Full DHCP mode 59
Configure the DHCP server to support Full DHCP mode
SIP IP Phone class identifier
A Nortel-SIP-Phone-aware DHCP server is needed for Full DHCP mode.
For Full DHCP mode, the DHCP server requires special configuration.
After the DHCP server is configured to recognize the IP Phone 1140E with
SIP Firmware as a unique IP Phone, the DHCP server can treat the IP
Phone 1140E differently than other DHCP IP Phones. An IP Phone-aware
DHCP server can automatically configure Nortel IP Phones by sending all
information that the IP Phone requires.
The IP Phone 1140E and the DHCP server communicate using a unique
class identifier. After the IP Phone 1140E first sends the DHCP DISCOVER,
it includes the Nortel-SIP-Phone-A ASCII string within the Vendor Class
Identifier (Option 60). The DHCP server recognizes this special Vendor
Class Identifier (Option 60) and sends back OFFER, which also includes the
same Vendor Class Identifier. This makes it possible to notify the IP Phone
1140E with SIP Firmware that the server is IP Phone-aware, and that it is
safe to accept the offer from the server.
Every Nortel IP Phone 1140E with SIP Firmware fills in the Vendor Class
ID option of the DHCPDISCOVER and DHCPREQUEST messages with
the null-terminated, ASCII-encoded string Nortel-SIP-Phone-A, where A
identifies the version number of the information format of the IP Phone.
The Class Identifier Nortel-SIP-Phone-A must be unique in the DHCP
server domain.
The unique DHCP configuration is required to allow the DHCP server to
respond with a unique Option 66 parameter to the IP Phone 1140E with
SIP Firmware.
Note: The DHCP standard defines Option 66 as the bootp server
address in a string. The meaning of the bootp server address is
extended in Nortel IP Phone 1140E with SIP Firmware to include the
provisioning server address. The string in the DHCP offer for Option 66
can be
• the numeric IP address or name of the TFTP server or the URI (if
FTP or HTTP protocol is used) of the provisioning server in the
form of
<protocol>://<provisioning server URL>
