Description

 

 

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.

 

 

Rcvr Reports Sent1

Number of times the RTCP Receiver Reports have been sent.

Rcvr Report Time

Internal time stamp indicating when a RTCP Receiver Report was sent.

Sent1

 

 

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 9-20.

 

 

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.

 

 

 

Min MOS LQK

 

Lowest MOS LQK score observed from start of the voice stream.
