Platform

Everything you need
to ship voice AI.

Outbound and inbound calls. WebRTC browser rooms. Bring your own telecom. A credit ledger that balances. Voice cloning with real consent. Tool calling, webhooks, test mode, DNC, a real-time dashboard — and SDKs in the languages you already use.

Outbound phone calls

Ring any E.164 number with a voice agent that actually listens.

  • Real-time streaming audio, barge-in, interrupt recovery
  • Per-tenant concurrency allocator so a burst never starves other tenants
  • Transparent carrier routing — keep your Telnyx / Twilio / Plivo account

Inbound call routing

Provision a DID, point it at your agent, pick up in under a second.

  • Inbound webhook verification for all three carriers
  • Configurable greeting, transfer-to-human with context passthrough
  • Voicemail, business-hours, fallback-to-human, and after-hours behaviors

Browser WebRTC rooms

Embed a voice agent in your own product — no phone number required.

  • Daily.co-backed rooms with ephemeral tokens
  • Tenant-branded rooms landing surface per design-system §8
  • Consent screen, mic permission, TTS / STT, transcript streaming

Campaigns with pacing

Upload a CSV, pick a script, let the platform worry about the law.

  • libphonenumber-validated E.164 import with custom fields
  • Per-NPA timezone inference + quiet-hours + daily-cap enforcement
  • Pacing overrides, DNC suppression, per-contact audit trail

Credit ledger that balances

Every call, every minute, every webhook — recorded as a ledger transaction.

  • Atomic hold → settle / release on every dispatch
  • Daily reconciliation with drift alerts — math that survives audit
  • Dashboard + API to read balance, transactions, and top-ups

Voice cloning with real consent

Clone a voice only after the speaker has consented. Every single time.

  • Scripted consent capture with a versioned script
  • Human-review gate before a clone enters production
  • Revocation deletes the clone plus derived assets

Functions & tool calling

Let your agent hit your APIs with OpenAI-compatible function calls.

  • JSON-schema parameter validation at runtime
  • Category-default behavior (search / transfer / schedule / lookup)
  • Function results logged per call for debugging
Learn more →

Outbound webhooks

Every important event, delivered to your endpoint with an HMAC signature.

  • Per-tenant signing secret, rotatable
  • Retries with exponential backoff and a DLQ
  • Per-endpoint event-type subscriptions
Learn more →

Test mode without burning credits

Verified numbers, allowance tracking, sandbox SMS — iterate before launch.

  • Verified-phones gate so you can only test against your own numbers
  • Monthly test allowance separate from production credits
  • Sandbox SMS gateway for verification code + opt-out keyword flow
Learn more →

Compliance + DNC tooling

TCPA, two-party consent, opt-outs, quiet hours — built in.

  • Per-state two-party consent detection with auto-disclosure
  • Opt-out keyword library + tenant extensions
  • DNC suppression list import + audit trail
Learn more →

Real-time dashboard

See every live call, every agent, every number — without reaching for the API.

  • SSE-backed live call feed
  • Per-tenant number health + caller trust signals
  • Transcript viewer, replay, and export
