2 Getting started
To Set IP address through WEB, open the web browser and type in the default ip address of
the board. The initial login page will appear. You will have to log in as administrator to set
the system parameters. The default administrator user name and password is ‘ippbx’ and
‘ippbx’.
1. Connect power supply to the DVX-1000 and power up.
2. Connect the LAN port to the HUB/Local Network
3. The power indicator and LAN indicator should be ON, if the corresponding
LAN Port is connected to a Local Network.
4. DVX-1000 comes with the default ip address of 10.0.0.1. You can change
the ip address through CLI (Command Line Interface) or web interface.
3 Configuring system parameters
DVX-1000 can be configured through the following interfaces
•The web interface
•Command Line Interface (CLI)
The following section provides details regarding how the DVX system can be
configured through these interfaces. System configuration and call
monitoring are solely the privileges of users configured as
administrators. DVX-1000 ships with a single administrator already configured
(for security re sons, we recommend ch nging the def ult dministr tor p ssword) . Regular users
are allowed to configure only their individual features.

3.1 Using the web interface to configure the system
The DVX-1000 web interface can be accessed from any web browser supporting
frames and java script. Internet explorer (Version 4.0 and above) is the preferred
browser. The web interface can be accessed using the URL http://IPADDRESS ,
where IPADDRESS is the address assigned to the DVX-1000 board. The system
configuration page can be accessed by clicking the system configuration link from
the DVX-1000 web interface.
3.1.1 DVX WEB Requirements
The following browsers have been tested to be fully compatible with the DVX-
1000 web interface:
oInternet Explorer (Version 5.5 and above)
oNetscape (Version 7.0 and above)
oMozilla ( Version 5.0 and above)
oGaleon (Version 7.0 and above).
3.1.2 Configuring the IP
IP configuration for the DVX-1000 board can be static or through DHCP. The
default factory setting for IP is 10.0.0.1. To bring the board up for the first time;
configure an IP for the board from the CLI interface. Subsequently, all
configurations can be done through the web interface by accessing the board’s
configured IP .
3.1.2.1 Configuring the IP address automatically using DHCP
DVX-1000 can be configured to get it’s IP through Dynamic Host Configuration
Protocol (DHCP). To enable this, select DHCP and click on Apply. Please note
that on some browsers, redirection to the new IP is not possible. In this
case, the new IP has to be ascertained from the CLI interface and the
corresponding web page should be accessed.
3.1.2.2 Configuring the IP address manually.
Assigning a static IP for the DVX-1000 is the recommended method for IP
configuration as it is advisable to have the call server work on a fixed IP address.
To configure a static IP for DVX-1000, click on the system configuration link.
Now, under IP configuration, select static and enter a static IP, subnet mask and
gateway. Click ‘Apply’. Please note that on some browsers, redirection to
the new IP is not possible. In this case simply access the new static IP that
you have now configured for the board from the web.
Note: If you configure the IPPBX for HCP and you do not have a HCP server that has a
HCP clients list you may not be able to find the IP address of the device. It is
recommended to use a static IP address on the IPPBX so you will always know the address
of the unit.
3.1.3 Configuring the DNS server address.
DVX-1000 has a Domain Name Service (DNS) client built in that will resolve
hostnames accessing the DNS server that is configured. To set the DNS server
that is relevant to your network, access the system configuration page; modify
the primary and secondary DNS servers and click apply.
3.1.4 Setting the system time.
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

DVX-1000 User Manual
D-Link Confidential 10
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: aylight savings time is automatically supported by VX-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 Setting other configurable parameters
The following options can be specified in this section.
RTP Port (Min & Max) The minimum and maximum ports that DVX-1000 uses
for its media. Changing this also modifies the firewall
settings to block ports other than the ones configured.
Detailed configuration for the port range can be done by
clicking on ‘Advanced’ the ports that are used for
normal calls and those used for calls across NAT devices
can be minutely controlled here.
Operator Number The operator’s extension that will be contacted if the
call through the automated attendant fails, or if the
caller dials an invalid extension or no extension at all.
Operator Features Call feature preferences for the operator can be
configured by clicking on the ‘Features’ hyperlink
Operator User Group User Group of the operator.
Operator Route Group Route group to which the operator belongs
3.2 Configuring the system through the Command Line Interface
This section describes the DVX-1000 system configuration through the command
line interface. To access the command line interface, connect the console port of

commands. Once the user name and password verification succeeds, the DVX
command prompt will now appear and the user can now configure the system
with the aid of the CLI commands described below.

Call Server -> Configuration. To change the configuration, click on Edit. The
following configuration options can be changed.
Domain Specifies the SIP domain that this
server manages. This will be used in all
the SIP addresses on this server.
Port Specifies the UDP port number on
which call server would listen for SIP
messages. Some ports are internally
used by the call server, auto
attendant and media server and
are reserved. If the port specified
here conflicts with one of the reserved
ports, an error message will be
displayed.
Default

Specifies the default authentication
scheme that will be used to
authenticate SIP user. Note that the
authentication scheme is configurable
per user (during user configuration).

Time
Specifies the minimum expiry time the
server would accept for SIP

with smaller expiry time will be
rejected with a 423 (Interval too brief).
The minimum expiry time has to be
between 30 and 3600 secs.
SIP Configuration

Static NAT The public IP
specified will be
used in all
messages and one

the public IP to the
local IP of the
device will be
assumed. This

when there is only
one device behind
the NAT device and
one to one mapping
is specified between
the public IP of the
NAT device and the
local IP address of
the DVX.
