example

[0029] Example: combine image 3 with Figure 4 , set the calling user as the recording user, the called user as the common user, and configure two recording servers. Then, a method for realizing hot backup of a softswitch recording system comprises the following steps:

[0030] S1: Configure two recording servers in the data configuration of the softswitch device, and both recording servers are registered to the softswitch device;

[0031] S2: The calling user initiates a call request to the softswitch, and the call request carries calling number, called number and SDP (Session Description Protocol, Session Description Protocol) information;

[0032] The SDP information includes: the IP address of the calling RTP stream, the RTP port, and the voice codec capability.

[0033] S3: After the softswitch receives the call request, it first authenticates the calling user. After passing the authentication, it checks the service attributes of the calling user and the called user t...

Abstract

The invention discloses a method for realizing hot backup of a softswitch recording system, and relates to the field of softswitch communication. Based on the centralized recording mode, the present invention configures more than two recording servers in the softswitch, and then applies for at least 4 recording ports to the media server; after the recording port application is successful, the calling user and the called user will call The RTP stream and the called RTP stream are respectively sent to the corresponding recording ports of the media server; the media server sends the received calling RTP stream and called RTP stream to each recording server respectively. Compared with the distributed method, the present invention effectively reduces the cost of the recording system; as long as one of the multiple recording servers works normally, the complete RTP stream can be saved, thereby improving the reliability of the recording system and realizing the whole network Hot backup for recording systems.

Description

technical field [0001] The invention relates to the field of softswitch communication, in particular to a method for realizing hot backup of a centralized softswitch recording system. Background technique [0002] The softswitch system is based on VOIP technology and realizes distributed deployment through IP network. In the softswitch system, the voices of terminals and terminal or gateway devices are transmitted on the network through RTP (Realtime Transport Protocol). During the call process, when the calling party initiates a call, the SDP data carried in the calling protocol includes the IP address and RTP port of the calling party's media stream. After performing call control operations such as number analysis and route selection, the softswitch forwards the calling party's media stream information to the called party. After the called media negotiation, the call response message carries the IP address and RTP port of the called media stream, and the softswitch forwa...
