Description
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.
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.
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).
Number of seconds that have more than 5 percent 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 received.
Last time at which an RTCP Sender Report was received.
RTP packet size, in milliseconds, for the received stream.
RTP packets received from network but discarded from jitter buffers.
Number of times RTCP Receiver Reports have been received.
Last time at which an RTCP Receiver Report was received.
