Hadriel, |..., when it can send packets back. This looks open for interpretation since there can be other reasons apart from congestions where the mirror can't send packets back. My suggestion is to state explicitly that congestion in the only exception: A loopback mirror that is compliant to this specification and accepts media with rtp-pkt-loopback loopback-type MUST loopback the incoming RTP packets using either the encapsulated RTP payload format or the direct loopback RTP payload format as defined in section 7 of this specification, except when the loopback mirror perceives congestion. When the loopback mirror perceives congestion it might not necessarily loopback all incoming RTP packets.
