During the device's start procedure, the IP address is configured and the device
software is requested via the DHCP and TFTP network protocols.

9.5.2 VoIP System Telephone Configuration

The VoIP system telephones Aastra 6773ip (OpenPhone 73 IP) and Aastra 6775ip
(OpenPhone 75 IP) obtain the required IP address configuration and operating
software via the DHCP, BOOTP and TFTP IP protocols. After the power supply is
assured, the device's internal boot loader is started which controls the further start
procedure.
Standard operating procedure is to contact the OpenCom 100's DHCP server so
that the start procedure can be concluded without problems. To register a new
VoIP system telephone, proceed as follows:
1. Temporarily remove the VoIP system telephone's ethernet connection. Switch
on the VoIP system telephone's power supply. Note the MAC address shown in
the display, for instance "MAC: 00:30:42:00:00:00". Switch off the power supply.
2. In the Configurator, open the Telephony: Devices: VoIP Phones page. Click
on the New button.
3. Select the VoIP system telephone's Type and enter the previously noted MAC
address. Assign a Name and Phone No. Confirm with Apply.
4. Connect the ethernet connection with the VoIP system telephone's RJ45 con-
nector. Switch on the power supply. Verify the correct start procedure on the
display.

9.5.3 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":
