People keep talking about gateway's but I'm talking about endpoints that do ICE and DTLS-SRTP but don't do RTCP. They also don't do video. The reason they don't do RTCP is because they don't perceive a value in it. I'm not arguing this is right or wrong, I'm just saying they don't see the value. The point the folks that think this is a good idea make is that if RTCP says there is X jitter, or Y % packet loss, there is nothing they can do with this. They will not stop the call until the audio is so bad that user hangs up. Only the user hanging up stops the call. Thus the only thing RTCP does is cause more congestion. Again, not saying this is right but given that most the audio only RTP I see on the network does not have RTCP, I don't think this is likely to change any time soon. And I want to say again, for video it is the opposite story, the bulk of the interactive video RTP I see has RTCP.
