Streaming Statistics

Table 8-5	Streaming Statistics Area Items (continued)
Item		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.
