Firmware Versions

You can verify the firmware versions that are used on the Cisco Unified Wireless IP Phone by viewing the
Firmware Info screen. The firmware version name is in this format:
Product_Name-Model-Protocol.Version Number.Filetype
Description
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
Quality Monitoring, on page
The MOS LQK score can vary based on the type of codec that the
Note
Cisco Unified IP Phone uses.
Average MOS LQK score observed for the entire voice stream.
Lowest MOS LQK score observed from start of the voice stream.
Baseline or highest MOS LQK score observed from start of the voice
stream.
These codecs provide the following maximum MOS LQK score under
normal conditions with no frame loss:
• G.711 gives 4.5
• G.729 A /AB gives 3.7
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.
Information about outbound and inbound previous and current frames.
