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 Phones 7970G/7971G-GE, 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 8-3

• Device Information, page 8-4

Phone. Phones registered with Cisco Unified CallManager display the IP

address at the top of the Phone Configuration web page.

• On the phone, press the Settings button, choose 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

The web page for a Cisco Unified IP Phones 7970G/7971G-GE includes these hyperlinks:

Streaming Statistics

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, or the Stream 3 hyperlink.
