10.4.4 Start Procedure

It may sometimes be useful to understand a VoIP system telephone's start pro-
cedure. Examples:
■
A complex DHCP address assignment prevents the operation of the
OpenCom 510's DHCP server within the LAN.
■
A VoIP system should be operated with a non-broadcast-capable IP con-
nection. This may be an RAS connection, a VPN connection or another type of
routed connection.
An external DHCP server can also control a VoIP system telephone's start pro-
cedure. In this case, system software matching the type of VoIP system telephone
must be transferred via TFTP.
After the VoIP system telephone has been connected to the mains power supply,
the start procedure is as follows:
1. The boot loader starts and shows the VoIP system telephone's MAC address in
the display. A DHCP request is sent simultaneously via broadcast on the
255.255.255.255 broadcast address.
