OTHER USEFUL FACILITIES

NETWORKING	Networking is the connection of several premises within a
	company. The connection can be set up via leased lines, public
	lines, Local Area Network (LAN) or Wide Area Network
	(WAN). Ask your system administrator about details regarding
	networking.
IP CALLS	IP calls are internal calls sent via an internal data network
	(LAN or WAN) and the transfer of data and voice is made on
	the same line. If you are connected to an internal data network
	the IP connection is made automatically. To minimise the
	traffic on the network the speech quality is decreased.
	If the speech quality is not acceptable you can disconnect the
	IP call and switch to a non-IP call (alternative network). The
	switch from the IP net to the non-IP net is made during the
	call, so the call does not have to be disconnected.
	If you want to switch to a non-IP net during the call:
	Press
	Dial
	During the procedure the other party is put on hold. When
	the procedure is ready you will receive a special ringing tone
	and the call is resumed in the non-IP net.
	Note: A switch to a non-IP call can only be performed if the
	original call is an IP call, otherwise you will receive a blocking
	tone.
