Abstract

PURPOSE:To allow a transfer registration party to call back a call during transfer by a release procedure by connecting a caller line during transfer to a release request telephone set when the registration of absence transfer is released. CONSTITUTION:A transfer destination is stored and registered in advance for each telephone set 1 to be accommodated to an absence transfer memory 4 and when an incoming call comes to a telephone set 1A to which absence transfer is registered, the call is connected to a registered transfer destination 1B. When an incoming call comes to the telephone set 1A whose transfer destination 1B is registered in the absence transfer memory 4, the caller line of the incoming call is recorded as an incoming call line 20 and the transfer connection state of the incoming call is recorded. When the release request of the absence transfer registration is received from the telephone set 1A whose transfer destination is registered and when a call comes during absence transfer and the transfer destination is not replied, the transfer procedure on progress is interrupted and the incoming call line 20 is connected to the telephone set 1A whose absence transfer registration is released.

があった。As described above, in the conventional call forwarding system, when a request for canceling the registration of the call forwarding is made, the exchange simply cancels the registration, and the incoming call immediately before the cancellation is received. Is configured to retrieve the transfer destination from the absence transfer memory and continue the transfer procedure until completion, so the incoming call is registered until the registrant leaves the transfer destination and returns to the registered phone to cancel the registration. Connected to the transfer destination that was in the middle,
There has been a problem that the caller has no choice but to make a call again after a long unresponsiveness in an unmanned place such as a conference room.

接続する。In one of the call forwarding systems according to the present invention, the call forwarding destination for each telephone accommodated in the call forwarding memory is registered in advance, and a call is received to the call forwarding telephone. At this time, in the call forwarding method of the switch that connects this call to the registered transfer destination, when the switch receives an incoming call at the telephone set whose transfer destination is registered in the call forwarding memory, the caller side line of this incoming call is called. While recording as a line,
The transfer connection status of this incoming call is recorded, and when a call from the telephone set which has registered the transfer destination is detected and a request for cancellation of the call forwarding registration is received, there is a call being forwarded and the transfer destination is not responding. When the connection status is reached, the transfer procedure in progress is stopped / interrupted to cancel the registration of the call forwarding and the called line is connected to the called telephone (the telephone requesting the cancellation of the call forwarding registration).

る。First, when the call control device 3 detects a call from the telephone set 1A (101), it sends a dial tone (102) upon completion of dial reception preparation, and issues a call forwarding cancellation request with a special dial code, for example. The number is received (103). Next, the call control device 3 searches the call forwarding telephone 1A in the call forwarding memory 4 to investigate the connection status (104), and also indexes the call receiving line from the call forwarding memory 4 (105).

In the case of an incoming call from an outside line such as 0 (106), the call control device 3 transfers the call if the connection status is dialed (107) but not answered (108), and if dialed in step 107 before dialing. Is suspended and suspended (109), and if there is a connection, it is restored and the registration of the call forwarding is canceled (110).

After step 110, the call control device 3 detects (111) the on-hook state of the calling party requesting the release of the call forwarding and the telephone 1A, and then sends a call signal to terminate the transfer procedure. It becomes a call (112), and a regular call procedure is set. In step 106, if the call is received from an outside line and the transfer destination dial number is not transmitted, the process is connected to step 109.

Is connected to the transfer call path formed by connecting the call incoming line and the transfer destination so that only the receiving path can be intercepted by the calling telephone set 1A and an interrupt sound is inserted (120) into the calling path. Perform the interrupt procedure. Next, when the predetermined special number for interruption is received from the calling telephone set 1A (121), the call control device 3 connects the calling telephone set 1A to the transfer communication path to enable the three-way call (122). Then, the absence transfer registration is canceled (123), and the procedure ends. Normally, the transfer destination telephone goes into an on-hook state by a three-way call and the call path is disconnected.

Illustrates the procedure for calling after unregistered call forwarding
As described above, after the transfer procedure is interrupted and restored in step 109, the called line may be connected to the call forwarding cancellation requesting telephone of the called telephone to respond without calling and the call forwarding registration may be canceled. However, the present invention is not limited to the above description. Further, as the interrupt operation of steps 120 to 123, one that can be performed by a known method can be applied. Although the operation procedure is shown and described in FIG. 1, it is sufficient that the function is not impaired even if there is a sequence before and after. Although the above embodiment has been described as one procedure, the procedure before and after the response is independent.

きるという効果が得られる。As described above, according to the call forwarding system of the present invention, the forwarding procedure is interrupted before the response and the connection procedure with the legitimate called party is executed, and after the response, the three-way call is performed. Because the switch is configured to perform the connection procedure to check, the caller does not have to wait for an indefinite time when moving from the transfer destination and returning, and the transfer registrant does The effect that the call being connected to the transfer destination can be recalled is obtained.
