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 (Mitel 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
Download Precedence"
Note: Administrators should review the updated IP phone DHCP option precedence
order and configuration options to avoid potential impact to existing Mitel IP phone
deployments.
