Despite its DESCRIPTION text in the source MIB being a copy-paste artifact reading "Destination Udp RTCP port," this object's name and position in the table indicate it is actually a session identifier for this snooped VoIP session. An admin or management application would use it to uniquely reference this specific VoIP session when correlating it with other records or logs, distinct from the RTP/RTCP port fields already captured elsewhere in the same row. As an illustrative example, a management tool logging VoIP sessions would record rlVoipMngSnoopSessionSessionId as a unique numeric tag for this call, separate from the destination RTCP port value which is captured by rlVoipMngSnoopSessionDstUdpRtcp instead.
