Hi team,

Great work you did. Any plan for adding RTPEngine is there?

Thanks.

Thank you! Depends what are you going to do ? NGCP ?

Actually, I am using the subscribe mechanism of RTPEngine for SIPREC, I thought that eBPF would be great for forking. Do you agree?

@hyavari interesting! we don't use this feature, so please feel free to share some examples for us to get inspired :)

In my current SIPREC server, I am sending subscribe request and answer to RTPEngine and then record forked streams. But I think what if we use your approach, eBPF I mean, and just filter streams based on IP and ports in the kernel level, and then in userspace remove IP headers and use the payload and etc. (I am just thinking loudly!)

looks really interesting, yes, it can be possible by using XDP packet inspection and the receive function of RTPEngine.
