Using Options 159 and 160 on the IP Phone
In addition to DHCP options 43 and 66 already supported on the IP Phones, the phones also support DHCP Options 159
and 160. The IP Phones use the following order of precedence when deriving the configuration server parameters: 43,
160, 159, 66.
In addition, an administrator can override this order of precedence by setting a configuration parameter called,
dhcp
config option override
(configuration files),
DHCP Download Options
(Aastra Web UI), or
Download Options
(IP
Phone UI). Setting this parameter results in the phone only using the chosen DHCP option and ignoring the other
options.
For more information about setting DHCP download preference, see
“Configuration Server Download Precedence”
