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 server s. They control data traffic through the firewall.
Outbound proxy and STUN servers should not be used simultaneously.

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).
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.
