The homepage demo looked like a message recorder and the site itself blocked microphone permission. It now opens as a two-person, hands-free call room with automatic turn detection, interruptions, a mute control, timer, speaking indicators and a secondary live transcript. The microphone policy and the anonymous audio route have both been corrected.
Public call details now use SIMCOAI product names throughout. Supplier engine names no longer appear in the demo configuration, audio responses or signed browser session. The public allowance is enforced against a verified network address plus a stable browser identifier, so a forged forwarding header cannot reset it.
