Consultation call
You are on a call. With a consultation call, you interrupt the conversation briefly to estab-
lish a second connection to another participant. If you end the connection to this partici-
pant immediately, then this was a consultation call. If you switch to and fro between the
first and second participants, it is called call swapping.

D
DHCP
Dynamic Host Configuration Protocol
Internet protocol that regulates the automatic assignment of IP addresses to network
subscribers. The protocol is made available in the network by a server. A DHCP server can,
for example, be a router.
The phone contains a DHCP client. A router that contains a DHCP server can assign the IP
addresses for the phone automatically from a defined address block. This dynamic assign-
ment means that several network subscribers can share one IP address, although they use
it alternately and not simultaneously.
With some routers you can specify that the IP address for the phone is never changed.
Displayed name
VoIP provider feature. You can specify any name that is to be shown to the other party dur-
ing a call instead of your phone number.
DMZ (Demilitarised Zone)
DMZ describes a part of a network that is outside the firewall.
A DMZ is set up, as it were, between a network you want to protect (e.g., a LAN) and a non-
secure network (e.g., the Internet). A DMZ permits unrestricted access from the Internet to
only one or a few network components, while the other network components remain
secure behind the firewall.
DNS
Domain Name System
Hierarchical system that permits the assignment of IP addresses to domain names that
are easier to remember. This assignment has to be managed by a local DNS server in each
(W)LAN. The local DNS server determines the IP address, if necessary by enquiring about
superordinate DNS servers and other local DNS servers on the Internet.
You can specify the IP address of the primary/secondary DNS server.
See also: DynDNS.
Domain name
Name of one (several) Web server(s) on the Internet (e.g., www.gigaset.com). The domain
name is assigned to the relevant IP address by DNS.
