New features in release 2.6
On the IP Phone UI for 5-line phones, a User or Administrator can select Preferences-
>Time and Date->Time Zone and choose "DP-Dhcp" from the displayed time zone
list. On the IP Phone UI for 3-line phones, you select Preferences->Time and Date-
>Time Zone and enter "DP" for the country code, or press "*" and select "Dhcp" from
the displayed time zone list. If you enable DHCP Option 2 via the IP Phone UI, the
change takes place dynamically.
Notes:
• When DHCP Option 2 is enabled on the phone, the phone still uses the values set
at Preferences->Time and Date->Daylight Savings configuration settings to
control daylight savings time.
• The default behaviour for the phone is to use the NTP server from Option 42 (or
current configuration setting) and the current time zone settings.
• If the time zone name parameter is set to a value other than Dhcp, then DHCP
Option 2 is disabled.
Reference
For more information about using the "time zone name" parameter in the configura-
tion files, see the IP Phone Administrator Guide.
