An originating mobile station seeks to establish a push-to-talk (PTT) communication session with a destination mobile station. To do this, the originating mobile station transmits a first request message that requests the PTT session. Before receiving a predefined indication that the requested PTT session has been accepted, the originating mobile station transmits a first continuation message that includes first session description information to facilitate establishment of the PTT session. A PTT server receives the first request message and, before receiving the first continuation message, transmits to the destination mobile station a second request message that requests the PTT session. The PTT server then transmits a second continuation message that includes second session description information. The destination mobile station receives the second request message and, before receiving the second continuation message, transmits an acceptance message indicating acceptance of the requested PTT session.
