numbers are specified via explicit, separate parameters (using a signaling protocol or other means), the
application MAY disregard the restrictions that the port numbers be even/odd and consecutive
although the use of an even/odd port pair is still encouraged. The RTP and RTCP port numbers MUST
NOT be the same since RTP relies on the port numbers to demultiplex the RTP data and RTCP control
streams.
In a unicast session, both participants need to identify a port pair for receiving RTP and RTCP packets.
Both participants MAY use the same port pair. A participant MUST NOT assume that the source port
of the incoming RTP or RTCP packet can be used as the destination port for outgoing RTP or RTCP
packets. When RTP data packets are being sent in both directions, each participant's RTCP SR packets
MUST be sent to the port that the other participant has specified for reception of RTCP. The RTCP SR
packets combine sender information for the outgoing data plus reception report information for the
incoming data. If a side is not actively sending data (see
), an RTCP RR packet is sent instead.
