Telephoning

Callback

If you call another subscriber of your Aastra 800 / OpenCom 100 communications

system and the line is busy, you can initiate automatic callback. Your user group must

have authorisation for this feature to be able to use it.

Answering a callback

A callback is carried out when the other subscriber is free.

Baby Call

The “Baby call” function dials a previously programmed internal or external call

number a specific time interval after pressing the call key (please refer to

page 124). The default time interval on the communications system is 5 seconds. The

system administrator can change this value. If you begin dialling a call number within

the specified time interval, the baby call is cancelled.
