Problems solved by technology

Therefore, the implementation of call monitoring in the prior art heavily depends on the additional processing capability of the equipment being monitored
However, most of the IP phones supporting the SIP protocol in the current VoIP network do not have the above-mentioned capabilities, so the application of call monitoring in the prior art is greatly restricted.
Moreover, in the monitoring process of the prior art, the monitored party needs to send media streams to two destination addresses (the opposite end of the voice call and the monitoring party), thereby increasing the transmission bandwidth of the data, and causing the monitored party to easily perceive that he is being monitored. monitor

Embodiment Construction

[0058] The present invention provides a brand-new method and device for call monitoring. When the monitoring party initiates a call monitoring request, the SIP server uses the media update request to initiate a session update to both calling parties, modify the media destination address, and make the calling parties transfer the media stream Both are sent to the monitoring party, and the monitoring party forwards the media stream between the two parties of the call. While forwarding the media stream, the monitoring party can monitor the media stream of either party or both parties of the call. Since the monitoring does not rely on the additional processing capability of the equipment of the monitored party, the present invention can be implemented only if the monitored party supports the SIP protocol, and since the amount of data sent by the monitored party does not change significantly, it is difficult for the monitored party to find out himself being monitored. The present i...

Abstract

The invention provides a method and equipment for monitoring a call made via a voice over Internet protocol. In the method, a monitoring side forwards a media stream called by the VoIP of a monitored side and monitors the monitored side in a forwarding process. The method and the equipment can monitor calls without requiring the audio mixing capacity of the equipment on the monitored side and synchronous transmission of two paths of multimedia streams of the equipment on the monitored side.

Description

technical field [0001] The invention relates to the technical field of Voice over Internet Protocol (VoIP, Voice over Internet Protocol), in particular to a monitoring method and equipment for a VoIP call. Background technique [0002] VoIP is based on the IP packet switching network. Through a series of processing such as digitizing, compressing, packaging, and encapsulating the traditional analog voice signal, the voice service can be carried by the IP network. The VoIP technology based on Session Initiation Protocol (SIP, Session Initiation Protocol) has been widely used at present. [0003] The monitoring function of VoIP calls is an important voice supplementary service in VoIP. Its networking applications are as follows: figure 1 shown. The first client, the second client and the third client are all connected to the SIP server, and the SIP server is mainly used to forward and process voice signaling. The first client, the second client and the third client may be I...
