can be uniquely identified worldwide. It consists of six parts (hexadecimal numbers)
separated by a "-" (e.g. 00-90-65-44-00-3A).

Music that is played while you are on a Consultation call or during Call swapping. The

N
NAT
Network Address Translation
Method for converting (private) IP addresses to one or more (public) IP addresses. NAT
enables the IP addresses of Network subscribers (e.g. VoIP telephones) in a LAN to be
concealed behind a shared IP address for the Routers on the Internet.
VoIP telephones behind a NAT router cannot be reached by VoIP servers (on account of the
private IP address). To "get around" NAT, it is possible to use either ALG in the router, STUN in
the VoIP telephone, or for the VoIP provider to use an Outbound Proxy.
If an outbound proxy is made available, you must allow for this in the VoIP settings for your
phone.
Network
Group of devices. Devices can be connected in either wired or wireless mode.
Networks can also differ in range and structure:
-Range: Local networks (LAN) or wide-area networks (WAN)
-Structure: Infrastructure network or ad-hoc network
Network subscriber
Devices and computers that are connected to each other in a network e.g. servers, PCs and
phones.
