Is transmitted to the recording device 22, and the recording device 22 records the voice call content of each VoIP terminal user.

However, in the second conventional technology as described above, since the traffic including the voice packets of all the VoIP terminals 23 must be processed by the switch device 21 and the recording device 22, in particular, a considerable load is placed on the recording device 22. In order to implement a call recording service, there is a problem in that expensive equipment having superior performance must be used.

In addition, in the second conventional technology, the bandwidth of the local network is narrowed due to traffic transmission and voice packet processing between the switch device 21 and the recording device 22, thereby substantially reducing the bandwidth to be used for the user voice call. There is a problem of poor quality.

In addition, in the second conventional technology, when equipment failure, network failure, etc. occur in the recording device 22, there is a problem in that the reliability of the connection is reduced in connection reliability of all related equipment such as a VoIP terminal and a PC connected to the same local network. .

Therefore, there is an urgent need for a VoIP system such as an IP switch, a switch device, and the like, and a technology capable of implementing a call recording service without using an expensive equipment with superior performance without burdening the network.

In addition, there is an urgent need for a technology capable of efficiently using the limited bandwidth of the VoIP communication network, ensuring connection reliability of communication equipment, and implementing a call recording service without degrading the quality of a voice call service.

In the first embodiment of the present invention, each personal call recording device 30 is separately installed in front of each user-side VoIP terminal 31, and the personal call recording device 30 is connected to the VoIP terminal 31 and the network [ That is, the voice call data (call contents) transmitted / received between the other party's terminal talking to the VoIP terminal user is captured, stored in a file, and transmitted to the remote storage server 34 [Note; 3 shows one VoIP terminal and one personal call recording device. Here, in the present invention, by storing the captured voice call data as a file, the contents of the call are recorded (recorded).

Looking at the connection between the personal call recording device 30 and the VoIP terminal 31, an Ethernet cable (UTP cable) is plugged into a LAN connection port (LAN Port) of the VoIP terminal 31, and the Ethernet cable is connected to the personal call recording device 30. ) To the VoIP terminal connection port, and plugs another Ethernet cable into the LAN connection port of the personal call recording device 30 to an Internet connection device (not shown) such as a modem or an internet router or a hub.

For example, traffic (all data) transmitted and received between the VoIP terminal 31 and the network passes through the personal call recording device 30 through the VoIP terminal connection port, the LAN connection port, and the Ethernet cable. In addition, hereinafter, VoIP terminal connection port and LAN connection port will be collectively referred to as data port for understanding of the present invention.

The personal call recording device 30 may be implemented inexpensively as a Linux-based embedded system using an ARM core, and may include a microprocessor unit (MPU) / digital signal processing processor (DSP) [control unit], a memory (RAM), Storage media such as flash memory or hard disk [data storage], buffers and voice codecs.

Then, the function and operation of the personal call recording device 30 will be described with reference to FIG. 4.

4 is a flowchart illustrating a process of processing voice call data in the personal call recording apparatus of the first embodiment of the present invention. Here, the state in which the user of the VoIP terminal 31 and the other party are talking will be described as an example, and the description thereof will be omitted for the SIP-based call session connection setup process.

When the transmission data outgoing from the VoIP terminal 31 to the network through the data port and the incoming data from the network to the VoIP terminal 31 are input in accordance with the user-to-user call (401), the personal call recording device 30 transmits the data. It is checked whether the received data includes voice call data (402).

If the voice call data is not included as a result of checking whether the voice call data is included, the personal call recording device 30 passes the transmission data through the network and passes the received data through the VoIP terminal. Forwarded to (31) (403).

On the other hand, if voice call data is included as a result of checking whether the voice call data is included, the personal call recording device 30 captures only voice call data (this is referred to as 'sent voice call data') from the corresponding transmission data and receives the corresponding call data. Only the voice call data (called 'incoming voice call data') is captured from the data (404). At this time, it is preferable to capture the voice call data by analyzing and filtering the header part on a packet basis for the data transmitted and received between the VoIP terminal 31 and the network.

Thereafter, the personal call recording apparatus 30 generates the single call content file using the voice codec and the mixing operation while storing the captured transmission voice call data and the received voice call data in a buffer (405). As another example, two files, for example, a file containing only outgoing voice call data ['outgoing call content file'] and a file containing only incoming voice call data [' Incoming call content files'] may be generated respectively.

Thereafter, the personal call recording device 30 stores the generated file in the data storage unit and transmits the generated file to the remote storage server 34 via the network (406). Here, the personal call recording device 30 preferably transmits the file to the storage server 34 after the user-to-user call is completed. In this way, storing the file related to the contents of the call in the personal call recording device 30 is to support the backup function for the file of the storage server 34.

In the present invention, the outgoing voice call data and the incoming voice call data recorded in one file correspond to the contents of a call made between the same user (terminal) in the same time zone, which is the call transmission / reception voice call in the personal call recording device 30. This can be distinguished from the header information of the data.

On the other hand, the content of the call is recorded in the file, the personal call recording device 30 in the present invention, caller information and receiver information such as call time / date, IP address, outgoing telephone number, incoming telephone number, user ID, etc. You can create a file by including it in the file name or in the file.

In addition, the personal call recording device 30 additionally acquires the user's personal information (eg, name, email address, etc.) through linkage with a phone book provided in the VoIP terminal 31 or linkage with a personal address book server (not shown). Can be recorded in a file or as a file name.

In the present invention as described above, in order to express various information about the caller (sender / receiver) in the file or file name where the contents of the call are recorded, the user easily calls his / her call, and the call contents with the corresponding information, Search [eg; By inputting the number that I called as a keyword, it provides a list of files sorted in chronological order, etc.] to conveniently select and listen to the file.

In addition, looking at the advantages of the call recording service implemented by the personal call recording device 30 of the first embodiment of the present invention, it is installed directly in front of the VoIP terminal 31, the user without any influence from the network and external during its operation Can record what you hear and speak.

In addition, the implementation techniques such as the prior arts 1 and 2 generate a load on the circuit as the volume of calls increases (Note; due to the influence of VPN, Back To Back User Agent, etc.), the first embodiment of the present invention is an interference by the network. In addition, it is possible to provide a personalized call recording service by separately setting up a call recording system for each user at a low cost.
