Time Configuration

DVX-1000 can either be configured to get its time through manual configuration or through Network Time Protocol
(NTP). It ships with a factory default setting of 1st of January 2005 10.10 a.m. A large fraction of the call server data
is dependent on the system time. This data includes registrations, feature time settings and call detail records (CDR)
amongst others. Changing the time configuration has to be done with a lot of caution. Changing the time to a time
prior to the current time would be a malicious attempt to invalidate the call detail records and extend registrations. The
administrator should be wary of this. Changing the time to one in the future should be done taking into account the
fact that current registrations may expire at the new time specified and hence phones may have to re-register to get
the calls started.
Setting the system time manually
In order to set the time manually, access the system configuration page. Under time configuration, choose manual and
modify the time to the required value. Now click apply. The time should now be set to the new one.
Automatically configuring the system time using NTP
DVX-1000 can synchronize its system time with an NTP server that has been configured. This server could either be a
local LAN NTP server, that in turn synchronizes with a stratum 1 or stratum 2 NTP server, or directly a stratum1 or 2 NTP
server that is relevant to your network. Access the system configuration page, under time configuration, choose NTP
and specify the primary and secondary NTP servers. Select the appropriate time zone. Click Apply. The NTP servers
will be tried for a predefined number of times and if these attempts fail, the present system time will be retained.
Note: Daylight savings time is automatically supported by DVX-1000 provided the system is configured to get the time
from an NTP server and the correct time zone is selected.
