Stream Statistics

		Table 8-6	Stream Statistics Items (continued)
		Item		Description
		Receiver Packets		Number of RTP voice packets received since voice
				stream was opened
				Note This number is not necessarily identical to
				the number of RTP voice packets received
				since the call began because the call might
				have been placed on hold.
		Receiver Octets		Total number of octets received by the phone
		Receiver Tool		Type of audio encoding used for the stream: G.729,
				G.711 u-law, G.711 A-law, or Lin16k
		Receiver Lost Packets		Number of missing RTP packets (lost in transit)
		Receiver Jitter		Maximum RTP packet jitter (dynamic delay that a
				packet encounters when going through the network)
				observed since the receiving voice stream was
				opened
		Receiver Reports		Number of times this streaming statistics report has
				been accessed from the web page (resets when the
				phone resets)
		Receiver Start Time		Internal time stamp indicating when Cisco Unified
				CallManager requested that the phone start receiving
				packets
		Voice Quality Metrics
		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 9-17
				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
