How does it actually sound? Will my customers know it is AI?

The current generation of voice agents using ElevenLabs or Cartesia is genuinely hard to distinguish from a human in normal conversation. Most callers will not realize unless you tell them. If you want full disclosure for compliance reasons (healthcare, legal), we bake it into the script.

What if the caller asks something the agent does not know?

The agent has a graceful fallback: it offers to take a message and have a human call back. You set the threshold. Every fallback is logged so we can train it out over time.

Can it transfer to a human?

Yes. We wire up live transfer to a number, a Slack notification to your team, or both. Common pattern: agent qualifies, then transfers high-intent callers to your sales team automatically.

What does the $1,500/mo operate cost cover?

Telephony costs (Twilio + Deepgram + ElevenLabs + Claude inference), monitoring, weekly script iteration, and a 24-hour response on production issues. At typical volume that is 800 to 1,500 calls a month.

Can I use my existing phone number?

Yes. Two paths: port your number to Twilio (we handle the port), or forward your existing number to the agent. Most clients forward first then port once they trust it.

What languages are supported?

English, Spanish, French, German, Portuguese, and most major languages are production-quality. We pick the voice and STT model based on your caller mix. Bilingual agents (English + Spanish) are common for US service businesses.

Voice agents need real production hardening (latency, fallbacks, escalation paths). Production Build is the default. Starter is only for very simple inbound qualifiers without booking.

Who is this for?

Built for the people who already know what is broken.

I would rather lose a deal than take on a project that is not a fit. Honest fit signals below so you can self-qualify before booking a call.

Ideal fit

Service businesses where missed calls cost real revenue (clinics, law firms, home services, real estate)
Sales teams drowning in inbound that need first-touch qualification before booking
Founders who refuse to hire a $4K/mo receptionist for $50/day worth of calls

Not a fit if

Complex outbound sales prospecting that requires multi-touch human creativity
Highly regulated industries where every call must be answered by a licensed human (some legal and medical contexts)
Businesses doing fewer than 30 calls a month: the payback math does not work yet

What is in the box?

Production-grade. Nothing left for you to figure out.

Every Inbound Voice Agent engagement ships with these components. No phase-two surprises. No upsells once the contract is signed.

Twilio or Vapi voice number provisioned and ported into your existing phone tree

Real-time STT to LLM to TTS pipeline (Deepgram + Claude + ElevenLabs) tuned for natural latency

Custom intake script trained on your offers, objections, FAQs, and qualifying criteria

Calendar integration (Cal.com, Google, Outlook, or your booking platform) with conflict checks

CRM write-back (HubSpot, Pipedrive, GoHighLevel, or webhook to anything)

SMS confirmation sent before the caller hangs up

Call recording, transcript, and summary delivered to your inbox after every call

30 days of post-launch monitoring and iteration

How does the build actually run?

Four phases. Three weeks. One engineer.

I do not disappear and surface with a demo. You see daily progress. You sign off at each phase. If something is wrong, we catch it before it ships.

Discovery (Week 1)

I shadow your current intake process. Listen to 20 recorded calls. Map every common path and edge case. You sign off on the script before a line of code is written.

Build (Week 2)

Voice agent stood up in staging. You call it from your phone, test the booking flow, push back on anything that sounds off. We iterate until it sounds like you.

Soft launch (Week 3)

Agent goes live on a forwarded number. Real callers, real bookings. I monitor every call for the first 48 hours and ship fixes the same day.

Cutover and handoff

Your main line forwards to the agent. I stay on call for 30 days, ship iterations weekly, and hand you a runbook so your team can manage prompts going forward.

Real client. Real outcome.

What does this look like in the wild?

How does the math compare to hiring?

The unit economics, plainly.

Hiring a human

$4,000 to $6,000/mo for a full-time receptionist who works 40 hours a week and sleeps 8 hours a night.

Hiring this agent

$12,000 once + $1,500/mo. Answers 24/7. Never has a bad day. Never quits.

Real outcome: Pays back in 3 to 4 months at typical service-business call volume.
