Monitoring the Cisco Unified IP Phone 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, Chapter 9, “Troubleshooting  
and Maintenance.”

Disabling and Enabling Web Page Access  
For security purposes, you may choose to prevent access to the web pages for a phone. If you do so, you  
will prevent access to the web pages that are described in this chapter and to the Cisco Unified CM User  
Options web pages.  
To disable access to the web pages for a phone, follow these steps from Cisco Unified Communications  
Manager Administration.  
Procedure  
Step 1

Some features, such as Cisco Quality Report Tool, do not function properly without access to  
the phone web pages. Disabling web access also affects any serviceability application that relies  
on web access, such as CiscoWorks.  
To enable web page access when it is disabled, see the preceding steps about disabling access. Follow  
the same steps, but choose Enabled in Step 4 to enable the web page.
