End System Delay (msec)
One Way Delay (msec)
Inter-Arrival Jitter (msec)
Mean Absolute Jitter (msec)
Signal Level (dB) - ratio of the signal level to a 0 dBm0 reference
Noise Level (dB) - ratio of the silent period background noise level
to a 0 dBm0 reference
Residual Echo Return Noise (dB) - ratio between the original
signal and the echo level as measured after echo cancellation or
suppression has been applied.
Listening Quality R - listening quality expressed as an R factor (0-
95 for narrowband calls and 0-120 for wideband calls)
RLQ Est. Algorithm - name (string) of the algorithm used to
estimate RLQ
Conversational Quality R - cumulative measurement of voice
quality from the start of the session to the reporting time (R is 0-95
for narrowband calls and 0-120 for wideband calls)
RCQ Est. Algorithm - name (string) of the algorithm used to
estimate RCQ
External R In - voice quality as measured by the local endpoint for
incoming connection on "other" side (R is 0-95 for narrowband
calls and 0-120 for wideband calls)
Ext. R In Est. Algorithm - name (string) of the algorithm used to
estimate EXTRI
External R Out - value is copied from RTCP XR received from the
remote endpoint on the "other" side of this endpoint (R is 0-95 for
narrowband calls and 0-120 for wideband calls)
Ext. R Out Est. Algorithm - name (string) of the algorithm used to
estimate EXTRO
MOS-LQ - estimated mean opinion score for listening voice quality
on a scale from 1 to 5, in which 5 represents excellent and 1
represents unacceptable
MOS-LQ Est. Algorithm - name (string) of the algorithm used to
estimate MOSLQ
MOS-CQ - estimated mean opinion score for conversation voice
quality on a scale from 1 to 5, in which 5 represents excellent and
1 represents unacceptable
estimate MOSCQ
QoE Est. Algorithm - name (string) of the algorithm used to
estimate all voice quality metrics
