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. An existing relay can be used to switch the loudspeaker area of the loudspeaker system.
