Cumulative conceal ratio	Total number of concealment frames divided by total number of speech frames received from the 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.
Severely conceal seconds	Number of seconds that have more than 5 percent concealment events (lost frames) from the start of the voice stream.
Latency	Delay time in audio transmission.
MOS-LQ	Mean Opinion Score for Listening Quality (MOS-LQ) represents the estimated subjective quality of the received audio.
MOS-CQ	Mean Opinion Score for Conversational Quality (MOS-CQ) evaluates the bidirectional quality of a voice session, incorporating the effects of mouth-to-ear latency and packet loss on the conversation.

Table 5. Submenu: Trace settings
Field	Description
Remote syslog	Displays whether remote system logging is enabled or not.
Log profile	Displays the type of logging.
Additional debug logs	Displays the device log information.

You can configure the Remote Log, Log Profile, and Log Server settings on Cisco Unified CM. Once configured, the Remote syslog, Log profile, and Additional debugs fields on the phone will update to reflect your settings.

System configuration

The System configuration menu on the phone displays key security settings, including the web access, web admin, security mode, certificate status, and trust list. It enables administrators and users to monitor and manage the phone’s security configuration effectively. Fields in the submenus vary slightly depending on the call control system that the phone is registered to.
