In conjunction with advanced Digital Signal Processing, ip voice technology and mass-memory unit, under the IP network environment of complexity, provide online recording simultaneously multiplex telephony to be recorded, the IP recording scheme of offline backup can be good at solving the application needs of business unit.

Summary of the invention

Purpose of the present invention realizes the doubling recording scheme under a kind of IP network, the convenient a kind of IP recording scheme implemented under a plurality of network environments that solves.

In order to realize goal of the invention, the technical scheme of employing is as follows:

Under the IP network environment of operator, by the gentle words machine that SBC connects public network, realize that VOIP calls out, as shown in Figure 2.SBC can connect the network that a plurality of local area network (LAN)s are acted on behalf of up by public network, and SBC can restrain the speech channel of gentle words machine all and converge on the network interface card.

The network interface card of another network segment of SBC, through Ai-Logic high resistant terminal box such as Fig. 1, be connected to the IP network switch of operator, this Ai-Logic high resistant terminal box can not influence the existing network quality, even terminal box outage, do not influence existing network service, this terminal box does not need to do the setting of complicated port mirror image, and the data that directly just will advance terminal box copy two parts of identical data from the port output of Monitro.

The network interface card of the machine at our application program recordnode place connects the Monitro port of Ai-Logic high resistant terminal box, should be with program according to configuration, realize various functions, application program recordnode has three kinds of operational modes, first kind is the real-time recording pattern, according to the data flow that receives, analyze sip message, take out the RTP port of both sides' conversation according to SDP, according to the port of RTP bag the rtp streaming of caller being preserved into respectively with called rtp streaming does not have the suffix file, behind the end of calling, the file of preserving is preserved into the file that suffix finishes, through the RTP crossover tool that we research and develop ourselves, automatic scan will have the RTP file conversion of suffix to become mp3 file or wav file, provide the user to use; Second kind is the data flow that will receive, and analyzes the type of packet, and sip message is preserved into the .cap file with RTP message, according to the size of data volume, produces different files automatically, conveniently investigates the recording of problem and off-line afterwards and uses; The third is the off-line recording, application program launching does not read information from network interface card, but reads information from cap file the inside, SDP by the SIP signaling, find the RTP port of calling, again according to the RTP bag, preserve the RTP file of calling and called respectively, behind the end of calling, by the RTP crossover tool, convert two-way RTP to mp3 file or wav file again, provide the user to use.

The invention provides a kind of implementation of IP based network doubling recording, under a plurality of local area network (LAN)s and wide area network and the situation of depositing, carrying out the speech channel convergence by SBC converges, give application program recordnode by Ai-Logic high resistant terminal box with the speech channel of converging, because Ai-Logic high resistant terminal box does not need the port duplicate instructions that copies, the identical data flow of two-way that copies that can be safe and reliable is given application program, thereby the recordnode application program realizes online IP recording and off-line IP recording simultaneously.

Therefore, the invention provides the implementation that a kind of IP based network doubling is recorded, following characteristics are arranged.

(1) solve a plurality of local area network (LAN)s and wide area network and the network environment of depositing under, the problem that the speech channel convergence is converged

The present invention solves under the network environment of a plurality of local area network (LAN)s and wide area network doubling, the conversation of software terminal is all restrained converging to one and throw the net to come above the card by SBC.

(2) realize the recording of online recording and off-line simultaneously

The present invention is using Ai-Logic high resistant terminal box, do not need complicated port mapping instruction, safely and efficiently will be through the data of high resistant terminal box netting twine, copying two parts of identical data exports from the Monitor port, move two recordnode programs, be arranged to real-time recording for one, another is arranged to preserve the initial data stream mode, the file of preserving original data stream is descending in the situation of follow-up needs, can carry out the off-line recording.
