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
Communications Manager 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
Step 2
Step 3
Step 4
Choose Device > Phone.
Specify the criteria to find the phone and click Find, or click Find to display a list of all phones.
Click the device name to open the Phone Configuration window for the device.
Scroll down to the Product Specific Configuration section. 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

A Cisco Unified IP Phone can stream information to and from up to three devices simultaneously. A
phone streams information when it is on a a call or running a service that sends or receives audio or data.
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.
To display a Streaming Statistics 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 Stream 1, the Stream 2, the Stream
