Select the necessary settings for operating your phone in your local network
and to connect it to the Internet. For more detailed explanations of the individ-
ual components/terms, see the glossary (
u
Select DHCP if you want your phone to be assigned a dynamic IP address by
a DHCP server. No further settings are necessary for the local network.
u
Select Static IP if you would like to set up a static local IP address for your
phone. A static IP address is, for example, useful if port forwarding or a DMZ
is set up on the router for the phone.
IP Address
Enter an IP address for your phone. This IP address allows your phone to be
reached by other subscribers in your local network (e.g., PC).
The default setting is 172.23.56.253.
Please note the following:
– The IP address must be from the address block for private use that is used
in the router. This is generally in the range 192.168.0.1 –
192.168.255.254 with the subnet mask 255.255.255.0. The subnet
mask determines that the first three parts of the IP address must be iden-
tical for all subscribers in your LAN.
– The static IP address must not belong to the address block (IP pool range)
that is reserved for the DHCP server of the router. It must also not be used
by another device on the router.
If necessary, check the settings on the router.
Subnet Mask
Enter the subnet mask for your device's IP address. For addresses from the
address block 192.168.0.1 – 192.168.255.254, the subnet mask
255.255.255.0 is generally used. This is preconfigured when the phone is
supplied.
