[OpenSIPS-Users] Mediaproxy customization

[Faheem]

Thanks for quick reply,

Can you please suggest me, if there are any alternatives to get rtp/rtcp stream for each call. I actually need to parse the RTCPs passing from media-proxy and just implement my custom logic to store them in DB.

MediaProxy will insert a conntrack rule as soon as it receives a single RTP packet from each side, so the got_data function will be called a couple of times and never again (unless there are changes in the stream that require destroying the conntrack rule).

You will not get the RTCP packets in your hook as they will be handled by the kernel.
