Streaming Statistics
Conceal Secs Number of seconds that have concealment events (lost frames) from the start
of the voice stream (includes severely concealed seconds).
Severely Conceal Secs Number of seconds that have more than 5 percent concealment events (lost
frames) from the start of the voice stream.
Latency
1
Estimate of the network latency, expressed in milliseconds. Represents a
running average of the round-trip delay, measured when RTCP receiver report
blocks are received.
Max Jitter Maximum value of instantaneous jitter, in milliseconds.
Sender Size RTP packet size, in milliseconds, for the transmitted stream.
Sender Reports
Received
1
Number of times RTCP Sender Reports have been received.
Sender Report Time
Received
1
Last time at which an RTCP Sender Report was received.
Rcvr Size RTP packet size, in milliseconds, for the received stream.
Rcvr Discarded RTP packets received from network but discarded from jitter buffers.
Rcvr Reports
Received
1
Number of times RTCP Receiver Reports have been received.
Rcvr Report Time
Received
1
Last time at which an RTCP Receiver Report was received.
Voice Quality Metrics
MOS LQK Score that is an objective estimate of the mean opinion score (MOS) for
listening quality (LQK) that rates from 5 (excellent) to 1
(bad). This score is
based on audible concealment events due to frame loss in the preceding
8-second interval of the voice stream. For more information, see the
“Monitoring the Voice Quality of Calls” section on page 9-21.
The MOS LQK score can vary based on the type of codec that the Cisco
Unified IP Phone uses.
Avg MOS LQK Average MOS LQK score observed for the entire voice stream.
Min MOS LQK Lowest MOS LQK score observed from start of the voice stream.
