Glossary
Terminology
F
Remote Extension
A remote extension is an internal subscriber (e.g., home office, outlying parts of the building,
branch offices) that is connected to a central telephone system via a public network (e.g., the
Internet). In this case, the distance between the telephone system and the outlying extension
is not relevant.
F
Firmware
Firmware is the operating software on the telephone or PBX that is stored in the device itself.
The device cannot function without firmware.
G
Gateway
A gateway is a PC or router that is used as an intermediary between two (different) networks.
The Internet service provider is the gateway for direct Internet dial-up connections. If you use
a router, this is the gateway in a local network.
H
Hands-free Calling
During hands-free calling, the loudspeaker and microphone on the device are switched on. This
option allows you to talk on the telephone even if you have no hands free. In addition, other
people in the room can participate in the call.
