7.4.4 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
Aastra 800’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.
The file name is determined by the telephone type.
