Abstract

A called radio unit may transmit different types of acknowledgements to a calling radio unit, depending on whether a user answers a call, whether a call enters a stack or whether a voice message should be left. The acknowledgements can be used by a calling radio to provide call progress indica- tions, such as informative text and/or alerts, to the user of the calling radio.
