I am building an application with gstreamer-webrtc in which timestamp in RTCP and RTP is crucial.  
while using a mediaserver SFU (mediasoup) the media server consumes and consumes/terminates and produces its own RTCP packets.  
[Forwarding NTP timestamp from source - #4 by ibc](https://mediasoup.discourse.group/t/forwarding-ntp-timestamp-from-source/3427/4).  
I need the original RTCP packets. is there any other SFU that does not consumes/terminates the RTCP and just relay it like a Turn server and SFU combination.
