AI Voice Agent
A phone agent that handles one workflow well — measurable, always on, never tired.Pick one phone workflow that costs you time or money: inbound qualification, appointment booking, FAQ deflection, missed-call recovery. We build a voice agent that owns it. Twilio + LLM + your eval rig. Real recordings, scored conversations, monthly performance report. Not a "voice assistant" — a measurable replacement for one specific phone job.

A voice agent that handles the calls you keep missing.
Inbound calls are still the #1 way customers reach SMBs — and the #1 thing falling through the cracks. We deploy a voice agent that answers, qualifies, books, and hands off cleanly to humans. TCPA-compliant, identifies as AI when asked, never makes outbound cold calls. Wired to your calendar and CRM so every conversation lands somewhere useful.
Pay LLM providers direct — no markup on tokens
Regressions caught in CI before they reach production
Hard ceiling you set — no surprise OpenAI invoices
Approval queue on every action that touches money or customers
The architecture, end to end.
No black boxes. Here's the actual shape of the system you get — with the guardrails, eval loops, and human approvals where they belong.
Voice Agent flow
Caller dials → voice in/out → reasoning → your CRM and calendar.
A real call, scripted from a deployment.
No recording, no marketing voice-over. A line-by-line walk-through of how the agent handles a typical inbound — including the moment the caller asks if they're talking to AI.
Sample call — inbound booking
Synthesized for clarity. Real deployments use your business name, hours, and approved scripts.
- AgentHi, thanks for calling Riverbend Dental — this is the front desk assistant. How can I help?
Notice line 6 \u2014 if a caller asks “are you a real person?”, the agent identifies as AI and offers a transfer. That guardrail ships on every voice deployment.

How the agent thinks.
The decision graph behind the engagement. Inputs, branches, and the point where a human stays in the loop.
The dashboard you actually use.
Every flagship engagement ships with a control panel — live activity, eval pass rate, spend cap, and an approval queue you can act on from your phone.

Concrete artifacts you keep — and what we leave out.
Working code, written docs, dashboards your team owns. We also list what this engagement deliberately does not cover, so scope is honest before you sign.

- Knowledge base of your business info, hours, services, FAQs
- CRM sync — qualified calls drop into HubSpot, Salesforce, Pipedrive, GoHighLevel, or sheet of choice
- Call recording + transcript + scoring pipeline
- Real-time dashboard: calls handled, qualified rate, average duration, cost-per-call
- Human escalation flow (warm transfer, callback request, or message capture)
- Monthly performance report
- 30 days post-launch tuning + Slack support
- Outbound cold calling (we don't build telemarketing bots)
- Multi-language (single language at launch; add via add-on)
