Witness or tape connection
During a call a previously determined participant can be prompted to enter the
call as a “witness” via a programmed “Request silent monitor” function key. The
third participant in the call is not informed of the connection of the “witness”. The
witness can not participate in the call, only listen in.
Prerequisite: The witness or tape connection is set up on your system and the
programmed “Request silent monitor” function key is set up on your phone. You
are conducting a call. “Private call” must be deactivated.
Press the “Request silent monitor” function key briefly twice. A special ringtone
sounds on the phone of the “witness” and the message “Witness or tape con-
nection” is shown on your display and that of the “witness”.
^ The “witness” lifts the handset,
or
presses the line/function key on which the call is being carried out.
The “witness” can now listen in to the call unnoticed.
Deactivating
Press the programmed “Ring transfer” function key. The LED goes out. A call is
again signaled on the phone.
Please take note of the applicable data protection regulations for the con-
