Chapter 7 Viewing Model Information, Status, and Statistics on the Cisco Unified IP Phone Status Menu Table 7-6 Call Statistics Items (continued) Item MOS LQK Version Cumulative Conceal Ratio Interval Conceal Ratio Max Conceal Ratio Conceal Secs Severely Conceal Secs Latency Network Protocol Description Version of the Cisco proprietary algorithm used to calculate MOS LQK scores. Total number of concealment frames divided by total number of speech frames received from start of the voice stream. 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. Highest interval concealment ratio from start of the voice stream. Number of seconds that have concealment events (lost frames) from the start of the voice stream (includes severely concealed seconds). Number of seconds that have more than 5 percent concealment events (lost frames) from the start of the voice stream. Estimate of the network latency, expressed in milliseconds. Represents a running average of the round-trip delay, measured when RTCP receiver report blocks are received. Identifies the current Network Protocol-IPv4.
