Abstract: A method to provide ambient listening on target devices is shown. The ambience listening can be initiated by the listener or by the target device. When a console initiates an Ambience Listening (AL) call regarding a target and the target is logged into more than one device, the PTT server presents the console with a list of all concurrent devices of that user. The console is presented with additional information regarding the target, such as the location, role selected by the user on each device, and the user's operational status on each device. The operational status includes, for example, an emergency state. This enables the console to setup one or more ambience listening session with one or more appropriate devices.
