Description
Item
Internal time-stamp indication as to when the last RTCP Sender Report was
sent.
Sender Report Time Sent
(see note)
Total number of RTP data packets that have been lost since data reception started
on this connection. Defined as the number of expected packets less the number
of packets actually received, where the number of received packets includes any
that are late or are duplicates. The value displays as 0 if the connection was set
to send-only mode.
Rcvr Lost Packets
Estimate of mean deviation of the RTP data packet interarrival time, measured
in milliseconds. The value displays as 0 if the connection was set to send-only
mode.
Avg Jitter
Type of audio encoding that is used for the received stream.
Rcvr Codec
Number of times the RTCP Receiver Reports have been sent.
Rcvr Reports Sent
(see note)
Internal time-stamp indication as to when a RTCP Receiver Report was sent.
Rcvr Report Time Sent
(see note)
Total number of RTP data packets that the phone has received since data
reception started on this connection. Includes packets that were received from
different sources if this call is a multicast call. The value displays as 0 if the
connection was set to send-only mode.
Rcvr Packets
Total number of payload octets that the device received in RTP data packets
since reception started on the connection. Includes packets that were received
from different sources if this call is a multicast call. The value displays as 0 if
the connection was set to send-only mode.
Rcvr Octets
Total number of concealment frames divided by total number of speech frames
that were received from the start of the voice stream.
Cumulative Conceal Ratio
Ratio of concealment frames to speech frames in the preceding 3-second interval
of active speech. If voice activity detection (VAD) is in use, a longer interval
might be required to accumulate three seconds of active speech.
Interval Conceal Ratio
Highest interval concealment ratio from the start of the voice stream.
Max Conceal Ratio
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 that are to frame loss in the preceding eight-second
interval of the voice stream. For more information, see
Monitoring, on page 293
.
The MOS LQK score can vary due to the codec type that the Cisco
Unified IP Phone uses.
