Points to note:

  • The QoS column in the show rtp sessions output has no asterisk (*), indicating that no metrics exceeded their event thresholds or average thresholds during the session [1].

  • The QoS is described as Ok because there were no QoS problems [2]

  • All average metric values are below the average thresholds [4] [5] [6] [8] [10] [12] [14] [16]

  • All event counters are zero [3] [5] [7] [9] [11] [13] [15] [17]
