JPH04319850A - Incoming connection system for automatic telephone exchange - Google Patents

Abstract

PURPOSE:To freely select the answer or transfer of each incoming call at a subscriber terminal of the incoming side. CONSTITUTION:In a connection processing state for incoming calls of an automatic telephone switchboard, a fact whether the automatic incoming transfer is set or not to the selected subscriber terminal of the incoming side by reference to a main storage of the switchboard (step 2). If not, the subscriber terminal is called (step 3) for check whether a transfer request signal showing the request of the incoming transfer is transmitted or not before the answer of the subscriber terminal (step 4). When the transfer request signal is received, the memory showing the valid/invalid states of transfer of the main storage of the switchboard is set in a valid state. Then the connection is switched to the incoming transfer destination that is previously registered (step 5).

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call connection system for automatic telephone exchanges.

0002

2. Description of the Related Art Conventionally, in the incoming call connection system of an automatic telephone exchange, the called subscriber is required to answer the incoming call, or in the case of an incoming call to a subscriber for whom full automatic forwarding has been set in advance,
Either the incoming call is immediately transferred to the set subscriber, and the receiving subscriber cannot freely select whether to answer or transfer the incoming call.

0003

[Problems to be Solved by the Invention] In this conventional incoming call connection system, it is necessary for the subscriber on the receiving side to set in advance whether the incoming call should be answered or forwarded in a fixed manner on the telephone. It was not possible to freely choose to answer or forward each incoming call. For this reason, for example, subscribers who often leave their desks to work elsewhere may have to register or cancel their transfer registration each time they do so. This may cause inconvenience if the incoming call cannot be transferred to.

SUMMARY OF THE INVENTION An object of the present invention is to provide an incoming call connection system for an automatic telephone exchange that allows a subscriber terminal on the called side to freely select whether to answer or transfer each incoming call.

[0005]

[Means for Solving the Problems] In the incoming call connection method of the automatic telephone exchange of the present invention, in the incoming call connection method of the automatic telephone exchange, when the automatic telephone exchange performs connection processing of an incoming call, the selected called party subscriber terminal If it is determined that automatic call forwarding is not set for the called subscriber terminal, the called subscriber terminal is called, and before the called subscriber responds, the called subscriber terminal issues a transfer request indicating that it wishes to forward the call. When a signal is received, the incoming call is transferred to a pre-registered call transfer destination.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings. FIG. 1 is a flowchart showing the process flow of an incoming call connection method in an automatic telephone exchange according to an embodiment of the present invention. Initially, the exchange receives the called party subscriber number dialed by the calling party (step 1). Next, the exchanger
Referring to the main memory (not shown), it is checked whether full automatic call forwarding is set for the selected subscriber terminal, which is a multi-function telephone, for example (step 2).
). If full automatic call forwarding is set, the forwarding destination registered in advance is read from the main memory (not shown) and the call forwarding process is immediately performed (step 5). If it is determined that this fully automatic call forwarding setting is not set, for example, if the display in the memory is "0", a ringing signal will be sent to this subscriber terminal and an indicator lamp will be turned on to indicate that the call is being received. Make it blink (step 3).

Next, before the subscriber terminal responds, it is checked whether a transfer request signal indicating that the subscriber terminal desires call transfer is transmitted (step 4). Then, this transfer request signal (for example, one of the multi-function telephones)
Assign one function button)
The display on the memory is set to "1", that is, "valid", and the process of step 5 is performed. Then, when the process is completed, the corresponding memory is returned to "0". On the other hand, it is checked whether a response signal has been sent from the subscriber terminal side (step 6), and if a response signal is received, normal incoming call connection processing is performed (step 7). In this way, the subscriber terminal on the receiving side can select either response or call transfer for each incoming call.

[0008]

Effects of the Invention As explained above, in the present invention, when the exchange recognizes a transfer request signal transmitted from the terminal of the called subscriber before the called party responds, the transfer request signal registered in the main memory is Since the destination number is extracted and the incoming call is forwarded, the called subscriber or the operator at the relay stand can, for example, check the caller number of the incoming call and set it in advance without answering. It becomes possible to transfer to a forwarding destination, etc.
This has the effect that call processing can be performed quickly.

Claims (1)

[Claims] Claim 1: In an incoming call connection method of an automatic telephone exchange, when it is determined that automatic call forwarding is not set for a selected called subscriber terminal when the automatic telephone exchange processes an incoming call, When calling the called subscriber terminal and receiving a transfer request signal from the called subscriber terminal indicating that the called subscriber wishes to transfer the call before the called subscriber responds, the incoming call is transferred to a previously registered incoming call. An automatic telephone exchange incoming call connection method characterized by switching the connection to the forwarding destination.
