Abstract
To reduce a delay between a time that a user of an originating mobile station (MS) requests to set up a Push-To-Talk (PTT) call and the time that the user may begin to speak, a communication system provides a 'wake up list' of other mobile stations (MSs) that may be awakened prior to the originating MS requesting to set up a PTT call. To further reduce the delay, the user may begin speaking prior to completion of the call setup. The speech is stored and is conveyed to a called MS when the call is setup. If the call does not get setup or a user of the called MS is not present, the stored speech may be conveyed to the called MS as a voice message. The stored speech, or new speech, may also be used as an announcement of a call instead of the typical 'beep' or 'chirp.'
