Using the callback facility

If an internal station which you have called is busy or there is no reply, you can place a request for callback. This also applies to external calls via ISDN switching centres. This saves you having to dial the number re- peatedly. You are then called back

•as soon as the other party terminates his call

•as soon as the other party makes a further call

•as soon as the other party checks his mailbox and responds to your callback request ￿ page 20.

You can only place one request for callback at a time.

If your telephone belongs to an ONS group (One Number Service ￿ page 46), please note the fol- lowing features:

Callback On Busy is indicated only on the busy telephone, not in the whole ONS group. Callback On No Reply is entered in the mailbox

￿page 20 for all internal system telephones in an ONS group.

Storing a callback request

Precondition: The station which you have called is busy or there is no reply.
