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 13).
You can only place one request for callback at a time.
Storing a callback request
