Initiating Priority Call for Do-Not-Disturb
If you pick up the receiver, the subscriber will be called.
Note: A callback will be stored in the central office for a duration of up to 45
minutes. If the called subscriber has not terminated his call until then, the
callback will automatically be deleted.
Important: To use this function at ISDN telephones and system telephones
or to delete it again, this function must be supported via a function key or via
the menu by the respective telephone (see manual for the telephone).
Initiating Priority Call for Do-Not-Disturb
If the internal telephone you are trying to call is busy because it is set to do-not-disturb, proceed
as described in the following.
• Wait ten seconds.
The subscriber is now called.
Terminating a Query Call
If you make a query call and the number is busy but there is no response, proceed as described
in one of the following steps.
• The subscriber called for the query call does not respond: Press the Flash key (when
using a telephone with DTMF dialling) or the Query key (when using an ISDN
telephone) and dial 1.
You are now reconnected with the person waiting on the other line.
• The subscriber called for the query call is busy. Wait.
You will automatically be reconnected with the communication partner waiting on the
other line.
Note: On ISDN phones and system phones, this function – if available – is
performed via an existing function key or via the menu (see manual for the
telephone).
