[0011] 1. This patent document mainly adopts the traditional SIP protocol-based IP call voice recording technology, that is, the SIP protocol interaction and media voice reception are on the same physical server, so that the voice recording of SIP calls can be realized, but a single SIP receiving server can only Voice recording is performed according to the performance of its own server, which greatly reduces the receiving ability of the SIP receiving server

Abstract

The invention provides a distributed IP recording method and system based on the SIP protocol, including a central management module, a protocol interaction service module, and a voice recording entity service module. The present invention uses the characteristics of the SIP protocol to modify the media description parameter SDP to realize the distribution of media streams, and through the distributed architecture, the present invention realizes the division of control messages and media streams, centrally receives control messages, and distributes received voice data, thereby achieving Stackable, scalable deployment of recording capabilities.

Description

technical field [0001] The invention relates to the technical field of VOIP voice communication, mainly including SIP control protocol and RTP voice stream synthesis technology, and specifically relates to a distributed IP recording system and method based on the SIP protocol. Background technique [0002] The traditional IP phone recording method SPAN is to back up the network data through the port mirroring technology of the switch. The recording server captures the network data, analyzes the SIP protocol and RTP voice stream data, and synthesizes and saves the voice data. This method depends on the physical location of the IP phone. For IP phones across switches and routers, port mirroring is quite cumbersome to implement. [0003] Most of the traditional VOIP voice calls use the SIP protocol for call control. On this basis, the Cisco phone system proposes the BIB (Build In Bridge) recording function. The IP phone can call a third-party terminal through the SIP protocol w...
