Surfaces
Everything voice, everywhere.
Inbound, outbound, voicemail, human handoff, calendar booking. Your carrier, your number, your numbers.
Audio + video rooms with an AI host or co-host. Phone and browser sessions share one API, one ledger.
Idempotency keys, cursor pagination, durable webhooks. Drop into Claude, ChatGPT, Cursor as a first-class tool.
Capabilities
Everything you need to run real voice traffic ships with the platform — no integration glue, no second-tier vendors.
Per-number routing into your agent or your IVR. Carrier-side webhooks normalised behind one event shape.
POST /v1/calls with idempotency keys, cost estimation, and tier-weighted concurrency fairness.
Realtime transfer to a human (or another agent) mid-conversation. Both legs stay on the same call record.
Audio + video rooms with an AI host or co-host. Same API, same ledger as phone sessions.
Let the agent invoke your APIs mid-conversation. JSON-schema tools, signed HTTP calls, auditable trail.
Every call lands with a self-hosted-LLM disposition, structured outcome, transcript, and scorecard.
Schedule follow-up SMS or email tied to a call outcome. Same provider credentials, same compliance rails.
Per-tenant voice clones with consent capture and revocation tracked end-to-end.
