Remotely  
Each Cisco Unified IP Phone has a web page from which you can view a variety  
of information about the phone, including:  
Device information  
Network configuration information  
Network statistics  
Device logs  
Streaming statistics  
This chapter describes the information that you can obtain from the phone’s web  
page. You can use this information to remotely monitor the operation of a phone  
and to assist with troubleshooting.  
You can also obtain much of this information directly from a phone. For more  
information, see Chapter 7, “Viewing Model Information, Status, and Statistics  
on the Cisco Unified IP Phone.”  
For more information about troubleshooting the Cisco Unified IP Phone,

The streaming statistics areas on a phone’s web page provide information about  
the streams. Most calls use only one stream (Stream 1), but some calls use two or  
three stream. For example, a barged call uses Stream 1 and Stream 2.

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 the  
“Monitoring the Voice Quality of Calls” section on page 9-21.  
Note  
The MOS LQK score can vary based on the type of codec that the

Min MOS LQK  
Max MOS LQK  
Average MOS LQK score observed for the entire voice stream.  
Lowest MOS LQK score observed from start of the voice stream.

Cumulative Conceal  
Ratio
