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 Codec		Type of audio encoding used for the transmitted stream.

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 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.

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.

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:
		• G.711 gives 4.5
		• G.729 A /AB gives 3.7
