Description
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
•
Version of the Cisco proprietary algorithm used to
calculate MOS LQK scores.
Total number of concealment frames divided by total
number of speech frames received from start of the
voice stream.
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.
Highest interval concealment ratio from start of the
voice stream.
Number of seconds that have concealment events (lost
frames) from the start of the voice stream (includes
severely concealed seconds).
concealment events (lost frames) from the start of the
voice stream.

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.
Maximum value of instantaneous jitter, in
milliseconds.
RTP packet size, in milliseconds, for the transmitted
stream.
Number of times RTCP Sender Reports have been

Last time at which an RTCP Sender Report was
1
received.
RTP packet size, in milliseconds, for the received
stream.
RTP packets received from network but discarded from
jitter buffers.
