Built-in RTP (real-time transmission protocol) protocol stack, which can be used by applications to manage interactive data streams. Applications provide VoIP, one-click access, conferencing, and audio streams. These APIs can be used to start sessions, transmit, or receive data when the Network is available. The simplest use is a single remote terminal and a local device.
