Third-party monitoring

During a call, a predefined party can be prompted to join
the call as a "witness" using the "Slnt Mon Req" pro-
grammed function key. Your call partner is not informed
that a "witness" is joining the call. The "witness" cannot
participate in the call; they can only hear what is being
said.
When configuring and using third-party monitor-
ing, please note the applicable data protection
regulations.

your system and the "Slnt Mon Req" programmed func-
tion key is configured on your phone. You are conduct-
ing a call. "Privacy" must be deactivated.
