Exchange Line Authorization
If you like to prevent high telephone charges due to calls to e.g. high
price service numbers, you can limit the dialling options for each individ-
ual internal telephone or for each group. You can configure with the con-
figuration program COMset exchange line authorizations (separate for
business and private calls) for each subscriber. These authorizations
are defining which type of numbers are allowed to be called by the sub-
scriber (all national and international numbers, national numbers only or
local calls only). A subscriber can also be limited to internal calls or
accepting external calls only. Blocking numbers are limiting an
exchange line authorization, Release numbers and Short-Code Dialling
authorization are extending a limited exchange line authorization.
These numbers can be modified with COMtools.
Call Allowance
If you like to have a fixed limit for call charges, you can configure a
defined amount of charge units for each subscriber. You can configure
with COMset, if the call allowance accounts are charged for all calls, pri-
vate calls, business calls, group calls (calls made as group member
logged in outgoing). The customer can modify the account for each sub-
scriber by telephone

The PBX has a permanent call charge data memory for 3000 data sets.
A call charge data set contains the following information:
Number of the call partner, if presented.
Exchange line and MSN used for the call.
Date and time at call beginning.
Call duration or ringing duration for unsuccessful calls.
Charge units and call cost sum.
Internal subscriber involved in the call.
Internal group involved in the call.
Type of call: Incoming or outgoing, business or private, successful
or unsuccessful.
Project number, if assigned to the call.
The bundled software for call charge data management COMlist and a
PC connected to the PBX lets you manage, analyse and transfer call
charge data from the PBX. It is also possible to print the data directly to
a printer attached to the serial port of the PBX.
In case of a call data memory overflow you can enable the recording of
additional calls by activating the setting Overwrite the memory auto-
matically in COMset. If this is not what you want, you have to delete the
call data memory via telephone in time before no new data can be
recorded anymore

this would be the case, a Special dial tone if usage of the call data
memory has exceeded % can be configured in COMset for certain
subscribers.
To avoid a fast filling of the memory (e.g. by unsuccessful calls), you
can configure in COMset which kind of calls should be recorded. The

To use the function „call allowance" without restrictions, you
will need the feature „Advice of charge during the call
(AOCD)" for your ISDN exchange line. With „Advice of charge
at the end of the call (AOCE)" the PBX can only find out at the end of
the call, if the call allowance has been exceeded.
Please note that some providers do not transmit call charges. If such a
provider is used to make a call, a configured call charge allowance can-
not work for the corresponding call. To avoid this, the provider numbers
should be entered as restricted numbers with COMtools telephone book
and be activated for each telephone via COMset.
Least Cost Routing
The PBX enables you to call easy and without prior thinking via the
cheapest available network provider. This is called automatic Least
Cost Routing. You have to configure several options with the PC soft-
ware Soft-LCR in order to use this feature.
You can enable this feature for each individual subscriber by telephone.
This configuration can also be done by each individual subscriber
(page 31 in the user
manual). If you enable the automatic LCR for a tel-
ephone, the PBX will search for each external call started by you the
cheapest provider. The provider will be dependent on the dialled
number, date and time. The provider code number will automatically be
dialled in front of the external number.
LCR does not work for a Call forwarding to external telephone
numbers.
Analyse Call Data with the PC Program COMlist
The PC program COMlist helps the customer to manage and analyse
the call data in the call data memory of the PBX. Installation and use of
the PC program are described in the
bundled Software on page 58 in the user
Call Data Management with external Programs
If you do not like to manage your call charge data with COMlist but like
to use your own software, you have to configure the operation mode of
the serial interface to „data exchange with external programs" and con-
nect your PC with the PBX
