<br>
On February last year there was a discussion related to proxy_media mode and RTCP and I understood this is not actually supported.<br>
<br>
I am actually facing the same issue and I would like to understand if there is any way to get it working; since RTP is using an even port and RTCP the following one (RTP port + 1), is there any way to get both ports proxied? <br>
