Streaming Statistics

Table 8-5			Streaming Statistics Area Items (continued)
	Item			Description
	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/video encoding used for the transmitted stream.
	Sender Reports Sent1			Number of times the RTCP Sender Report have been sent.
	Sender Report Time Sent1			Internal time stamp indication when the last RTCP Sender Report was 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/video encoding used for the received stream.
	Rcvr Reports Sent1			Number of times the RTCP Receiver Reports have been sent.
	Rcvr Report Time Sent1			Internal time stamp indication when a RTCP Receiver Report was 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			Objective estimate of the Mean Opinion Score (MOS) for Listening Quality (LQK) that
				ranks audio quality from 5 (excellent) to 1 (bad). This score is based on
				audible-concealment events due to a frame loss in the preceding 8 seconds of the voice
				stream.
				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 for the entire voice stream.
	Min MOS LQK			Lowest MOS LQK score from the start of the voice stream.
	Max MOS LQK			Baseline or highest MOS LQK score from the start of the voice stream.
				The following codecs provide the corresponding maximum MOS LQK scores under
				normal conditions with no frame loss:
				•	G.711: 4.5
				•	G.722: 4.5
				•	G.728/iLBC: 3.9
				•	G729A/AB: 3.7
	MOS LQK Version			Version of the Cisco-proprietary algorithm used to calculate the MOS LQK scores.
	Cumulative Conceal Ratio			Total number of concealment frames divided by total number of speech frames received
				from start of the voice stream.
	Interval Conceal Ratio			Ratio of concealment frames to speech frames in preceding 3-second interval of active
				speech. If using voice activity detection (VAD), a longer interval might be required to
				accumulate 3 seconds of active speech.
