Telephoning
Calls in the Call-waiting Queue
The system administrator can configure and activate a call-waiting queue especially
for your telephone in the OpenCom 100 / Aastra 800 system. While you are making a
call, new calls can be queued. These callers first hear an announcement (if the system
administrator has preset an announcement) and then the ring tone. The number of
calls permitted in the call-waiting queue is set by the system administrator during
system configuration, 5 calls for example. When this number is reached, further
callers hear the busy tone. The calls in the queue are put through in order of priority
(baby calls, door calls, VIP calls, other internal and external calls), irrespective of the
order in which they came in.
Calls that have been in the queue for too long are removed, and the callers then hear
the busy tone. The period of time until a call is released is set by the network operator.
In Germany this is usually two minutes and in other European countries usually three
minutes.
Your telephone can have a call-waiting queue even if it belongs to a subscriber group.
A call-waiting queue simultaneously affects call forwarding.
Note
If call-waiting protection is deactivated on your telephone, you will hear the call-
waiting tone every time a new call comes in. The display indicates if it is an internal
or an external call. If call-waiting protection is deactivated and you end the call, the
next waiting call will be signalled.
For more information please refer to the chapter entitled "Call Queue" in the
"Mounting and Commissioning" (with an Aastra 800: "Installing and Commissioning")
guide.
Forwarding Calls
Types of forwarding
You can forward internal or external calls intended for yourself to another internal call
number or, provided that you have the necessary user group authorisation, to another
external call number. Calls can be forwarded either immediately, after a specified
period of time (delay) or if the line is busy. You can configure more than one call for-
warding mode at the same time (Immediately, After delay or Busy). You can, for
example, configure call forwarding Immediately for external calls to one call number,
and call forwarding After delay for internal calls to a different call number. During
