Cisco Unified Wireless IP Phone 7921G Administration Guide for Cisco Unified CallManager Release 4.1, 4.2, 5.0
OL-10802-02
Receiver Packets Number of RTP voice packets received since voice
stream was opened
Note This number is not necessarily identical to
the number of RTP voice packets received
since the call began because the call might
have been placed on hold.
Receiver Octets Total number of octets received by the phone
Receiver Tool Type of audio encoding used for the stream: G.729,
G.711 u-law, G.711 A-law, or Lin16k
Receiver Lost Packets Number of missing RTP packets (lost in transit)
Receiver Jitter Maximum RTP packet jitter (dynamic delay that a
packet encounters when going through the network)
observed since the receiving voice stream was
opened
Receiver Reports Number of times this streaming statistics report has
been accessed from the web page (resets when the
phone resets)
Receiver Start Time Internal time stamp indicating when Cisco Unified
CallManager requested that the phone start receiving

Voice Quality Metrics
MOS LQK 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
“Monitoring
the Voice Quality of Calls” section on page 9-17
Note The MOS LQK score can vary based on the
type of codec that the
Cisco
Unified IP Phone uses.
Avg MOS LQK Average MOS LQK score observed for the entire
voice stream
