System
DHCP server
The PABX has an integrated DHCP server, which is enabled on delivery and has an address range
appropriate for the network mask set. If you want to use another DHCP server in your network,
you must disable the one in the PABX. Running two DHCP servers in parallel in a network is not
permitted.

DNS Server
(optional)
IP address of the DNS server
The DNS (Domain Name System) allows you to assign IP addresses to symbolic
names. The DNS server is required to convert the DNS name into the IP address
when a connection is being established to a server.
By default, the router/gateway's IP address is used here. This forwards PABX
address queries to its DNS server.
You can enter the IP address of an alternative DNS server in the second field
DNS Server (optional)
. This is used when the first DNS server cannot be
reached.
NTP Server
(optional) IP
IP address of the time server (NTP = Network Time Protocol). NTP ensures reli-
able time information across a network.
You can enter the IP address of an alternative time server in the second field
NTP Server (optional) IP
. This is used when the first time server cannot be
reached.
Host name
Host name for the PABX
Domain name
