The physical transport state, with start authority required before carrier mode opens.
Delegates compatibility construction, or installs bounded carrier I/O.
The provider's WebSocket, an object with the TelephonySocket shape. Typed loosely, as the released constructor was, so every existing caller keeps compiling.
Plays one chunk; completion means its carrier checkpoint returned before an interruption or a close.
A chunk with a generation is one producer's at a time: a second chunk before the first completes is refused,
and so are an older generation and, once a generation was sent, a chunk without one. A chunk without a
generation from a producer that sends none, as the voice pipeline without a call profile sends none and does
not wait for one send before the next, is admitted behind the chunks before it: each is written in order with
its checkpoint after it, without waiting for the earlier chunks to play, and at most 196608 bytes of their PCMU
wait unwritten. An interruption rejects every chunk not yet played; the chunks sent after it play.
A chunk outside TelephonyAudioChunk, such as one in an MP3 or Ogg container, is refused before output.
Readonly idStable connection identifier.
Opt-in carrier transport; the no-option construction retains the original transport behavior.
