5005

IANA assigns UDP port 5005 the service name avt-profile-2 and describes it as “RTP control protocol.” RFC 3551 defines the RTP/AVP profile for RTP and its associated control protocol, RTCP, in audio and video conferences. The supplied evidence does not establish whether a particular host uses this port or whether it should be publicly reachable, so exposure is Unknown.

RFC 3551 says the profile supports RTP over unicast and multicast UDP as well as TCP. That describes transport options for the profile; it does not show that UDP port 5005 is a universal or required RTCP endpoint. The RFC also notes that a profile may be used without explicit indication by port number, so identify actual traffic from packet and session context rather than the port assignment alone.
