Adding a witness
During a call, a predefined subscriber can be requested
to listen to the call as a "witness" by means of a special
"Add witness key". The third party to the call is not in-
formed that the "witness" is listening. A witness cannot
participate in the conversation; he or she can only listen
in.
Preconditions: The Add witness function has been
configured for your system and the Add witness key on
your phone. You are conducting a call. "Privacy" must be
switched off.
Press the key twice briefly. A special signal will sound
on the "witness's" telephone and the message
Add
witness will come up on your display and on the "wit-
ness's" display.

The "witness" lifts the handset,
or
presses the line key for the line on which the call is be-
ing conducted.
The "witness" can now listen to the conversation with-
out being noticed.
When configuring and using the Add witness
function, make sure you comply with the statuto-
ry provisions relating to data protection.
