IP handset
Introduction
The Thrane IP Handset communicates using
Internet Protocols (IP). The handset is not
strictly dedicated to the
SAILOR FleetBroadband system, but can
also be used in a public network as a
standard IP telephone.
The IP handset is powered directly from the
LAN interface using Power over Ethernet
(PoE).
When the IP handset is used with the terminal, it communicates using IP
between the handset and the terminal. However, on the BGAN network side of
the terminal, calls are transmitted as circuit-switched calls.
