Passwords
By using secret passwords you can prevent unauthorized persons from
programming your PBX. The passwords pre-configured in the default
setting of COMset (Public, Secret, Remote) have to be changed. For
the password protected separation of private calls a private password
can be set for each telephone in COMset.
Your configuration made with COMset can be protected with a admin-
istrator password against unauthorized intervention. The configuration
cannot be changed without knowledge of the password.
The data edited with COMtools can be protected with the user password
by the administrator of the PBX. This password will absolutely be nec-
essary for reading out the call data with COMlist. The user password
has to set in COMset first, but it can be changed later in COMtools or
COMlist also.
Exchange line to Exchange Line Transfer
Each subscriber who makes external calls, can transfer/forward a call
between two external subscribers. To prevent this happens by mistake
(the forwarding person will be charged with the costs for the call at the
end), you can withdraw the authorization for the Exchange line to
Exchange Line Transfer from a subscriber in COMset. If you want to
perform an Exchange line to Exchange Line Transfer without this
authorization, the user has to start the second call with a special access
code (
). The transferred call is limited to the
maximum Exchange line to Exchange Line Transfer Time configured
in COMset.
Blocking Numbers
The Blocking numbers cannot only be used to prevent the dialling of
certain numbers on telephones, but they also offer a reliable protection
against dialling of so-called 0190 dialer programs that enforce the dial-
up into the Internet via expensive telephone numbers (e.g. 019x or
0900x).
The Blocking numbers have to be entered with COMtools telephone
book into the PBX and additionally in COMset the activation of the
Blocking numbers for the ISDN PC-controllers has to be done on the
internal S
0
and USB ports.
If the PBX was configured incompletely or wrong, 0190 dialers may per-
haps avoid the Blocking numbers. Therefore please pay attention to the
following points when configuring your PBX and ISDN PC-controllers:
왎
On each internal S
0
port with an ISDN PC-controller there are
always two internal telephone numbers configured as „ISDN PC-
controller“. For these two telephone numbers the Blocking numbers
have to be activated. This is necessary because there are dialers
trying to build up a channel-bundled connection or one of both inter-
nal telephone numbers is already in use and the dialer will take
automatically the second internal telephone number then.
왎
If the ISDN PC-controller has the option, assign an internal tele-
phone number to it. This number has to be configured for the corre-
sponding internal S
0
port as „ISDN PC-controller“ first.
In general there is no 100 per cent protection against
malicious use of PBX functions. Please pay attention that
a protection against malicious use can only be guaran-
teed if you have defined a administrator and user password in the
PBX.
... if you do not allow the access to the PBX and its programming.
... if you use the available authorizations with care (authorization
for the programming via the internal S
0
port, programming author-
ization, exchange line authorization, Blocking numbers etc.).
A responsible use of passwords is absolutely necessary for the
protection against malicious use.
Further advice for the protection against malicious use can be
found in the report of the Bundesamtes für Sicherheit in der Infor-
mationstechnik: „Sicherer Einsatz von digitalen Telekommunikati-
onsanlagen“ on the Internet at http://www.bsi.de/literat/tkanlage/
6001.htm.
In addition to the functions that protect against unauthorized program-
ming, telephoning and transfers, the PBX has several other security
functions.
Emergency Short-Code Dialling and Priority Func-
tion
Emergency has priority (emergency priority circuit) is switched on in
COMset and makes a public exchange line available at any time when
dialling a emergency short-code dial number or when tripping an alarm.
If all lines are busy, an existing call will be terminated for the emergency
call. The Emergency short-code dial numbers can be entered into
the short-code dialling memory by the administrator with COMtools tel-
ephone book or via telephone (
Alarm Functions
If your PBX is equipped with a door/switch module, and the alarm input
on the module (unused door bell button input) is properly connected
(e.g. to the output of an alarm system), you can also use the alarm func-
tions (
).
Automatic Dialling (Baby Call)
With the automatic dialling function (baby call) you can configure your
telephone to dial automatically an internal or external number. This may
be configured with COMset or by each subscriber with his telephone
(
Room Monitoring
A room can acoustically be monitored from internal or external callers if
room monitoring has been enabled for a telephone in the room
(
). It is only possible for one telephone at the
same time. For the external room monitoring the remote programming
and switching MSN/DDI as well as the Remote password have to be
configured in COMset.
