DHCP server

Data from DHCP
The phone has support for DHCP by which the following IP configuration
data can be provided:
• Own IP address, subnet mask and default gateway, received in the
DHCP standard fields (1 and 3).
• The VLAN used for the phone can generally be set in option 132 or
be part of Option 43. If the phone's configuration has another value
than that of the option value it will configure according to the Option
132 value and making a reboot.
• IP address to the software server. The path to the firmware to be
downloaded from the software server can also be provided as well
as the protocol to be used. The recommendation is to use DHCP
option 66 (TFTP server name), but DHCP option 60 (vendor class
identifier) and option 43 (vendor specific information field) can also
be used.
The following examples show the different possibilities on how to use
option 66,160 or 159 in order to get the IP address or host and its path
to the software server. For http and https it is possible to define the port.
Default port for http is 80 and default port for https is 443:
http://192.168.1.45
http://192.168.1.45/path
http://192.168.1.45:8080/path
http://srv.example.com/path
The default dhcp precedence order is 43, 160, 159, 66. So if the phone
receives the software server configuration in both option 66 and option
43, then option 43 takes precedence over option 66.
If option 66 is already in use, it is possible to set the configuration server
in either option 160 or 159 instead.
DHCP Settings for Option 66
