Model Information, Status, and Statistics Overview
This chapter describes how to use the following menus on the Cisco Unified IP Phone 7941G, 7941G-GE,
7942, 7961G-GE, and 7962G to view model information, status messages, and network statistics for the phone:
• Model Information screen: Displays hardware and software information about the phone. For more
information, see Display Model Information Screen, on page 2.
• Status menu: Provides access to screens that display the status messages, network statistics, firmware
versions, and Expansion Module information. For more information, see Status Menu, on page 3.
• Call Statistics screen: Displays counters and statistics for the current call. For more information, see
Call Statistics Screen, on page 15.
You can use the information on these screens to monitor the operation of a phone and to assist with
troubleshooting.
You can also obtain much of this information, and obtain other related information, remotely through the
phone’s web page. For more information, see Remote Monitoring.

Failed
The phone attempted an 802.1X

Authentication typically fails for one of the following
reasons:
• No shared secret is configured in the phone or
authentication server.
• The shared secret configured in the phone and
the authentication server do not match.
• Phone has not been configured in the
authentication server.

Voice Quality Metrics
MOS LQK
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 Voice Quality Monitoring.
Note
The MOS LQK score can vary based on the type of codec that
the Cisco Unified IP Phone uses.
Avg MOS LQK
Average MOS LQK score observed for the entire voice stream.
Min MOS LQK
Lowest MOS LQK score observed from start of the voice stream.
Max MOS LQK
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.722 gives 4.5
• G.728/iLBC gives 3.9
• G.729 A/AB gives 3.8
