A real-time call monitoring method based on network packet capture analysis

Abstract

The invention provides a real-time call monitoring method based on network packet capture analysis, the method includes: the first step: capture the network packet of the telephone system in real time; the second step: analyze the network packet of the telephone system; the third step: obtain the uplink / downlink voice Stream; Step 4: Decode the voice stream of the telephone system; Step 5: Encode the decoded voice data; Step 6: Encapsulate the target voice code according to the media player protocol; Step 7: Play the voice stream And push the voice stream to the target playback device. The present invention combines the port mirroring technology with the streaming media service technology to solve the technical requirements of supervisors to monitor the real-time call voice stream after the telephone system is connected to the real-time analysis system, so that the supervisors can combine the real-time analysis results at the same time The real-time call voice stream provides objective data support for the verification needs of real-time analysis results.

Description

technical field [0001] The invention belongs to the technical field of communication monitoring, and in particular relates to a real-time communication monitoring method based on network packet capture analysis. Background technique [0002] Provide a certain telephone monitoring capability for the telephone system, connect the real-time analysis system for the telephone system, and supervisors can monitor the real-time call voice stream. In the prior art, the monitoring communication within the telephone system itself involves the exchange of telephone signaling. The connection between the monitoring line and the monitored line is completed through signaling exchange, which requires additional communication by the telephone system and involves the control of monitoring authority. etc., the customer needs to upgrade the version or make a second purchase, which will bring additional purchase costs. [0003] And there are following deficiencies in the prior art: [0004] 1) ...

AI Technical Summary

Problems solved by technology

[0004] 1) The existing technology involves interaction with the telephone system, causing interference to the telephone system, and the risk of launching the monitoring function is high;

[0005] 2) The monitoring function of the existing technology requires the customer to upgrade the telephone system, upgrade the version or make secondary purchases, and the transformation cost is relatively high;

[0006] 3) Existing technology needs to transform PBX / CTI, and a large number of open source telephone systems cannot be applied
