No external Call possible
햲
If you only have this problem with some internal telephones, please
check the exchange line authorization for these subscribers (config-
uration program COMset).
햳
If you only have this problem with some internal telephones, please
check, if there is a call allowance configured for these subscribers
and if the account is empty.
햴
If this problem already happens with the first power-up, please
check whether the right kind of connection was configured for the
external S
0
ports and modify it if necessary.
햵
Please check the connection between the NT (NTBA or external S
0
bus) and the PBX.
햶
Disconnect the PBX from the external power supply (Pull the plug)
for 5 seconds or perform a reset (
). If the problem is solved,
the PBX or the telephone had a malfunction.
햷
You can check the function of the NT by directly connecting an
ISDN telephone (If you have a Point-to-point ISDN line, the tele-
phone must be compatible to the Point-to-point connection). If there
is still no telephoning possible, disconnect the NT from the external
power supply (Pull the plug) and the exchange line for 5 seconds.
If the problem is solved, the NT had a malfunction. If the problem
remains, contact your network provider for help.
Short-Code Dialling is not possible, external Calls are
possible
햲
Eventually no number is stored under the dialled short-code
number or the exchange line access number was added as a prefix.
The Telephone cannot be called
Check if your telephone is really not reachable. Try to make a call from
another internal telephone to your telephone.
No internal and external Calls
햲
Eventually a subscriber call forwarding has been configured for the
telephone. You can switch this function off, if unwanted.
햳

ephone. You can switch this function off, if unwanted.
햴
Disconnect the telephone from the PBX for 5 seconds and an even-
tually existing external power supply (Pull the plug). If the problem
is solved, the telephone had a malfunction.
햵
Please check if the ringer is deactivated or defective.
햶
Disconnect the PBX from the external power supply (Pull the plug)
for 5 seconds or perform a reset (
). If the problem is solved,
the PBX or the telephone had a malfunction.
No incoming external Calls, but Calls from internal
Telephones are possible
햲
Eventually a MSN/DDI call forwarding has been configured. You
can switch this function off, if unwanted.
햳
If you did not configure an external ringer rhythm with COMset for
the telephone, no external calls are possible.
햴
If you did not configure an (partial) exchange line access with COM-
set for the telephone, incoming external calls are not possible. Out-
going external calls are not possible either in this case.
햵
Please check the connection between the NT (NTBA or external S
0
bus) and the PBX.

No external Calls are reaching an internal Target Telephone
with a Call Forwarding activated
햲
If you did not configure an (partial) exchange line access with COM-
set for the target telephone, incoming external calls are not possi-
ble. Outgoing external calls are not possible either in this case.
No incoming Calls to the Group Number
햲
To receive calls to the group number, you have to log in as a group
member „incoming“.
햳
To be able to log into a group, your telephone has to be configured
as member of the group with COMset.
햴
Eventually a group call forwarding has been configured for the
group. You can switch this function off, if unwanted.
Query or Transfer not possible
Pressing the FLASH key disconnects the Caller
햲
The FLASH duration of the telephone is too long. Modify the set-
tings of the telephone (see manual of the telephone) or the settings
of the PBX with the function „learn flash time“ (see
Pressing the FLASH key leaves you in the first Call
햲
The FLASH duration of the telephone is too short. Modify the set-
tings of the telephone (see manual of the telephone) or the settings
of the PBX with the function „learn flash time“ (see
uration of analog Devices on page 18
).
햳
The FLASH-key of your telephone is configured as EARTH-key and
not as FLASH-key (see manual of the telephone).
ISDN Telephone is ringing after putting the Receiver on-
hook and you are reconnected
햲
Please check with the manual of your telephone, if „Transfers on a
PBX“ is activated. If not, try to correct this problem.
A Query is not possible via T-Net-Function Key/Menu
햲
Analog telephones equipped with T-Net-function keys or menus are
using a long FLASH (300 ms). Eventually your PBX is not confi-
gured for this FLASH timing. Most of the time an additional FLASH-
key is available at the telephone. Configure this key also for 300 ms
(see manual of the telephone) and let the PBX learn the FLASH tim-
ing (see
chapter Configuration of analog Devices on page 18
You try a Query from an external Call to an internal Call and
hear the busy Signal
햲
The called party is probably talking. Try again later.
햳
If you did not configure an (partial) exchange line access with COM-
set for the called telephone, a Query call from an external call would
not be possible.
