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
3.1.4.1
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.
3.1.4.2
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 stratum1 server, a stratum2 server or a
local LAN NTP server, that in turn synchronizes with stratum 1 or stratum 2 NTP
servers. 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.
3.1.5
Configuring the SMTP server.
DVX-1000 uses an Simple Mail Transfer Protocol (SMTP) server to send
notifications by email. The server IP address and port have to be configured
correctly for delivering mails. The default administrative user's email id will be
used as the sender's address for sending notification mails. The SMTP server has
to be an open relay mail server since DVX-1000 does not provide sender
authentication credentials.
3.1.6

The following options can be specified in this section.
RTP Port (Min & Max)
Operator Number
Operator Features
Operator User Group
