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 10-12 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 • Monitoring the Voice Quality of Calls, page 10-12 Cisco Unified Wireless IP Phone 7921G Administration Guide for Cisco Unified Communications Manager Release 7.0 9-6 OL-15985-01
