Frequently Asked Questions

It is not possible to make external calls with one of the telephones.
Check whether a user is configured for the telephone. Otherwise the settings of the
Guests user group are valid for the telephone. To standard, this user group has no
external call authorisation.
Make sure the user configured for this telephone belongs to a user group with
external line access (
Configurator , User Manager: User groups menu).
Check also whether the internal call number of this telephone has been configured
for incoming call distribution (
Configurator , Telephony: Call Distribution menu).
One of the features (e.g. call diversion) on one of the telephones cannot be used
even though the feature has been configured in the Configurator of the
OpenCom 100.
Make sure the user configured for this telephone belongs to a user group that has
access to this feature (
Configurator , User Manager: User and User groups menus).
Some features cannot be used until the system PIN is changed.
Nothing is indicated on the display of one of the connected ISDN telephones.
You have connected the ISDN telephone to an external S
0
port (RJ-45 socket). These
ports are intended for connection to the NTBA only. Connect the telephone to an
internal S
0
port (pressure terminal).
Calls can be made but not received with one of the ISDN telephones.
The internal call number that has been configured for this ISDN telephone in the Con-
figurator ( Telephony: Ports: S0 menu) must also be configured as an MSN on the
ISDN telephone itself. For further information, refer to the User Guide of your ISDN tel-
ephone.
An ISDN telephone always rings, if another telephone on the S
0
bus is being
called.
This case also requires configuring the MSN on the ISDN telephone (see above
answer).
It is not possible to configure Call Distribution: Outgoing for multi-terminal
access.
You have configured multi-terminal access and system access in parallel. All outgoing
calls are therefore established via system access, and outgoing call distribution can be
configured for system access only in the
Configurator ( Telephony: Call Distribution
menu).
A specific MSN can be seized for individual calls by means of a code number pro-
cedure. For further information, refer to the “OpenCom 100 / Aastra 800 – Operation
on Standard Terminals User Guide” user guide.
