COLP/COLR
Connected Line Identification Presentation/Restriction
Service characteristic of a VoIP connection for outgoing calls.
COLP displays the phone number accepting the call on the calling party's dis-
play unit.
The number of the party accepting the call is different to the dialled number,
e.g. if the call is forwarded or transferred.
The called party can use COLR (Connected Line Identification Restriction) to
prevent the number from appearing on the calling party's display.
Consultation call
You are on a call. With a consultation call, you interrupt the conversation briefly
to establish a second connection to another participant. If you terminate the
connection to this participant immediately, then this was a consultation call. If
you switch between the first and second participant, it is called Call swapping .

Call Waiting
See Call waiting .
D
DHCP
Dynamic Host Configuration Protocol
Internet protocol that handles the automatic assignment of IP addresses to
Network subscriber . 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. The dynamic assignment means that several Network subscribers can
share one IP address, although they can only use it alternatively and not simul-
taneously.
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 during 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.
