Using the callback function

I f the telephone that you have called is busy or there is no answer, you can request a callback. This also applies to external calls via ISDN switching centres. This saves your having to dial the number repeatedly.

You are then called back

•as soon as the other party terminates his or her call, or

•as soon as the other party checks his or her mailbox and responds to your callback requestÆ page 28.

Storing a callback request
