22.1 Setting the IP-interface parameters via DHCP
Default, the VoIP Gateway tries to configure via DHCP each time it is switched on. The
configuration mode without DHCP is activated however each time the reset button is
pressed (refer here to section
Setting the IP-interface parameters without DHCP
1
There are basically two ways of configuring an IP address for the VoIP Gateway;
automatic mode and client mode.
• When the VoIP Gateway is delivered from the factory, DHCP is in an automatic
mode. DHCP can also be forced into automatic mode by doing a factory reset
(
Generate the Default Configuration
• With a short reset the DHCP fixed mode is activated and the VoIP Gateway is
allocated the IP address 192.168.1.1.
• It is recommended to use the VoIP Gateway in DHCP client mode. To do this you
need a DHCP server in the network. Ask your network administrator to reserve a
fixed IP address for the VoIP Gateway via DHCP. Tell your administrator the
hardware address of the VoIP Gateway, see chapter
• If the power supply is interrupted while the VoIP Gateway is in automatic mode
the DHCP client mode will be activated. The VoIP Gateway will now be assigned
an IP address by the DHCP server in the network.
• You can display the allocated IP address as follows.
In
the command line, enter C:> plus the following command:
nbtstat –R
nbtstat –a IGWP-XX-XX-XX
Where the Xs should be replaced by the last 6 hexadecimal numerals from
the VoIP Gateway's MAC address.
2
Now start the web-based configuration, using the new IP address.
Proceed as follows:
3
C
onnect the Ethernet (ETHX) RJ 45-connector of the VoIP Gateway to the RJ 45-
connector of your Ethernet switch using a twisted pair cable.
4
Switch the VoIP Gateway off and then on again, to activate the DHCP client.
5
The VoIP Gateway will now be assigned an IP address. If your network administrator
has not set up a permanent IP address for you, you have to find out which IP
address has been assigned. There are two ways of doing this:
• The simplest option is to ask your network administrator.
• The other option is to consult the VoIP Gateway itself. Once the configuration
has been carried out successfully, the VoIP Gateway registers the NetBIOS name
“id- XX-XX-XX“, with id replaced by IGWP and "XX-XX-XX" replaced by the last
6 hexadecimal numerals from the serial number. See
Tip:
The most convenient way of configuring the IP interface parameters is via DHCP,
provided your network has a DHCP server.
