Stream Statistics Items
Description
Domain of the phone
Port number of the destination
Port number of the phone
Number of times the phone has started receiving a stream
Host name for the phone
Number of RTP voice packets transmitted since voice stream was
opened
Note
Type of audio encoding used for the stream: G.729, G.711 u-law,
G.711 A-law, or Lin16k
Internal time stamp indicating when this streaming statistics report
was generated
Total number of octets received by the phone
Number of missing RTP packets (lost in transit)
Number of times this streaming statistics report has been accessed
from the web page (resets when the phone resets)
Score that is an objective estimate of the mean opinion score (MOS)
for listening quality (LQK) that rates from 5 (excellent) to 1 (bad).
This score is based on audible concealment events due to frame loss
in the preceding 8-second interval of the voice stream. For more
information, see the
section on page 10-8
Note
Lowest MOS LQK score observed from start of the voice stream
Version of the Cisco proprietary algorithm used to calculate MOS
LQK scores
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
Number of seconds that have concealment events (lost frames) from
the start of the voice stream (includes severely concealed seconds)
This number is not necessarily identical to the number of
RTP voice packets transmitted since the call began because
the call might have been placed on hold.
"Resolving Voice Quality and Roaming"
The MOS LQK score can vary based on the type of codec
that the Cisco Unified IP Phone uses.
