Start Procedure
It may sometimes be useful to understand a VoIP system telephone’s start procedure. Examples:
■
A complex DHCP address assignment prevents the operation of the Comfort Pro S’s DHCP server within
the LAN.
■
A VoIP system should be operated with a non-broadcast-capable IP connection. This may be an RAS con-
nection, a VPN connection or another type of routed connection.
An external DHCP server can also control a VoIP system telephone’s start procedure. In this case, system
software matching the type of VoIP system telephone must be transferred via TFTP.
The file name is determined by the telephone type.
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.
2. An IP address, network mask and the default gateway for the start procedure are sent from the DHCP
server. Via the “Next server” option, the DHCP server also provides the TFTP server’s IP address and the
operations software’s file name. The DHCP server uses the MAC address to select the operations
software file which matches the type of device.
