METHOD FOR DISPATCH VOICE MESSAGING

摘要

For a push-to-talk arrangement in a dispatch call communication system ( 100 ), an originator ( 10 ) selects a group of called parties ( 11 - 14 ). A push-to-talk server ( 50 ) handles a dispatch call in a conventional manner. If all the called parties ( 11 - 14 ) do not respond, the originator is given an option to leave a message for an unavailable party ( 116 ). A multimedia message service server ( 60 ) is the storage medium for these messages. Any unavailable called subscribers ( 11 - 14 ) are provided an indication of a waiting message ( 128 ).
