Outgoing and incoming real-time text are displayed separately and distinguishably, the direction of each is available to assistive technology unless the RTT is closed, speaker identification offered for voice is offered for text too, and audio activity is signalled visually in real time when voice and text run together. India adds that the user's chosen Indian language is kept in the display and that the language of the text should be programmatically determinable.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
