Least Cost Routing (LCR)
For every outgoing external connection, the communications system automati-
cally makes a connection – via LCR – to a network operator defined by the system
administrator. If you do not use this preferred connection and for a single call
would like to select a network operator yourself (call by call), switch LCR off before
making the call (please refer to the “LCR off” menu entry in the Menu when Pre-
dialling starting on page 55 section).
Note
The baby call and external call forwarding are not automatically conducted via
preferred connections. This is where you can prefix the codes of the desired
network operator when entering the call number, when you wish to use a
different network operator than the standard one.
Calls in the Call-Waiting Queue
The system administrator can additionally configure and activate a Call-waiting
queue for your telephone in the Aastra 800 / OpenCom 100. While you are making
a call, new calls are registered in this queue, the caller first hears an announcement
(if your system administrator has configured an announcement) and then the ring
tone. The number of calls that can be registered in your queue is defined by the
system administrator, e.g. 5 calls. Once this number is reached, any additional
callers hear a busy signal. The calls in the queue are transferred in accordance with
their priority (baby calls, door calls, VIP calls, other internal and external calls), calls
with the same priority are transferred in the order made.
Calls that are in the queue for too long a time are removed. The caller then hears a
busy signal also. The time interval until an external call is cleared from the queue is
defined by the network operator. This is usually 2 minutes in Germany and in other
European countries usually 3 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 activated on your telephone, every time a new call
comes in you will hear the call-waiting tone and see on your display whether the
call is external or internal. If call-waiting protection is activated and you end the
call, the next waiting call will be signalled.
For more information please refer to the “Call Queue” chapter in the
“OpenCom 100 Mounting and Commissioning” or “Aastra 800 Installing and
Commissioning” user guide.
