Remote Monitoring

This chapter describes the methods for monitoring the Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G using a web page.

Access web page for phone

To access the web page for a Cisco Unified Wireless IP Phone, perform the following steps.

Procedure
    Step 1   Obtain the IP address of the Cisco Unified Wireless IP Phone using one of these methods:
    • Search for the phone in Cisco Unified Communications Manager by choosing Devices > Phones. Phones that are registered with Cisco Unified Communications Manager display the IP address on the Find and List Phones web page and at the top of the Phone Configuration web page.
    • On the Cisco Unified Wireless IP Phone, press SETTINGS > Device Information > Network and then scroll to the IP Address option.
    Step 2   Open a web browser and enter the following URL:

    https://<IP_address>

    where IP_address is the IP address of the Cisco Unified Wireless IP Phone

    Note   

    Step 3   If the Security Alert dialog box displays a notice to accept the Trust Certificate, click Yes or Always to accept the application.
    Step 4   Log in to the web pages with username admin and enter the password Cisco for the phone web pages.
