 sends out a special type of signal for a certain time period to inform the user that the response to the incoming call is completed in the other terminal phone.

In the present invention operating as described in detail above, the effects obtained by the representative ones of the disclosed inventions will be briefly described as follows.

According to the present invention, when several users call for more than one CO line, several people try to answer the incoming call, so that only one extension becomes a call and the rest prevents unnecessary trouble of listening to an unwanted dial to increase work efficiency. , Intelligent K / P function. In addition, the present invention, in the case of a domestic office where several people use several trunk lines together, when two or more people attempt to answer a call received on the trunk line, only the person who attempted the call is connected to the other person and the remaining answer attempter By informing them, it prevents the rest of the response attempters from continuing to try to respond.
