This function enables loudspeaker announcements over an active loudspeaker (for example, a loudspeaker system in a waiting room). In addition, a previously specified telephone number is called by an internal telephone. The call connection is immediately established after dialling the telephone number.
In order to make loudspeaker announcements, a device that can be used as announcement output (e. g. an a/b-Audiobox at a loudspeaker system) must be connected to the PBX. This announcement output must be created in the configuration of the PBX and assigned an internal number to call it.
