Offisky P.A. System allows you to broadcast a message to multiple devices. When using the P.A. System, it will start by receiving your announcement message, and forward your message individually to every devices in the destination call group. Unlike using real time multiple intercom where all device is connected and talk at the same time, this method will broadcast (playback) your message individually into each device after the call is picked up (either manually pickup or automatically pickup by your Phone speaker).
