# Feature availability

> Existing FaceTime capabilities and the access each requires.

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](https://docs.trychert.com/facetime/group-calls.md) | 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](https://docs.trychert.com/facetime/assistants.md) | 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](https://docs.trychert.com/facetime/audio-video.md).

## Choose an integration

Use [BYOR](https://docs.trychert.com/facetime/bring-your-own-room.md) to control your agent and room lifecycle,
[the CLI](https://docs.trychert.com/facetime-cli/quickstart.md) for a foreground connector, or
[Managed Assistants](https://docs.trychert.com/facetime/assistants.md) for Chert-managed behavior. Experimental
features do not require replacing an existing working integration; ask Chert
which capabilities are enabled for its line.
