Field of the Invention The present invention relates to a voice monitoring system and method, and more particularly to a voice monitoring system and method for network telephone. [Prior Art] Voice over Internet Protocol (VOIP) is a technology for transmitting voice based on the Internet Protocol (IP). In the Internet telephony system, the voice is RTP (Reaitime Transp〇rt Φ). Protoco Bud Transfer Protocol) The form of the packet is transmitted over the network. The voice monitoring function is a mandatory requirement of the national security department for various communication means. With the development of the VoIP service, users and administrators of the VoIP phone encounter security department requirements for monitoring and recording of specific user calls. However, in the prior art, there is no device and method for monitoring the voice information in the network phone, and therefore, the voice in the network phone cannot be effectively monitored. ❹ 【Contents】 In the above valley, it is necessary to provide a voice monitoring system and method capable of monitoring the voice of the Internet phone. The network telephone voice monitoring system comprises a soft switching device storing a monitoring target horse, a monitoring server and a monitoring terminal, the road power, the voice monitoring system and a first network telephone terminal and the first The VoIP terminal is connected through the Internet, and the first VoIP phone, the ς terminal and the second VoIP terminal can communicate through the Internet, and the softswitch device judges the words.

Compared with the prior art, the voice telephone monitoring system and the method of the invention can effectively monitor, record and save the voice information of a specific user required by the security department, and the system architecture and the monitoring method are simple. [Embodiment] Referring to FIG. 1, a preferred manner of the network telephone voice monitoring system i of the present invention is used to perform a call to a specific user required by a security department, including a soft parent changing device 10, and a soft switching device. The network is connected to the monitoring server 30 and the monitoring terminal 50 connected to the monitoring device 200952392. The softswitch device 10 is connected to a security device 20 set by a security department. The voice monitoring system 1 is respectively associated with A first network telephone terminal 40 and a second network telephone terminal 60 are connected by an internet, and the first network telephone terminal 40 can communicate with the second network telephone terminal 60 via the Internet. The security device 20 stores a monitoring target number, that is, a phone number of a specific user that the security department requires to listen to; the first network phone terminal 40 and the second network phone terminal 60 each include at least one network that can be used for the network. a telephone terminal in the telephone; the softswitch device 10 is a device that implements a call control function by software, and can receive the call transmitted by the first network telephone terminal 40 and the second network telephone terminal 60 via the Internet. And signaling, and determining whether the monitoring target number is transmitted by the security device 20, the call signaling includes a phone number, a transmission path, and the like of the first network telephone terminal 40 and the second network telephone terminal 60, and the softswitch device The phone number of the first network telephone terminal 40 and the second network telephone terminal 60 needs to be compared with the monitoring target number. If it exists in the monitoring target number, the call signaling is modified to make the first network telephone terminal. The voice data packet of the 40 and the second network telephone terminal 60 is transmitted by the monitoring server 30; the monitoring server 30 is provided with a control device having a voice codec function. 31. The control device has a data interface 313 for transmitting voice information, and the monitoring server 30 is connected to the softswitch device 10 by using an internetwork, and the monitoring server 30 can control the voice data packet by using the control. The device 31 performs codec conversion, converts the voice data packet into PCM (Pulse Code Modulation) voice, and transmits the converted voice to the monitoring terminal 50 through the data interface 313; the monitoring terminal 50 is used for Receiving the monitored voice transmitted by the data interface 313 of the monitoring server 3; the monitoring server 30 can simultaneously transmit the voice data packet to the first network telephone terminal 40 and the second network through the Internet. The telephone terminal 60 does not affect the call between the first network telephone terminal 40 and the second network telephone terminal 60. In the present embodiment, the VoIP protocol uses Slp^The Session Initiation Protocol (Session Initial Protocol). Ο

The telephone number of the terminal 60 = the same information 'The softswitch woven 1G judges that the terminal is like _ signaling is (four) = = both sides belong to the monitoring target _ Μ service code, then modify the call signaling, and to the supervisor 30 shipping monitors the second network telephone terminal 1 life: so that the first network telephone terminal 40 is connected to the first network terminal, and the first communication terminal is configured to establish a call connection by the monitoring server 3 to enter the telephone terminal 6G. The voice data package is subscribed and transmitted, and the monitoring and feeding device M Yishan system 31 transmits the voice service 30 to the data interface (10) of the control device, and transmits it to the monitor through the control terminal 5〇. End the I, record and save the voice information, such as 200952392 If only one of the telephone numbers belongs to the monitoring target number, the monitoring server 30 only needs to convert the voice data packet of one of the parties to be monitored into the voice information of the analog signal by the control device 31, and then transmits the voice information to the monitoring terminal 50 through the data interface 313. If the call signaling does not belong to the interception target number, the softswitch device 10 directly establishes a call between the first network telephone terminal 40 and the second network telephone terminal 60. Referring to FIG. 2, the flow of the voice telephone voice monitoring method of the present invention includes the following steps: Step 1: The security device 20 transmits the monitoring target number to the soft switching device 10. The second step: the first network telephone terminal 40 calls the second network telephone terminal 60 via the Internet. The third step: the first network telephone terminal 40 transmits the call signaling to the softswitch device 10 via the internet. The fourth step: the softswitch device 10 determines whether the call signaling transmitted by the first network telephone terminal® 40 belongs to the interception target number, and if it is the interception target number, modifies the call signaling and sends a monitor command to the interception server 30. The voice channel between the first call terminal 40 and the second call terminal 60 is established by the monitoring server 30, and proceeds to the next step; if not, the first network telephone terminal 40 and the second network are directly established. The call between the telephone terminals 60. The fifth step: the listening server 30 converts the voice data packet transmitted by the first network telephone terminal 40 and the second network telephone terminal 60 into PCM voice by the control device 11 200952392 31, and transmits the voice data packet to the PCM voice through the data interface 313. To the monitoring terminal 50. Step 6: The listening terminal 50 monitors the voice, and records and saves the monitored voice, and the monitoring is completed. In addition, the voice monitoring system 1 can implement the functions of voice prompting and conference call by setting the softswitch device 10 to cause the softswitch device 10 to transmit different request commands to the listening server 30. The VoIP voice monitoring system 1 and method of the present invention can effectively monitor, record and save voice information of a specific user required by the security department. In summary, the present invention is in accordance with the conditions of the invention patent application, and the patent application is filed according to the law.
