Hereinafter, a call recording method between an original caller and a rerouting called party according to an embodiment of the present invention will be described with reference to FIGS. 3 to 5. Call recording method between the original caller and the rerouting recipient according to an embodiment of the present invention is made by connecting a three-person call through the IVR server, and intercepts it.

First, a call connection process between the caller phone 100 and the first phone 810 will be described with reference to FIG. 3. 3 is a signal flow diagram illustrating a call connection process between the caller phone 100 and the first phone 810.

First, the first caller attempts to call the representative number using the caller phone 100 (S110). The trunk line switch 200 receiving the call through the representative number inquires the actual destination number of the representative number received by the service control system (SCP) of the intelligent network 300 (S120).

Next, the service control system (SCP) of the intelligent network 300 notifies the trunk line switch 200 to the actual called number of the representative number (S130). The trunk line exchanger 200 notified of the called number performs a call connection to the PBX 500 (S140). The PBX 500 in which the call connection is performed with the trunk line switch 200 connects the call to the first telephone 810 (S150).

Through the above process, the call between the caller telephone 100 and the first telephone 810 is connected (S160), and a telephone call is performed between the first caller and the first agent using the first telephone 810. .

Hereinafter, a call recording method between an original caller and a rerouting called party according to an embodiment of the present invention will be described with reference to FIG. 4. 4 is a signal flowchart illustrating a call recording method between an original caller and a rerouting called party according to an embodiment of the present invention.

Through the process shown in FIG. 3, a call between the caller phone 100 and the first phone 810 is connected, and the first caller and the first agent are talking to the second agent. There may be cases where a call needs to be diverted. At this time, the first counselor requests the CTI server 400 to transfer the call to the second counselor and record the call using the first terminal 820. More specifically, the first terminal 820 requests the CTI server 400 for the call transfer and recording of the call to the second telephone 910 for three persons (S210).

Next, the CTI server 400, which has received a three-way call for call transfer and recording from the first terminal 820, is a service control system (SCP) of the intelligent network 300. A called number and an IVR number which is a called number of the IVR server 600 are provided (S220).

Next, the service control system (SCP) of the intelligent network 300 provided with the second called number and the IVR number notifies the trunk line switch 200 of the second called number and the IVR number (S230). The trunk line switch 200 notified of the second called number and the IVR number performs a call connection (rerouting) to the second telephone 910 through the second called number (S240), and the IVR server 600 through the IVR number. Call connection is performed at (S250).

Due to the above steps, the three-person call between the caller phone 100, the second phone 910 and the IVR server 600 is connected (S260). At this time, the first caller who is using the caller phone 100 may not recognize that a 3 person call including the IVR server 600 is being connected. Therefore, the IVR server 600 is connected in the form of listening to the call between the caller phone 100 and the second phone 910.

When a three-person call is connected between the caller phone 100, the second phone 910, and the IVR server 600, the CTI server 400 requests recording from the recording server 700 (S310). The recording server 700 receiving the recording request receives and intercepts the call data of 3 from the IVR server 600 (S320). At this time, the call data between the caller phone 100, the second phone 910, and the IVR server 600 is substantially the caller phone 100 and the second call because the IVR server 600 does not respond at all. It becomes call data between the telephones 910.

Next, the recording server 700 is a three-way call data between the caller phone 100, the second phone 910 and the IVR server 600, that is, substantially between the caller phone 100 and the second phone 910 Record and store the two-person call data (S330).

As described above, the call is transferred from the call between the caller phone 100 and the first phone 810 to the call between the caller phone 100 and the second phone 910 by a call transfer and recording request, and the call is recorded after the call transfer. The server 700 may receive and store the call data between the caller phone 100 and the second phone 910 in the form of tapping.

Hereinafter, a call recording method between an original caller and a rerouting called party according to another embodiment of the present invention will be described with reference to FIG. 5. 5 is a signal flowchart illustrating a call recording method between an original caller and a rerouting called party according to another embodiment of the present invention.

Through the process shown in FIG. 3, a call is transferred between the caller phone 100 and the first phone 810 so that the caller and the first agent call the second phone 910 as needed. When performing the call, the first counselor requests a call transfer to the CTI server 400 using the first terminal 820. The first terminal 820 requests the call transfer to the second telephone 910 to the CTI server 400 (S410).

Next, the CTI server 400 that has received a call transfer request from the first terminal 820 provides a second called number, which is a called number of the second telephone 910, to the service control system (SCP) of the intelligent network 300. (S420).

Next, the service control system (SCP) of the intelligent network 300 provided with the second called number informs the trunk line switch 200 of the second called number (S430). The trunk line exchange 200 notified of the second called number performs a call connection (rerouting) to the second telephone 910 through the second called number (S440).

Through the above steps, the call between the caller phone 100 and the first phone 810 is converted to a call between the caller phone 100 and the second phone 910 (S450).

If a call is connected between the caller phone 100 and the second phone 910 and the first caller and the second agent (rerouting caller) make a call, the second agent determines that the call needs to be recorded. In operation S510, a third person call for recording is requested to the CTI server 400 using the second terminal 920. FIG.

Next, the CTI server 400 receiving the call for recording 3 provides the IVR number which is the called number of the IVR server 600 to the service control system (SCP) of the intelligent network 300 (S520).

Next, the service control system (SCP) of the intelligent network 300 provided with the IVR number notifies the IVR number to the trunk line switch 200 (S530). The trunk line exchanger 200 notified of the IVR number performs a call connection to the IVR server 600 through the IVR number (S540).

Due to the above steps, the three-person call between the caller phone 100, the second phone 910 and the IVR server 600 is connected (S550). As already explained, the first caller using the caller phone 100 may not be aware that a three person call including the IVR server 600 is being connected. Therefore, the IVR server 600 is connected in the form of intercepting the call contents of the caller phone 100 and the second phone 910.

When a three-person call is connected between the caller phone 100, the second phone 910, and the IVR server 600, the CTI server 400 requests recording from the recording server 700 (S610). The recording server 700 receiving the recording request receives and intercepts the call data of 3 from the IVR server 600 (S620). As already explained, the three-way call data between the caller phone 100, the second phone 910 and the IVR server 600 is substantially the same as the caller phone 100 since the IVR server 600 does not answer anything. It becomes call data between the second telephones 910.

Next, the recording server 700 is a three-way call data between the caller phone 100, the second phone 910 and the IVR server 600, that is, substantially between the caller phone 100 and the second phone 910 The two-person call data is recorded and stored (S630).

As described above, the call between the caller's telephone 100 and the first telephone 810 is converted into a call between the caller's telephone 100 and the second telephone 910 by the call transfer request. In response to the recording request of 920, the recording server 700 may receive and store the call data between the caller phone 100 and the second phone 910 in the form of tapping.

As described above, the call recording system and the call recording method between the original caller and the rerouting recipient according to the present invention call the agent inside the call center, that is, the first agent to a contact person outside the call center, that is, the second agent. Even when switching, the call between the first caller and the second agent can be recorded.
