Chapter 9 Monitoring the Cisco Unified Wireless IP Phone Remotely Stream Statistics Table 9-6 Stream Statistics Items Item RTP Statistics Domain Name Remote Port Local Port Receiver Joins Host Name Sender Packets Sender Tool Sender Report Time Receiver Octets Receiver Lost Packets Receiver Reports Voice Quality Metrics MOS LQK Min MOS LQK MOS LQK Version Interval Conceal Ratio Conceal Secs Description Domain of the phone Port number of the destination Port number of the phone Number of times the phone has started receiving a stream Host name for the phone Number of RTP voice packets transmitted since voice stream was opened Note This number is not necessarily identical to the number of RTP voice packets transmitted since the call began because the call might have been placed on hold. Type of audio encoding used for the stream: G.729, G.711 u-law, G.711 A-law, or Lin16k Internal time stamp indicating when this streaming statistics report was generated Total number of octets received by the phone Number of missing RTP packets (lost in transit) Number of times this streaming statistics report has been accessed from the web page (resets when the phone resets) 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 "Resolving Voice Quality and Roaming" section on page 10-8 Note The MOS LQK score can vary based on the type of codec that the Cisco Unified IP Phone uses. Lowest MOS LQK score observed from start of the voice stream Version of the Cisco proprietary algorithm used to calculate MOS LQK scores 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 Number of seconds that have concealment events (lost frames) from the start of the voice stream (includes severely concealed seconds) Related Topic • Resolving Voice Quality and Roaming, page 10-8 OL-15984-01 Cisco Unified Wireless IP Phone 7925G Administration Guide for Cisco Unified Communications Manager 7.0(1) 9-11
