Chapter 7 Viewing Model Information, Status, and Statistics on the Cisco Unified IP Phone Status Menu Table 7-6 Call Statistics Items (continued) Item Description MOS LQK Version Version of the Cisco proprietary algorithm used to calculate 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. Max Conceal Ratio Highest interval concealment ratio from start of the voice stream. Conceal Secs Number of seconds that have concealment events (lost frames) from the start of the voice stream (includes severely concealed seconds). Severely Conceal Secs Latency1 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. Network Protocol Identifies the current Network Protocol-IPv4. 1. When the RTP Control Protocol is disabled, no data generates for this field and thus displays as 0.
