Description
Item
Average MOS LQK score that was observed for the entire voice stream.
Avg MOS LQK
Lowest MOS LQK score that was observed from the start of the voice stream.
Min MOS LQK
Baseline or highest MOS LQK score that was 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 yields 4.5.
•
G.729 A /AB yields 3.7.
Max MOS LQK
Version of the Cisco proprietary algorithm that is used to calculate MOS LQK
scores.
MOS LQK Version
Number of seconds that have concealment events (lost frames) from the start
of the voice stream (includes severely concealed seconds).
Conceal Secs
Number of seconds that have more than five percent concealment events (lost
frames) from the start of the voice stream.
Severely Conceal Secs
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.
Latency
(see note)
Maximum value of instantaneous jitter, in milliseconds.
Max Jitter
RTP packet size, in milliseconds, for the transmitted stream.
Sender Size
Number of times RTCP Sender Reports have been received.
Sender Reports Received
(see note)
Most recent time when an RTCP Sender Report was received.
Sender Report Time
Received
(see note)
RTP packet size, in milliseconds, for the received stream.
Rcvr Size
RTP packets that were received from the network but were discarded from the
jitter buffers.
Rcvr Discarded
Number of times RTCP Receiver Reports have been received.
