Enterprises with small branch offices that implement a Cisco IP
NOTE
Telephony Voice over IP solution typically implement Cisco
CallManager at a central office to control Cisco IP Phones at small
branch offices. This implementation allows centralized call
processing, reduces the equipment required, and eliminates the
administration of additional Cisco CallManager and other servers at
branch offices. Cisco IP Phones download their configuration from a
TFTP server. When a Cisco IP Phone starts, if it does not have both the
IP address and TFTP server IP address pre-configured, it sends a
request with option 150 or 66 to the DHCP server to obtain this
information.
In the IPv6 Setting tab, specify the IPv6 addressing for the VLAN if you enable the
IIPv4/Pv6 mode.
• IPv6 Address: Enter the IPv6 address based on your network requirements.
