The method includes employing as the operating answer mode of the push-to-talk communication device one of an automatic-answer mode, an always-automatic-answer mode and a manual-answer mode. A Session Initiation Protocol/Internet Protocol core network is employed including a Session Initiation Protocol/Internet Protocol push-to-talk network server.
