TxCnt Number of RTP voice packets transmitted since
voice stream was opened.
Note 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.
Avg Jtr Estimated average RTP packet jitter (dynamic delay
that a packet encounters when going through the
network) observed since the receiving voice stream
was opened.
Max Jtr Maximum jitter observed since the receiving voice
stream was opened.
RxDisc Number of RTP packets in the receiving voice stream
that have been discarded (bad packets, too late, and
so on).

comfort noise packets that are generated by
Cisco Gateways, which will increment this
counter.
RxLost Missing RTP packets (lost in transit).
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 9-24 .
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.
