Signal 
SL  Signal Level (dB) - ratio of the signal level to a 0 dBm0 reference 
NL  Noise Level (dB) - ratio of the silent period background noise level 
to a 0 dBm0 reference

signal and the echo level as measured after echo cancellation or 
suppression has been applied. 
QualityEst 
RLQ  Listening Quality R - listening quality expressed as an R factor (0-
95 for narrowband calls and 0-120 for wideband calls) 
RLQEstAlg  RLQ Est. Algorithm - name (string) of the algorithm used to 
estimate RLQ 
RCQ  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) 
RCQEstAlg  RCQ Est. Algorithm - name (string) of the algorithm used to 
estimate RCQ 
EXTRI  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) 
ExtRIEstAlg  Ext. R In Est. Algorithm - name (string) of the algorithm used to 
estimate EXTRI 
EXTRO  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) 
ExtROEstAlg  Ext. R Out Est. Algorithm - name (string) of the algorithm used to 
estimate EXTRO 
MOSLQ  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 
MOSLQEstAlg  MOS-LQ Est. Algorithm - name (string) of the algorithm used to 
estimate MOSLQ
