LAN DHCP Server
If the LAN already uses a DHCP server to configure workstation computers,
there are various options for correctly responding to VoIP system telephones’
DHCP, BOOTP and TFTP requests. A comparatively simple approach is
described here.
1.
Configure the LAN’s DHCP server to ignore DHCP requests from the VoIP
system telephones. With a Linux DHCP server programme, you must, for
example, include the following lines in the system file “/etc/dhcpd.conf”:
group {
deny booting;
host 192.168.11.12 {
hardware ethernet
00:30:42:00:11:22;
}
}
Every DHCP service programme has similar options. You may need to
reserve a free IP address for each VoIP system telephone. You will find
more details in your DHCP service programme’s online help or handbook.
The MAC address of all VoIP system telephones always begins with
00:30:42.
2.

this, call up the
Configurator

Network: DHCP
page. Click on
the
Change
button.
