Voicebox Queries
There are various ways of listening to
the messages in your voicebox:
■ via OpenVoice (from a telephone
that has not been assigned the
call number of your voicebox)
■ by calling the voicebox directly
(from a telephone whose call
number is assigned to your
voicebox)
■ by means of the additional
menu Voicebox in the Main
menu (see “Voicebox” Menu on
page 70).
Please note: For detailed informa-
tion on the utilisation and opera-
tion of the OpenVoice, please refer
to the add-on guide “OpenVoice 200
– The Voicemail System in the
OpenCom 100 Communications Sys-
tem”.
Ending a Call
Press A to end a call.
If the subscriber you are speaking to
ends the call, the busy tone for your
telephone is switched off after a few
seconds and you are again reacha-
ble. This also applies if you were con-
nected using your headset. The time
before the busy tone is switched off
in hands-free mode is configured by
the system administrator. All other
connections are ended after
20 seconds when the receiver is not
replaced.
Using Routes
to Make Calls

The OpenCom 100 establishes calls
to the desired subscribers either au-

OpenCom 100 and specifies how
each route is seized. In order to man-
ually seize a specific route for a call,
dial the routing code before dialling
the (internal or external) call
number. By making calls via specific
routes, you can, for example, contact
subscribers in the branches of a large
company network. It is also possible
to use a manually entered routing
