Telephoning Making External/Internal Calls
telephone is switched off after a few
seconds and you can be reached
again. This also applies if you were
connected to the other subscriber
via your headset (only on the
OpenPhone 27). The time frame af-
ter which the busy tone is switched
off is configured by the system ad-
ministrator. All other calls will be
ended after 20 seconds if the hand-
set is off-hook.

HZ (routing code, tel. no.)
Enquiry calls:
GRZ (routing code, tel. no.)
The OpenCom 100 establishes calls
to the desired subscribers either au-
tomatically or via specific routes.
Your system administrator config-
ures these routes in the
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) telephone
number. By making calls via specific
routes, you can e. g. contact sub-
scribers in the branches of a large
company network. It is also possible
to use a manually-entered routing
code to record your call-charge data
for external private and business
calls separately.
For information on the current
routes and their codes, please con-
tact your system administrator.
