Chapter 4 Configuring Settings on the Cisco Unified IP Phone
Device Configuration Menu
Understanding DHCPv6 and Autoconfiguration
You can choose to configure the IP address and other network settings, such as the TFTP server, DNS
server, domain, name, etc. on an IP phone manually or by using a router and/or a DHCP server to
automatically assign the IP address and other network information. For more information on how the
Auto IP Configuration and DHCPv6 settings determine where the IP Phone acquires its IPv6 address and
other network settings, see Table 4-5.

Device Configuration Menu
The Device Configuration menu provides access to eight sub-menus from which you can view a variety
of settings that are specified in the configuration file for a phone. (The phone downloads the
configuration file from the TFTP server.) These sub-menus are:
• Unified CM Configuration Menu, page 4-17
• SIP Configuration Menu for SIP Phones Only, page 4-18
• Call Preferences Menu for SIP Phones, page 4-20
• HTTP Configuration Menu, page 4-21
Table 4-5 Determining Where a Phone Acquires Its Network Settings
DHCPv6 Auto IP Configuration How the Phone Acquires its IP address and Network Settings
Disabled Disabled You must manually configure an IP address and the other network settings.
Note When DHCPv6 is disabled, the Auto IP Configuration setting is
ignored.
Disabled Enabled You must manually configure an IP address and the other network settings.
Note When DHCPv6 is disabled, the Auto IP Configuration setting is
ignored.
Enabled Disabled The DHCP server assigns the IP address and the other network settings to the
phone.
Enabled Enabled When the M-bit is set on the router, the O-bit is ignored. The phone can set
its IPv6 address based on an IPv6 address that it received from a DHCPv6
server or the phone can acquire its IPv6 address through stateless address
autoconfiguration.
When the M-bit is not set, you should set the O-bit on the router. The phone
will then acquire its IPv6 address through stateless address
autoconfiguration. It will not request an IPv6 address from the DHCPv6
server, but it will request other network configuration information.
