Description
Sender Report Time
Internal time stamp indication when the last RTCP Sender Report was sent.
1
Sent
Rcvr Lost Packets
Total number of RTP data packets that have been lost since starting receiving
data 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 duplicate. The value displays as 0 if the
connection was set to send-only mode.
Avg Jitter
Estimate of mean deviation of the RTP data packet inter-arrival time,
measured in milliseconds. The value displays as 0 if the connection was set
to send-only mode.
Rcvr Codec
Type of audio encoding used for the received stream.
1
Rcvr Reports Sent
Number of times the RTCP Receiver Reports have been sent.

Rcvr Packets
Total number of RTP data packets received by the phone since starting
receiving data on this connection. Includes packets received from different
sources if this is a multicast call. The value displays as 0 if the connection was
set to send-only mode.
Rcvr Octets
Total number of payload octets received in RTP data packets by the device
since starting reception on the connection. Includes packets received from
different sources if this is a multicast call. The value displays as 0 if the
connection was set to send-only mode.
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
Note
Avg MOS LQK
Average MOS LQK score observed for the entire voice stream.
Min MOS LQK
Lowest MOS LQK score observed from start of the voice stream.
Max MOS LQK
Baseline or highest MOS LQK score observed from start of the voice stream.
These codecs provide the following maximum MOS LQK score under normal
conditions with no frame loss:
MOS LQK Version
Version of the Cisco proprietary algorithm used to calculate MOS LQK
scores.
Cumulative Conceal
Total number of concealment frames divided by total number of speech
Ratio
frames received from start of the voice stream.
OL-12641-01
The MOS LQK score can vary based on the type of codec that the
Cisco Unified IP Phone uses.
G.711 gives 4.5
•
G.722 gives 4.5
•
G.728/iLBC gives 3.9
•
•
G.729 A/AB gives 3.8
