Streaming Statistics
Max MOS LQK Baseline or highest MOS LQK score observed from
start of the voice stream.
These codecs provide the following maximum MOS
LQK score under normal conditions with no frame
loss:
• G.711 gives 4.5
• G.722 gives 4.5
• G.728/iLBC gives 3.9
• G.729 A/AB gives 3.8
MOS LQK Version Version of the Cisco proprietary algorithm used to
calculate MOS LQK scores.
Cumulative Conceal
Ratio
Total number of concealment frames divided by total
number of speech frames received from start of the
voice stream.
Interval Conceal Ratio Ratio of concealment frames to speech frames in
preceding 3-second interval of active speech. If using
voice activity detection (VAD), a longer interval might
be required to accumulate 3 seconds of active speech.
Max Conceal Ratio Highest interval concealment ratio from start of the
voice stream.
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.
