Network Configuration menu to configure most network settings for the
Cisco Unified IP Phone. For more information about using the Phone
Configuration web page for configuration, see Appendix A, “Additional
Configuration Methods and Parameters.” For information about using the IVR
system for configuration, see Appendix A, “Additional Configuration Methods

Accessing Network Settings through a Phone Configuration Web Page
You can view and set network configuration options for a Cisco Unified IP Phone
7905G and 7912G from the Phone Configuration web page for that phone. To set
options in this web page, you must first use the UIPassword parameter in the
phone profile file to set up a password. If you do not set up a password, you will
not be able to change network settings, and Apply will not be available.
For more information about the UIPassword parameter, see Ta ble A -8 on
page A-23.

Accessing Network Settings through a Phone Configuration Web Page
Note The Phone Configuration web page described in this chapter differs from the User
Options web pages, which gives users control over various phone options and
features, and the Cisco Unified CallManager Administration Phone
Configuration pages, which let you configure many phone functions and features.
For more information about the User Options web pages, refer to the Customizing
Your Cisco Unified IP Phone on the Web. For more information about the
Cisco Unified CallManager Administration Phone Configuration pages, refer to
the Cisco Unified CallManager documentation.
To access the Phone Configuration web page for a phone, follow these steps:
Procedure
Step 1 Open a web browser and enter the following URL, where IPaddress is the IP
address of your phone:
http://IPaddress
On the Cisco Unified IP Phone 7905G and 7912G, you can determine the IP
address by pressing the Menu button, choosing Settings > Network
Configuration, and then scrolling to IP Address.
OL-8617-01
For example, the Phone Configuration web page for a Cisco Unified IP Phone
with the IP address 192.168.3.225 is http://192.168.3.225
Step 2 Press Enter.
The Phone Configuration web page appears.
Note You can control whether users can access the web pages for a phone. For more
information, see the “Disabling Web Page Access” section on page A-8.

Assigning DNS Servers
The DNS setting on the Cisco Unified IP Phone allows you to specify remote
computers by host names, which are character strings with some mnemonic value,
rather than by using IP addresses, which are simply strings of numbers.
The phones use DNS to resolve the host name of TFTP servers,
Cisco Unified CallManager systems, and web server host names when the system
is configured to use names rather than IP addresses.
To assign a DNS server for the Cisco Unified IP Phone, follow these steps:
