Can this be extended please? I did present it at the IETF TSVWG (and asked for agenda time at the upcoming one), list discussion is here <https://mailarchive.ietf.org/arch/msg/tsvwg/Kuq5b8FrZe0kDDkFw6NY77QP6Ww/>. The big open issue is how this gets represented in the SDP.
Positive deployment feedback from Microsoft here <https://github.com/fippo/warp-snap-sped/issues/21#issuecomment-6308379637> ( improvement of 23% in P50 and 22% on P90 Transport setup latency), positive mention in the OpenAI blog post <https://openai.com/index/continuous-voice-interaction-with-gpt-live/> but this more about native apps. cheers Philipp Am Di., 30.
