Abstract: A method and corresponding device and system to provide a real-time call announcement to a called device. According to the method, a called device begins receiving call announcement media without having first engaged in session setup signaling to set up a session through which to receive the call announcement media. In normal operation, the device would disregard such incoming media, since no session has been set up for receiving the media. As disclosed, however, the device will also receive at about the same time a call setup request that seeks setup of the underlying call, and the device will treat its receipt of that call setup request as a key to allow playout of the call announcement media even though no session has been set up for receipt of the call announcement media. The called device will then play out the call announcement media as an announcement for the call.
