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 DHCP Server” section on page 2-25.
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 Profile.
Step 2 Scroll to the profile name that you want to configure and press Select.
Step 3 Enter **# to unlock the profile and press Edit.
Handset Only Mode Yes—Indicates that the speakerphone is
disabled on the phone
No—Indicates that the speakerphone is
enabled on the phone
