u Lift the handset.

Make an internal or external call to reach the desired device.

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 minimize 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:

Inquiry

Ô Press.

*61* 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.
