1. A computer-implemented method of implementing a conferencing session that can be selectively operated in a continuous mode and a push-to-talk (PTT) mode, the method comprising:
establishing, by one or more computing devices, the conferencing session in the continuous mode;
detecting, by one or more computing devices, entry of a half-duplex endpoint into the conferencing session while operating in the continuous mode, the detecting comprising receiving a radio resource presence message from a radio gateway indicating the entry, wherein the half-duplex endpoint communicates using only half-duplex communication techniques;
in response to the detecting, converting, by the one or more computing devices, the conferencing session from the continuous mode to the PTT mode by implementing one or more floor control parameters in the conferencing session;
while the conferencing session is operating in the PTT mode, determining, by the one or more computing devices, that there are no half-duplex endpoints remaining in the conferencing session; and
in response to the determining, converting, by the one or more computing devices, the conferencing session back to the continuous mode.
