Channels

Deployment channels

live on this page

Web voice

Full-duplex speech over WebSocket with native turn-taking and barge-in — the agent stops speaking the moment a caller interjects.

Twilio · inbound + outbound

Phone

Answers your business number, or places an outbound call the moment a lead is submitted. Escalates to a human agent on request.

chat + voice notes

WhatsApp

Immediate replies, FAQ routing, lead capture, and voice-note transcription — with a live operations dashboard.

Telemetry

Measured performance, every turn

Every reply is timed from the moment the caller stops speaking to the moment the agent responds. The readouts in the console reflect this session — not marketing figures. Offline, an evaluation harness scores word-error rate, endpointing false-cutoffs, barge-in success, and tool-call correctness on every build.
