Streaming Statistics
Table 8-5 Streaming Statistics Area Items (continued)
Item Description
Sender Packets Total number of RTP data packets transmitted by the phone since starting this connection. The value
is 0 if the connection is set to receive only mode.
Sender Octets Total number of payload octets transmitted in RTP data packets by the phone since starting this
connection. The value is 0 if the connection is set to receive only mode.
Sender Codec Type of audio encoding used for the transmitted stream.
1
Sender Reports Sent Number of times the RTCP Sender Reports have been sent.
Sender Report Time Internal time stamp indicating when a 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 Report Time Internal time stamp indicating when a RTCP Receiver Report was sent.

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 Voice Quality of Calls, 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 frames received from start
Ratio of the voice stream.

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.729 A /AB gives 3.8
•
G.728/iLBC gives 3.9
