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 environ-
ments as an alternative to SIP proxy servers. They control data traffic through the fire-
wall.
Outbound proxy and STUN servers should not be used simultaneously.
See also: STUN and 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 com-
bination).
Port
Data is exchanged between two applications in a Network via a port.
Port forwarding
The Internet gateway (e.g., your router) forwards data packets from the Internet that
are directed to a certain Port to the port concerned. This allows servers in the LAN to
offer services on the Internet without you needing a public IP address.
Port number
Indicates a specific application of a Network subscriber. Depending on the setting in
the LAN, the port number is permanently assigned or it is assigned with each access.
The combination of IP address/Port number uniquely identifies the recipient or
sender of a data packet within a network.
