Push To Talk
- A form of communications that allows users to engage in immediate communication with one or more users, providing a “walkie-talkie”-like service. However, strong coupling to data capabilities enables key features, such as: Group lists creation & management, Group sessions emulating Conferencing on Demand and, possibly, Presence & Availability.
- The communication is half-duplex: Only one person can talk at a time and all other participants hear the speech.
- Other participants can respond to this message once this initial talk-burst is complete.
- Contention of the Right-to-Speak amongst different participants is managed via Floor Control by the PoC “Service Entity”.
- The receiving participants hear the sender’s voice either by Auto Answer without any action on their part, or by Manual Answer, e. being prompted/alerted and accepting the call before hearing the sender’s voice.
