No external Calls are reaching an internal Target Telephone with a
Call Forwarding activated
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 also not possible in this case.
No incoming Calls to the Group Number
To receive calls to the group number, you have to log in as a group
member „incoming".
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
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".
Pressing the FLASH key leaves you in the first Call
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".
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
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
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.
You try a Query from an external Call to an internal Call and hear
the busy Signal
The called party is probably talking. Try again later.
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.
Pick-up is not possible
Busy Tone during Pickup for external Call
If you did not configure an (partial) exchange line access for busi-
ness calls with COMset for the telephone, a Pick-up of an external
call is not possible.
Busy Tone during Pickup on the internal S
Probably both voice channels of the internal S

Service Functions, Troubleshooting
Pick-up takes over ongoing Calls to another Telephone
The Takeover function and pick-up use the same functional proce-
dure. Switch off „conversation may be taken over" via configuration
program for all telephones. The permission for a Takeover is only
useful for answering machines.
You cannot identify Door Bell ringing
Door Bell rings with the Rhythm „1 x long"
Check whether the internal Call Forwarding from the Door Terminal
for the corresponding telephone is switched on.
Check whether the CLIP information with door terminal numbers
was switched on for the corresponding telephone.
PBX is not programmable
Busy Tone after entering the Password
Please check your password for correctness.
Programming with the PC is not possible
If you forgot your setting password that you need for the access with
the configuration program COMset, please contact the manufac-
turer.
If you have this problem on the internal S
restricted for PC programming. Try again on a different S
possible, or with the serial port. If necessary you can try to access
on all internal S
ports in a timeframe of 2 minutes after a PBX reset.

If you have this problem on the internal S
troller might eventually not present an MSN (as a workaround, you
can configure with COMset a subscriber as „ISDN PC-controller" on
the S
port). Try again on a different S
0
serial port.
If this problem occurred when remote programming via an internal
S
port, you probably forgot the exchange line access number when
0
entering the customer's telephone number.
If the other tips cannot help you, it is possible to initialize the PBX
with a push on a button. Hereby all settings will be resetted into the
default factory settings (administrator and subscriber password are
maintained). How these default factory settings and the internal tel-
ephone numbering plan look like in detail can be learned on
page
42. Do the following steps: Press the update key and keep it
pressed. Shortly after that additionally press the reset key – the
case LED glows red. Now keep the update key pressed as long as
the case LED starts glowing green.
You can not program with one Telephone
Eventually the configuration of some functions (Call forwarding,
remote switching, manual configuration switching) or all functions
are restricted for this telephone.
If you configured a programming telephone, administrator settings
(with secret password) would only be possible from that telephone.
