Basic Functions

Calls in the Call-Waiting Queue

The system administrator can additionally configure and activate a Call-waiting

queue for your telephone in the OpenCom 100 / Aastra 800. 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).

Calls with Booking Numbers

By means of a booking number you can record the call data of a connection to an

external subscriber and save them in the OpenCom 100 / Aastra 800 for further

evaluation. Booking numbers are useful, e.g. for calculating costs per client (fees

and times) in an office. Incoming calls can also be associated with a booking

number.

Notes on booking numbers

■ The system administrator defines the length of the entered booking number

during system configuration.
