Technical background

Be accompanied by the flourish of socioeconomic sustainable growth and the communications industry, earth-shaking variation is also taking place in people's life.Telephone communication has become very important contact means in people's daily life and the work, the thing that eighties of last century need be met or letter could solve, only need a phone just to settle now, especially in today of the Internet fast development, the further conversation cost that reduced of VOIP, speech becomes the preferred manner of periodic traffic with its real-time, low cost and high efficiency.

But this means of communication easily also is a double-edged sword, simultaneously easily, in advance and inconsistent unclear in other words afterwards, has so just brought up unnecessary trouble and dispute on to the elaboration of event.And modern society is increasingly competitive, and " service " indulged multiple enterprises and be considered as " existence originally ", and phone has also become main media and the means that good service is provided.These service procedures of supervision and oversight how effectively become the important topic of present many enterprises.Particularly in special fields such as electric power, traffic scheduling, public security, flood control warnings, the generating process of phonological working is all needed to have a more accurate and reliable recording process.

Therefore recording system arises at the historic moment, and temporarily addresses this problem by recording, as the solution of traditional recorder, automaticity is poor, and the little inquiry of memory space is inconvenient, and needs to want every circuit all to be equipped with a relevant device, the cost height, efficient is low, so this kind mode is inadvisable.

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
