Thanks a lot. Then let me describe what i am doing. In VoIP networks, One of the ways to solve the one-way audio issue is TURN. In this case both endpoint have to send their media (voice as RTP) to server. In this conditions the server works as B2BUA. Because of the server is processing the media (get media from one hand and relay it to another hand), It usages a lot of resource of server. So I am implementing a new module to do this in kernel level. I test this idea in my laboratory by adding conntrack entry manually in server and all things works great. But i need to get more idea to do this project in best way and high performance, because the QoS very importance in VoIP networks. What is the best way? Let me know more about this.
