BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0012]
FIG. 1 is a block diagram showing one embodiment of the connection information management / call recording system of the present invention. In the connection information management / call recording system, a call can be made via the IP network 100 between n telephone terminals 3-1 to 3-n, which are IP telephones.
[0013]
The voice call control management device 1 and the logging server 2 are also connected to the IP network 100. The voice call control management device 1 performs a predetermined control required for a telephone call by the telephone terminals 3-1 to 3-n via the IP network 100. Such a control function can be incorporated in the telephone terminals 3-1 to 3-n. In such a case, the voice call control management device 1 becomes unnecessary.
[0014]
The logging server 2 collects connection information and telephone calls from the IP network 100 and stores them in the storage device 2a. In addition, if necessary, the connection information is stored in a connection information database (not shown) constituted by a part of the storage device 2a. Here, the connection information includes caller information such as a caller number, called party information such as a called party number, and date and time information such as a call start / end date and time.
[0015]
FIG. 2 is a block diagram showing a configuration of the logging server 2 shown in FIG. Although not explicitly shown in FIG. 1, the logging server 2 is connected to the IP network 100 via the general-purpose network IF 26, similarly to the voice call control management device 1 and the telephone terminals 3-1 to 3-n. . The network IF 26 absorbs differences in interface characteristics of devices to be connected to the IP network 100 and enables various devices to connect to the IP network 100, and is commonly used.
[0016]
In FIG. 2, the logging server 2 includes a packet collection unit 21, a packet analysis unit 22, a storage unit 23, a registration / search unit 24, and a reproduction unit 25.
[0017]
The packet collecting means 21 collects control signal packets and voice packets transmitted and received in the IP network 100 via the network interface 26. The packet analyzing unit 22 analyzes the control signal packet and the voice packet collected by the packet collecting unit 21 to obtain connection information and call recording data, respectively. The storage means 23 stores the connection information and the call recording data in the storage device 2a. The registration / search unit 24 registers or searches for connection information by communicating with a connection information database (not shown) configured as a part of the storage device 2a. The reproducing means 25 reads the call recording data from the storage device 2a.
[0018]
Next, the operation of the present embodiment will be described with reference to the flowchart of FIG.
[0019]
First, when the logging server 2 is started in the operation continuation state, if the termination has not been completed in the end determination (step S1 in FIG. 3), the process proceeds to a packet collection process (step S2). Collect packets arriving at. Subsequently, the packet analysis unit 22 determines the packet type of the collected packet (Step S3).
[0020]
As a result of the determination, if the packet type is a control signal packet, the packet analysis unit 22 analyzes the control signal packet to obtain connection information, and the storage unit 23 stores the connection information in the storage device 2a. Further, the registration / search means 24 registers the connection information in the connection information database as needed (step S4).
[0021]
In step S3, if the collected packet is a voice packet, the packet analysis unit 22 analyzes the voice packet to obtain connection information, and the storage unit 23 associates the connection information with the call recording data in the storage device. 2a (step S5).
[0022]
In step S3, if the collected packet is a packet other than the control signal packet and the voice packet, the packet is discarded (step S6). Since many packets irrelevant to the call flow in the IP network 100, the logging server 2 excludes them.
[0023]
From step S4, step S5, or step S6, the process returns to the end determination (step S1), and the above-described series of processing is repeated until the end condition is satisfied and the operation ends.
[0024]
With the above operation, the connection information and the call recording data are stored in the storage device 2a in association with each other for the call made by the IP telephone terminals 3-1 to 3-n. It is possible to search for connection information relating to a target call and to reproduce the call recording data by using the reproduction means 25, thereby facilitating maintenance and management of the connection information and the call recording data.
[0025]
Further, since the network interface 26 is a general-purpose device, it is possible to reduce the device cost when connecting the logging server 2 to the IP network 100, and at the same time, to increase the degree of freedom of the installation location of the logging server 2. It is possible.
[0026]
In the above description, both the control signal packet and the voice packet are collected and the connection information and the call recording data are stored. However, only the control signal packet may be collected and the connection information may be stored. . This is because connection information alone is often useful. Further, the control signal packet itself may be stored. In this case, a load is imposed when the control signal packet is reproduced as the connection information, but the storage capacity is smaller than when the connection information is accumulated.
[0027]
Alternatively, only voice packets may be collected and stored in association with connection information and call recording data. Alternatively, if association with connection information is unnecessary, only call recording data may be stored. Good. Further, the voice packet itself may be stored. In this case, a load is imposed when the voice packet is reproduced as the call recording data, but the storage capacity is smaller than when the call recording data is accumulated.
[0028]
In place of the telephone terminals 3-1 to 3-n, a gateway device that converts voice data into an IP packet with another network and transmits / receives the IP packet to / from the IP network 100, a general-purpose personal computer running with IP telephone software, or the like is used. Even so, the present invention can be applied.
[0029]
【The invention's effect】
The first effect of the present invention is that the function of connection information management / call recording is realized by a logging server, so that it can be connected to an arbitrary position on an IP network, and a gateway device to another network such as PSTN can be used. Even for a call that does not pass, connection information management / call recording can be performed.
[0030]
The second effect of the present invention is that a logging server having a function of connection information management / call recording is adopted, so that even in an IP telephone system provided by an arbitrary vendor, a general-purpose interface is sufficient when connecting to an IP network. As a result, the introduction cost can be suppressed.
[0031]
A third effect of the present invention is that a logging server having a function of connection information management / call recording collects control signal packets and voice packets from an IP network irrespective of the operation of devices constituting an IP telephone system. Is to provide a connection information management / call recording system without affecting devices constituting the IP telephone system.
