Busy-on-Busy
For an incoming call via an external telephone number the external call
distribution may include several telephones, e.g. because somebody
likes to be reachable at several places. But if this person has a call on
one of these telephones, the other telephones will also ring in case of a
new incoming call to the external telephone number. Then the caller will
think that nobody is there (at least when the call can not be taken by
another person because e.g. after hours only one person is in the
office). In order to avoid this situation, the function „Busy-on-Busy" can
be activated with COMset. The incoming caller gets the busy tone then.
Call Forwarding
If you assigned the corresponding authorization, a call forwarding can
be configured by each subscriber for his telephone
manual), for one of the groups
of the telephone numbers of the ISDN exchange line (MSN/DDI,
page 28 in the user
manual). A configuration of the Call forwarding in
COMset is also possible.
For each of these call forwarding settings the options „unconditional",
„on busy" and „on no Reply" are possible. Besides this one group can
be forwarded in case that all members are logged out (e.g. to an
answering machine). Internal as well as external forwarding targets are
possible.
In the default factory settings an external call forwarding is always exe-
cuted via 2nd B channel. So the PBX establishes a connection to the
external destination number automatically by using an additional free B-
channel in addition to the B-channel used by the incoming call. The
charges for the connection established by the PBX will be charged to
the PBX subscriber. If you like to avoid that any free B-channel is used
by the PBX (e.g. because the costs for the different S
different persons), you will be able to configure with the configuration
The following settings are recommended for the subscriber connection
of fax machines, FaxTAM, modem, ISDN PC-controller or answering
machines and can be configured in COMset:
Do-not-Disturb off,
Call Waiting off,
no charge impulse,
no group membership (besides of answering machine - group),
Door call distribution off (except answering machine with internal
call forwarding from door terminal),
Door opener authorization off,
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

program that the call forwarding will not use other exchange lines.
Please note that the possibility of a not successful CF will be higher
because of a busy B channel.
If you like to avoid the multiple usage of the B-channels, you can con-
figure the PBX to perform the MSN/DDI call forwarding always in the
public exchange instead of the 2nd B-channel. The programming with
the subscriber telephone will be the same. But you may experience a
longer configuration response time.
The delay time for a Call forwarding „if nobody takes the call" is adjust-
able in COMset (only if configured via the 2nd B channel).
For the Call forwarding „on busy" the fallback on busy be switched on
in COMset. If the busy subscriber hangs the receiver up, the already for-
warded call falls back to him again (if nobody has taken the call in the
meantime).
Do-not-Disturb
If you do not temporarily like to be disturbed by your telephone, you can
configure your telephone to prevent external and internal calls. The so-
called Call protection for internal and external calls can be switched on
in COMset or via telephone

If he likes to be reachable for certain persons with the activated „do-not-
disturb", it will be possible to enter their external telephone number into
a VIP list with the PC software COMtools.
If you do not like to be called by certain persons, you are able to enter
their external telephone numbers into the Robinson list with the PC soft-
ware COMtools.
Then the lists can be activated or deactivated in COMset or via tele-
phone
(page 30 in the user
manual). It is necessary for the PBX to iden-
tify the caller: The caller has to present his telephone number.
The call protection is only valid for calls directed to the own telephone.
In order not to get group calls, the user has to „log out". Exception: The
Robinson list can also be activated for groups with COMset.

Analog telephones that execute certain function via T-Net
