Least Cost Routing (LCR)
For every outgoing external connection, the communications system automatically
makes a connection – via LCR – to a network operator defined by the system adminis-
trator. 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 69 section).
Note
The baby call and external call forwarding are not automatically conducted via pre-
ferred connections. This is where you can prefix the codes of the desired network op-
erator when entering the call number, when you wish to use a different network op-
erator 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.
