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 7931G,
see Chapter 9, “Troubleshooting and Maintenance.”
This chapter includes these topics:
•Accessing the Web Page for a Phone, page 8-2
•Disabling and Enabling Web Page Access, page 8-4
•Device Information, page 8-4
•Network Configuration, page 8-6

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 8-4 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
Administration by choosing Device > Phone. Phones registered with
Cisco Unified Communications Manager display the IP address at the top of
the Phone Configuration window.
•On the phone, take either of these actions:
– If the phone is registered with Cisco Unified Communications Manager,
press the Application Menu button, choose Settings >
Network Configuration, and then scroll to the IP Address option.
By default, the Application Menu button is line button 24 (the top left
line button).
– If the phone is not registered with Cisco Unified Communications
Manager, press the Settings softkey, choose Network Configuration,
and then scroll to the IP Address option.
The Settings softkey appears only when the phone is not registered.
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 phone’s 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:
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 From the Web Access drop-down list box, choose Disabled.
Step 5 Click Update.
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.
Device Information
The Device Information area on a phone’s web page displays device settings and
related information for the phone. Table 8-1 describes these items.
To display the Device Information area, access the web page for the phone as
described in the “Accessing the Web Page for a Phone” section on page 8-2, and
then click the Device Information hyperlink.

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

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:
