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.”

Accessing the Web Page for a Phone
To access the web page for a Cisco Unified IP Phone, perform these steps.
Note If you cannot access the web page, it may be disabled. See the “Disabling and Enabling Web Page
Access” section on page 8-3 for more information.
Procedure
Step 1 Obtain the IP address of the Cisco Unified IP Phone using one of these methods:
• Search for the phone in Cisco Unified Communications Manager by choosing Device > Phone.
Phones registered with Cisco Unified Communications Manager display the IP address on the Find
and List Phones window and at the top of the Phone Configuration window.
• On the Cisco Unified IP Phone, press the Applications button, choose Admin Settings > Network
Configuration, and then scroll to the IP Address option.
Step 2 Open a web browser and enter the following URL, where IP_address is the IP address of the
Cisco Unified IP Phone:
http://IP_address

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 Choose Device > Phone.
Step 2 Specify the criteria to find the phone and click Find, or click Find to display a list of all phones.
Step 3 Click the device name to open the Phone Configuration window for the device.
Step 4 Scroll down to the Product Specific Configuration section. From the Web Access drop-down list box,
choose Disabled.
Step 5 Click Update.
Disabling and Enabling Web Page Access
Note 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.
