Access layer

Create an account, then use the hosted CallChat client.

The live browser client is available at /app/ with homeserver callchat.org already selected. ZMath Auto runs inside that client rather than in this account-creation page.

1 Open CallChat Web The browser client is live at /app/.

2 Sign in Use your Matrix ID, username, and password.

3 Test calls Use two devices and two accounts for voice/video and Q-Call status checks.

ZMath Auto is enabled by default after local unlock. Users may explicitly choose Matrix-only sending. Recipients need the same passphrase and exact pattern image to open the additional ZMath layer.

OpenZero room agent

Zero Bot is live in an approved Matrix room with local voice enabled.

The CallChat bot bridge runs as @zero:callchat.org inside #zero-bot-lab:callchat.org. It answers commands, direct mentions, and normal lab-room greetings/product questions, uses OpenZero as the preferred local brain when available, and can post an audio reply with !zero voice.

OpenZero

Local/self-hosted model endpoint for private CPU-first replies.

Voice

Local command-triggered speech output for audio replies.

Matrix

Runs as a normal bot account inside CallChat rooms.

Safe

Approved rooms, in-RAM context, and no secret logging by default.

01 Ask the basics !zero callchat, !zero openzero, or !zero frontdesk.

02 Check the stack !zero status shows bot, OpenZero, and Voicebox reachability.

03 Keep it clean !zero rules explains privacy, secrets, and room boundaries.
