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 Router 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 PCs that are connected to each other in a network e.g., servers, PCs and
phones.
O
Outbound proxy
Alternative NAT control mechanism to STUN and ALG.
Outbound proxies are implemented by the VoIP provider in firewall/NAT
environments as an alternative to SIP proxy servers. They control data traffic through
the firewall.
Outbound proxy and STUN servers should not be used simultaneously.
See also: STUNand NAT.
P
Paging (handset search)
Base function for locating the registered handsets. The base establishes a connection
to every registered handset. The handsets start to ring.
PIN
Personal Identification Number
Protects against unauthorised use. When the PIN is activated, a number combination
has to be entered to access a protected area.
You can protect your base configuration data with a system PIN (4-digit number
combination).
