Metric Parameter Description
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
MOSCQ 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
MOSCQEstAlg MOS-CQ Est. Algorithm - name (string) of the
algorithm used to estimate MOSCQ
QoEEstAlg QoE Est. Algorithm - name (string) of the algorithm
used to estimate all voice quality metrics
DialogID - Identification of the SIP dialog with which the media
session is related
Below shows an example of a SIP PUBLISH message sent with RTCP XR and QoE information:
