Abstract: Conveying Push-To-Talk and Push-To-Signal (PTT/PTS) information over an IP network through signaling bits defined in and propagated with the Real-Time Protocol (RTP) stream allows the PTT/PTS information to remain synchronized with the voice packets of the stream. The maintenance of synchronization of PTT/PTS signals and voice packets eliminates problems arising from failure of synchronization between the two classes of packets, notably the “shoot/don't shoot” problem. The signaling bits employed were formerly used to convey legacy network information, but are no longer in active use in the Voice-over-IP (VoIP) realm, since VoIP provides alternative pathways for their information.
