Chapter 5 Configuring Settings on the Cisco Unified Wireless IP Phone 7925G
Configuring Network Profile Settings
Configuring DHCP Settings
The Cisco Unified IP Phones enable DHCP, by default, to automatically assign IP addresses to devices
when you connect them to the network. If you do not use DHCP in your network, then you must disable
DHCP and manually enter the network configuration information. For more information, see
“Interacting with the Dynamic Host Configuration Protocol Server” section on page 2-15.
Use these guidelines when manually configuring the IP settings:
• Ensure the TFTP server has an IP address.
• Ensure the default router IP address is on the same subnet as the host IP address.
Note When DHCP is enabled, you cannot configure IP settings, but you can configure and alternate TFTP
server.
Disabling DHCP
To disable DHCP on the phone and manually configure IP settings, follow these steps:
Procedure
Step 1 Choose SETTINGS >Network Profiles.
Step 2 Scroll to the profile name that you want to configure and press the View softkey.
Step 3 Enter **# to unlock the profile and press the softkey to change.
Step 4 Select Network Configuration. Press View.
Step 5 Scroll to DHCP Enabled and press No.
Step 6 Scroll to IP Address and press Select.
Step 7 In the New IP Address: field, enter the static IP address for the phone.
Step 8 Press Options > Validate to save the entry or press Cancel.
You must enter the other required static fields. See Table 5-2 for descriptions of these fields.
For information about entering values, see the “Guidelines for Editing Settings in the Network Profile”
section on page 5-4.
