React to an incoming Call while Knocking

If you hear a tone that repeats itself again and again - the knocking
tone - during a call, an external subscriber is trying to reach you or
you are getting a door or alarm call. The external subscriber hears the
ringing tone.
Accept the knocking call: To talk to the knocking caller there are
two options. First: You take the knocking caller and finish the current
call at the same time. Second: You start a second call (query) with the
knocking person. Then the current call partner is held in the back-
ground. The options you have later can be learned in the
.
Refuse waiting caller: If you do not like to talk to the waiting caller,
you are able to ignore the waiting call or to refuse it by dialling a
sequence of digits. The waiting caller will hear the busy tone then (if
no other telephones ring).
Important: Incoming calls are only signalled, if the function Knock-
ing/Call Waiting has been activated for this telephone (see
View and modify the Properties of your own Subscriber Port on
page 63
Note: If you have already a Query call when it knocks, at least one of
both calls has to be finished first.
If you have an analog telephone where you can execute
the “take a waiting call“ function via T-Net function key/
menu, you will be able to use this comfortable operation, too.
If you have an ISDN telephone or a system telephone the
“take a waiting call“ function will be executed via an existing
function key or via menu (e.g. with “take call“; see manual of the tel-
ephone).
Note: If the waiting call is an alarm call, the currently existing call will
be terminated when accepting the waiting alarm call. How to accept
an alarm call is described on
