Description:
Configures the access URL of the AutoDST file (AutoDST.xml).
Example:
auto_dst.url = tftp://192.168.1.100/AutoDST.xml
During the auto provisioning process, the IP phone connects to the provisioning server
“192.168.1.100”, and downloads the AutoDST file “AutoDST.xml”. After update, you will find
a new time zone “Paradise” and updated DST of “Pakistan (Islamabad)” and “India
(Calcutta)" via web user interface: Settings->Time & Date->Time Zone.
Note: It works only if the value of the parameter "local_time.summer_time" is set to 2
