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 Aastra 673xi/675xi 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 con-
figured 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 Aastra 673xi/675xi can
distinguish the different DHCP answers and will normally take its configuration
data from the OpenCom 100 communications system nevertheless. In a conflict
situation, you may need to prevent the configuration of the Aastra 673xi/675xi SIP
phone by a foreign DHCP server. For example, add an exception rule for all MAC
addresses starting with 00:08:5D.
The TFTP server of the OpenCom 100 communications system will serve up to 4
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.

The Aastra 673xi/675xi SIP phones support the "Easy Configuration / Hot desking"
feature. This feature allows a user to operate his personal configuration on any
desired Aastra 673xi/675xi of equal type.
To prepare a Aastra 673xi/675xi for Hot Desking, you can configure a function key
with the "Logout" function. If this function key is pressed, the currently assigned
device entry will be marked as "Logged Out" and the Aastra 673xi/675xi restarts.
You can indicate logged out device entries in the Configurator on the Telephony:
Devices: VoIP Phone page by their shortened MAC address.
