Network : DHCP page to “Static address assignment”.
Optionally, you can use the dynamic IP address assignment
from the DHCP server. For this, change the
Status setting on
the Network : DHCP page to “Dynamic address assignment”
and also change the Devices selection to the “All” setting or to
the “with configured MAC only” setting.

By using the “Easy Configuration / Hot-Desking” feature you
can add a device entry without entering a MAC address and
without entering an IP address. An unregistered
Forum IPhone 512 / Forum IPhone 545 will show a login page
after startup. A user can enter the desired call number and the
matching user PIN which will establish the association of the
user account to the device entry. For this, change the
Status
setting on the Network : DHCP page to “Dynamic address
assignment” and also change the Devices selection to the
“All” setting or to the “with configured MAC only and all SIP
system devices” setting.
If you want to use both features concurrently, change the Status
setting on the Network : DHCP page to “Dynamic and static
address assignment”.
If you operate another DHCP server in your network, the
Forum IPhone 512 / Forum IPhone 545 can distinguish the differ-
ent DHCP answers and will normally take its configuration data
from the Forum 523/524 communications system nevertheless. In
a conflict situation, you may need to prevent the configuration of
the Forum IPhone 512 / Forum IPhone 545 SIP phone by a for-
eign DHCP server. For example, add an exception rule for all MAC
addresses starting with 00:08:5D.
The TFTP server of the Forum 523/524 communications system
will serve up to 60 concurrent data transfers. To avoid overloading
the TFTP server (e.g. after a power failure), additional devices
may get an IP address from the DHCP server with a delay. The
allocation of IP addresses will restart if the TFTP server indicates
the end of the overload situation.
