Call monitoring device with function of controlling gating of voice

Abstract

The invention discloses a call monitoring device with a function of controlling gating of voice. The device of the invention is accessed between a telephone channel of an exchange node and a signaling link and comprises a signaling data and telephone channel access module and a voice recognition server. The device also comprises a telephone channel control functional module which comprises a signaling detecting and transmitting unit, a telephone channel crosslink unit, a data and control interface, and a database, wherein the signaling detecting and transmitting unit is used for finishing the transmission and the acquisition of a signaling message; the telephone channel crosslink unit is used for realizing the on / off state of the monitored telephone channel and voice acquisition operation; the data and control interface is used for finishing an acquisition interface of signaling data and a telephone channel control command interface; and the database is used for storing a monitored number. The call monitoring device has the function of controlling the telephone channel, and simultaneously, realizes the discovery and the control of a monitored source, realizes the call monitoring without the change of the conventional network, and avoids the problems of requirement on changing the conventional exchange data, complex use and poor confidentiality and the like in other modes.

Description

technical field [0001] The invention belongs to the field of communication security, and relates to a telephone monitoring device with the function of controlling voice gating in the communication field. The device can realize call monitoring independently of the existing network, and can control the connection and cut-off of the monitored voice channel. Background technique [0002] There are two types of traditional telephone monitoring equipment: [0003] One is to directly connect the monitoring device to the voice channel to collect voice signals. This kind of monitoring lacks flexibility and cannot screen calls according to the calling and called numbers, nor can it realize the control operation of the monitoring call channel. Open and connect calls. [0004] The other is to set data on the telecommunication network and transfer the call to a special monitoring device first. This system can control the dialogue path, and can also set the calling or called number, but ...

Problems solved by technology

[0003] One is to directly connect the monitoring device to the voice channel to collect voice signals. This kind of monitoring lacks flexibility and cannot screen calls according to the calling and called numbers, nor can it realize the control operation of the monitoring call channel. open and receive calls

[0004] The other is to set data on the telecommunication network and transfer the call to a special monitoring device first. This system can control the dialogue path, and can also set the calling or called number, but it also lacks flexibility and requires Configuring data on a specific user number by the telephone office requires the intervention of telecom operation and maintenance personnel, and the operation is cumbersome. At the same time, this monitoring method introduces new switching equipment, so the corresponding tandem office needs to be connected with a special voice channel. The existing network structure needs to be changed, and the call delay will also be increased
