Hello Everyone, Since last my email about optimization hiops module for kamailio, I am thinking about new approach of relaying RTP (media) in Kamailio. I know there are some modules like RTPEngine, RTPProxy and rtp_media_server in Kamailio. All those modules are in TURN concept of NAT-Traversal in vioce over ip networks. Suppose there is no needed for transcoding in some calls, then those modules get RTP packets from one hand and relay them to another hand. This activities (with no transcoding) could be done by just forwarding RTP-packet in third level of networks,too. Just like as connection tracking have been doing in Linux Kernel. The RTPEngine use Linux Kernel, But it is different from my own idea. Actually i have written another module in Kamailio (light-rtp-engine or lre) for checking this concept. it works great.It increase concurrent of calls rather than other modules in the same situation (no transcoding situation). Now i want to integrate this module with all other RTP-engine module in Kamailio, For example in some situation that the call no need for transcoding, the module runs as upper layer on other RTP modules and active forwarding packet by add new rule in Linux Kernel connection tracking. Now i need to get some idea of working this module with other RTP module in Kamailio. Do you have any idea in regard of this module works as upper layer on other RTP-modules? Do you have better idea of using this new approach of relaying RTP in Kamailio? With Best Regards.
Hi, if I understand you wrote a module that is using libnetfilter. I think I understand what you did since I used this library to build a VoIP network impairment simulator https://github.com/jchavanton/disruptor
The RTP media server module is using the oRTP library that does manage the UDP transmissions, sockets are handled/abstrated in RTP sessions. On top of my head, I can not imagine a abstraction layer and what kind of value we would get.
My first impression would be to choose between one or the other depending on the use case.
