Feature availability - Chert

Chert includes the capabilities below. Availability is specific to your line, project, and integration. An experimental capability already exists, but needs explicit enablement and validation for your intended use.

Capability	Availability and scope
Inbound BYOR audio/video	Webhook or CLI connector; each video direction has its own requirements.
Outbound audio/video	Explicit ready line; greet only after `bridge_ready`.
Group calls and link joining	Existing experimental capabilities, enabled separately; group media acceptance pending.
Caller vision	Independent caller-capture opt-in; your agent supplies the vision model.
Multiple lines	One active call per line; confirm independent capacity for simultaneous calls.
Managed Assistants	Published persona configuration assigned to an eligible line.
Chert-hosted agent	Existing restricted-access service for eligible shared projects; `chert agent` manages it.
Chert-provided LiveKit	Offered to eligible paid Shared projects when keys are available. Customer-owned LiveKit remains supported.
Shared-line waiting	Separate allocation waitlist and opt-in outbound busy-call queue.
Direct audio transport	Existing experimental audio-only WebSocket integration, enabled by Chert; no LiveKit room or video on that path.
Additional incoming-call observation	Existing experimental busy-attempt reporting and exact-attempt decline; does not accept a second call or transfer it into the active call.
Screen/custom-media sessions	Session authorization exists; usable media requires a separately activated compatible transport.
Living services and video composition	SDK interfaces and API routes exist. Hosted execution/composition is not available; the service returns explicit unsupported/not-ready errors.

Check the media you need

Audio readiness does not establish either video direction. A successful call allocation, room join, or SDK method invocation is not proof that someone heard speech or saw moving video. Confirm the assigned line’s capabilities, then test the required directions and cleanup. See Audio and video.

Choose an integration

Use BYOR to control your agent and room lifecycle, the CLI for a foreground connector, or Managed Assistants for Chert-managed behavior. Experimental features do not require replacing an existing working integration; ask Chert which capabilities are enabled for its line.
