Using callback
You can request a callback if the internal station called is busy or if no-
body answers. This also applies for external calls via ISDN exchang-
es. This feature saves you from having to make repeated attempts to
reach the user.
You receive a callback
• When the other party is no longer busy,
• When the user who did not answer has conducted another call.
