| Free-flow standard-pipeline browser agent | Supported | STT, model, TTS, knowledge, and tools depend on configured providers and accounts. |
| Free-flow native speech-to-speech browser agent | Supported | Model and voice availability depend on provider configuration. |
| Flow-based agent | Alpha | Generated graph and editor work; complex branches and tool-failure paths need workflow-specific validation. |
| Quick Test, script widget, iframe widget | Supported | Check actual host origin, microphone permission, and audio playback on the customer site. |
| Existing Concierge Voice browser SDK | Supported | Customer backend owns answer generation and user identity. Full text replies, not token streaming. |
| Deferred concierge reply | Supported | Acknowledge promptly, then send one signed answer within two minutes. |
| Tool Library HTTP, knowledge retrieval, Slack action | Supported | Configure and test each real endpoint; Test Mode simulations do not execute it. |
| Python SDK tool listener | Supported | Customer hosts a dispatcher; package and alias 0.2.4 were published. |
| Basic Twilio voice conversation | Supported | Verify your own number, webhook, and tool behavior before launch. |
| Live human phone transfer | Not established | A flow handoff message does not bridge a human onto the call. |
| Outbound calling at campaign scale | Not established | Basic outbound speech was tested; scheduling, consent/suppression, and campaign controls are separate work. |
| Calendar booking | Customer integration | Use a customer HTTP tool; there is no built-in booking connector or booking guarantee. |
| Agent-assist whispering, meeting bot, real-time translation | Not offered here | These need additional product architecture and validation. |
