P
Paging (handset search)
A base station function to locate registered handsets. The base station estab-
lishes a connection to every registered handset. The handsets start to ring.
Paging is activated by briefly pressing the button on the base station and is
deactivated by briefly pressing the same button again.
PIN
Personal Identification Number
Protects against unauthorized use. When the PIN is activated, a number combi-
nation has to be entered to access a protected area.
You can protect your base station configuration data with a system PIN (4-digit
number combination).
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 Inter-
net
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 set-
ting in the
LAN, the port number is permanently assigned or else it is newly
assigned with each access.
The combination of
IP address/Port number uniquely identifies the recipient
or sender of a data packet within a network.

Protocol Describes the agreements for communicating within a Network. It contains
rules for opening, administering and closing a connection, about data formats,
time frames and possible error handling.
Proxy/Proxy server
Computer program that controls the exchange of data between Client and
Server in computer networks. If the phone sends a query to the VoIP server, the
proxy acts as a server towards the phone and as a client towards the server.
A proxy is addressed via
Domain names/IP addresses and Ports.
Public IP address
The public IP address is the address for a network component on the Internet.
It is assigned by the Internet Service Provider. Devices that act as a link from a
local network to the Internet (gateway, router) have a public and a local IP
address.
