VoIP recording system and recording method

Abstract

The invention discloses a VoIP (Voice over Internet Protocol) recording system and a recording method. The VoIP recording system comprises a recording server, a voice server, a switch, a voice gateway and a plurality of IP (Internet Protocol) phones, wherein the voice server is used for storing registration status information of all the IP phones in the system and the IP address of the recording server; the recording server is used for storing the telephone number of an IP phone requiring recording in the system and the required recording manner, subscribes the registration status information of the IP phone requiring recording to the voice server, and sends a recording subscription request message to the corresponding IP phone according to the IP address; the IP phone sends a recording annunciation response message to the recording server according to the received recording subscription request message; and the recording server records the IP phone in a silent monitoring manner according to the recording annunciation response message. By adopting the system and the method which are provided by the invention, recording of the VoIP system can be achieved according to message passing, and the recording networking scheme is more flexible and convenient.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a voice over Internet Protocol (Voice over Internet Protocol, VoIP) recording system and recording method. Background technique [0002] The recording of the VoIP system is divided into two types: the recording between the internal line and the internal line, and the recording between the internal line and the external line. At present, these two recordings are mainly realized through three networking schemes: local port mirroring recording networking, port-based analyzer (SPAN) recording networking and port-based remote analyzer (RSPAN) recording networking, as follows The three recording networking solutions are briefly introduced respectively. [0003] figure 1 It is a schematic structural diagram of a local port mirroring recording network in the prior art. like figure 1 As shown, the structure mainly includes a recording server 101, a voice server 102, a switch 10...

AI Technical Summary

Problems solved by technology

[0012] When recording, the switch 303 needs to mirror all data packets to the recording server, which requires the switch to support the mirroring function of the data packets, and when there are too many voice gateways 304, the performance of the switch 303 will be greatly affected

[0013] From the above analysis, it can be seen that the three networking sch
