I started the work, this could have need handled by a Kamailio module, before concluding that it would only work with a few endpoints since the fact that an endpoint advertise this SDP param does not mean that it is supporting it when sending.

WIP on a Kamailio module, not sure how far I went before concluding limited support was not viable for me.

Anything is possible, but how do you see this being a Kamailio issue?

Kamailio isn’t involved in proxying media and if you use
RTPengine or RTPproxy RTCP packets are handled like RTP packets.

Check with the vendors of your devices.
