DHCP (Dynamic Host Configuration Protocol) assigns IP addresses to telephones, and can
provide other information to the phones, such as server addresses. When using DHCP,
phones do not need to be configured with static IP addresses.
The DHCP server can supply:
•
Phone IP Address
•
Phone Subnet Mask
•
Domain Name
•
Default Gateway IP Address (Router)
•
DNS Server(s) IP Address
•
NTP Server(s) IP Address (Time Server)
•
Update Server IP Address (Boot Server Host Name) and protocol
•
SIP Proxy IP Address
•
VLAN Configuration
Settings not supplied by DHCP must be entered locally at the phone, or in a configuration
file which is supplied to the phone via an update server .

The DHCP server requires a scope of IP addresses that can be assigned to the phones. The
scope must be configured with the router address, vendor-specific info, and the update
server address.
You can use an existing DHCP server for assigning IP addresses to the telephones, or add a
new server.
S S c c o o p p e e
Select the DHCP server that you will use for assigning IP addresses to telephones.
Add a new scope, and then enter the following:
•
A name and description for the scope.
•
The start and end of the IP address range that can be assigned to telephones. Do not
include telephones and computers in the same address range.
•
Any IP addresses that will be excluded from the address range.
•
The lease duration for telephone IP addresses. A lease duration of seven days or
longer is recommended.
